Preface 1.1 Introduction This User Manual is intended to provide information for the proper operation of the Sotera Wireless ViSi Mobile Monitoring System™. A formal knowledge of patient monitoring and an understanding of the features and functions of the system are prerequisites for its proper use. This manual is written for trained clinicians. Although this manual describes guidelines for optimizing monitoring techniques, clinicians using this system should be trained to take and interpret patient vital signs. Automatic vital signs monitoring is an adjunct to clinical assessment; good clinical judgment should always prevail. Do not operate the ViSi Mobile Monitoring System before reading these instructions. 1.2 Warnings, Cautions and Notes Please read and adhere to all warnings, cautions and notes listed here and in the associated sections throughout this manual. 1.2.1 Definitions Warning statements alert the user to conditions or practices that could result in injury to a person, or serious adverse events associated with the use or misuse of the ViSi Mobile Monitoring System. Caution statements alert the user to conditions or practices that could result in problems with the ViSi Mobile Monitoring System associated with its use or misuse. Note: Note statements provide supplemental information to the user. Warnings, Cautions and Notes Warnings Intended Use Do not use the ViSi Mobile Monitoring System outside the intended use described in this manual. Doing so can result in a delay in or inappropriate therapy. Do not use the ViSi Mobile Monitoring System in neonatal or pediatric patients under the age of 12 years since the System has not been tested for these patient groups. Do not use the ViSi Mobile Monitor as a primary hypoxia diagnostic tool. Safety Do not use the ViSi Mobile Monitor in an MRI suite or a hyperbaric chamber. The ViSi Mobile Monitoring System has not been tested in the presence of electrosurgical devices. Avoid electrosurgery burns at the ECG monitoring sites by ensuring the electrosurgeryreturn circuit is connected properly. Monitoring may be temporarily interrupted during the use of electrocautery in the vicinity of/or on a patient being monitored with a ViSi Mobile Monitoring System. Observe the patient closely while electrocautery is in use. To ensure patient safety, use only components and accessories recommended or supplied by Sotera Wireless, Inc. Accessories must always be used in accordance with your facility’s policies and the manufacturer’s recommendations. Use only the AC adapter recommended for the ViSi Mobile Charger. Use of other AC adapters may result in damage to the unit. There may be a possible hazard caused by the summation of leakage currents when several items of equipment are interconnected. The ViSi Mobile Monitoring System has not been tested in the presence of flammable anesthetics or other flammable agents in combination with air, nitrous oxide, or oxygenenriched environments. Route the patient cabling to avoid the possibility of patient entanglement or strangulation. To ensure patient safety, the conductive parts of the ECG electrodes, including connectors and other patient-applied components, should not contact other conductive parts, or earth ground, at any time. Never connect the ViSi Mobile Chest Sensor Cable directly to the AC power outlet. Never connect the ViSi Mobile Cuff Module directly to an AC power outlet. To recharge the battery, disconnect the Cuff Module from the patient, and then place it in the ViSi Mobile Charger. 10 Warnings, Cautions and Notes Warnings To prevent possible cross-contamination, properly clean and disinfect all reusable components between patients. The ViSi Mobile Monitor should never be used to measure the NIBP of one patient while the Monitor is simultaneously connected to another patient. Do not attempt to take NIBP measurements with the ViSi Mobile Monitor while the patient is undergoing cardio-pulmonary bypass. Do not attempt to take NIBP measurements with the ViSi Mobile Monitor while the patient is being treated with an intra-aortic balloon pump or left ventricular assist device. Periodically observe the patient’s arm for signs of impaired circulation, which may be a result of measurements made too frequently. Loosen or remove the ViSi Mobile Disposable Cuff if signs and/or symptoms of prolonged impaired circulation are evident. Never place the ViSi Mobile Monitor or the ViSi Mobile Cuff Module into the ViSi Mobile Charger while connected to a patient. Never connect the ViSi Mobile Monitor directly to an AC power outlet. To recharge the battery, disconnect the Monitor from the patient, and then place it in the ViSi Mobile Charger. Do not clean the ViSi Mobile Monitor with detergents while worn by the patient. Do not place the ViSi Mobile Monitoring System on or over an implanted programmable medical device. Disposable Patient Kit All components of the ViSi Mobile Patient Kit are for single patient use only. To avoid possible cross contamination, do not reuse any of the items from the Patient Kit on a patient other than the original patient. Dispose of the ViSi Mobile Patient Kit items after use per your facility’s policy. All disposable components of the ViSi Mobile Monitoring System are for single patient use only. To avoid possible cross contamination, do not reuse any disposable items on a patient other than the original patient. Patient Monitoring Do not connect more than one ViSi Mobile Monitor to a patient. Do not connect more than one patient to a single ViSi Mobile Monitor. The ViSi Mobile Monitor, Thumb Sensor, Cuff Module, and the Chest Sensor Cable must all be connected to the same arm for the System to function correctly. 11 Warnings, Cautions and Notes Warnings The Wrist Strap should securely hold the ViSi Mobile Wrist Cradle in place without impairing circulation. Immediately loosen the Wrist Strap if the patient complains of pain, tingling, or numbness in the affected hand or wrist. Only use the ViSi Mobile Chest Sensor Cable provided by Sotera Wireless, Inc. for the ViSi Mobile Monitoring System. The Chest Sensor Cable is designed to provide defibrillation protection as indicated in the Specifications section of this manual. ViSi Mobile is designed to be compatible with the use of external defibrillators. Only use the ViSi Mobile Thumb Sensor provided by Sotera Wireless, Inc. with the ViSi Mobile Monitoring System. The ViSi Mobile Thumb Sensor is intended for use on the patient’s thumb only. Do not apply the Thumb Sensor to the patient’s fingers. Inspect patient’s skin at sensor site every 8 hours. If skin surface has been compromised, reposition the ViSi Mobile Thumb Sensor or move the Thumb Sensor to the patient’s other thumb. The Thumb Strap should securely hold the ViSi Mobile Thumb Sensor in place without impairing circulation. Immediately loosen the Thumb Strap if the patient complains of pain, tingling, or numbness in the affected thumb. Only Sotera Wireless, Inc. supplied ViSi Mobile Thumb Sensors should be used. Using non-approved Thumb Sensors may result in inaccurate SpO2 readings. Before monitoring a new patient, ensure all the sensors have been removed and that monitoring was stopped using the Stop Monitoring procedure. To prevent settings from being inadvertently changed, lock the ViSi Mobile Monitor screen (if enabled) as soon as tasks are completed. Keep all pacemaker patients under close or constant observation. Pacemaker signals can differ among pacemakers, ICDs, or CRT devices. The Association for the Advancement of Medical Instrumentation (AAMI) cautions: “In some devices, rate meters may continue to count the pacemaker rate during occurrences of cardiac arrest or some arrhythmias. Do not rely entirely upon rate meter alarms”. Other RF radiating devices (such as high powered RFID readers and Bluetooth devices) that are in close proximity with the ViSi Mobile Monitor may interfer with the Monitor’s wireless communications. During such interference, the Monitor continues to monitor and will alarm locally. If wireless communication is affected when using the Monitor in close proximity with another RF radiating device, move the other device away from the Monitor or discontinue use of the other device. 12 Warnings, Cautions and Notes Warnings All wireless devices are susceptible to radio frequency interference that can disrupt connectivity. If you observe excessive ViSi Mobile Monitoring System disconnections, notify your biomedical engineer. Excessive disconnections can cause interrupted patient monitoring; disconnections must be investigated and corrected. Locate the ViSi Mobile Remote Viewer so that clinicians can view it without obstruction. Remove any objects that obstruct the display. A qualified clinician must always be in direct view of the ViSi Mobile Remote Viewer. If the Remote Viewer display is blank, contact your Bio Med immediately for service. If a ViSi Mobile Monitor or the ViSi Mobile Remote Viewer display screen is scratched or damaged, immediately send it for servicing. A scratched or damaged screen can interfere with patient monitoring. Always consult Sotera Wireless before performing any changes to the ViSi Mobile Appliance. Server changes can result in communication failure between components of the ViSi Mobile Monitoring System. If system communication stops, monitor patients at the ViSi Mobile Monitors. Perform a risk assessment and verification before you implement a change or modification to the IT infrastructure. Changes to IT network configurations can compromise continuous vital signs monitoring and alarm delivery. Vital Signs If a vital signs measurement is questionable, retake the measurement. If the result is still questionable, use a different method of measurement. Chest Sensor Cable: ECG, Respiration, Temperature (Skin) Use all of the same type of ECG electrodes on the patient. Mixing ECG electrode types can adversely affect ECG monitoring. If ECG electrodes need to be replaced, use all of the same type of ECG electrode on the patient. Mixing ECG electrode types can adversely affect ECG monitoring. Avoid placing the ViSi Mobile Cable Securement and ECG electrodes over areas of abrasions, irritation, or other sensitive areas. If possible, remove, reposition, and replace ECG electrodes and Cable Securement if the patient complains of pain/itching at the sites. 13 Warnings, Cautions and Notes Warnings The ViSi Mobile Monitor does not provide automated arrhythmia analysis. As a result, certain arrhythmias may cause the Monitor to display inaccurate heart rates. If frequent arrhythmias are suspected, their presence should be confirmed by another method, such as a 12-lead ECG or Holter monitoring. The ViSi Mobile Monitor does not have automated ST segment analysis, therefore, if a change in the ST segment of the ECG waveform is suspected, it should be confirmed by another method, such as a 12-lead ECG. Pacemaker signals can differ among pacemakers, ICDs, or CRT devices. The Association for the Advancement of Medical Instrumentation (AAMI) cautions: “In some devices, rate meters may continue to count the pacemaker rate during occurrences of cardiac arrest or some arrhythmias. Do not rely entirely upon rate meter alarms”. All pacemaker patients should be kept under close or constant observation. External pacemakers or other external electrical stimulators may cause the ViSi Mobile Monitor to produce erroneous results. RESP (chest wall motion) can continue in the absence of ventilation (obstructed airway). Do not rely on the RESP alone to determine adequacy of ventilation. Other vital signs, such as HR and SpO2, should be assessed as well. TEMP monitoring with the ViSi Mobile Monitoring System is intended for trending purposes only and is not intended to replace core temperature monitoring. Before making clinical decisions based on the skin temperature measurement, verify the measurement using another clinically acceptable method of core temperature measurement. Impedance pneumography for the determination of respiration (RESP) is not recommended for use in the presence of mechanically induced, high frequency ventilation. Cuff Module / NIBP ViSi Mobile Disposable Cuffs are for single patient use only. To avoid possible cross contamination, do not reuse a Cuff on a patient other than the original patient. The ViSi Mobile Disposable Cuff should be snug enough to support the Cuff Module while not impairing circulation when deflated. Avoid applying the ViSi Mobile Disposable Cuff over a wound as this can cause further injury. Avoid applying the ViSi Mobile Disposable Cuff on any limb where intravascular access or therapy, or an arterio-venous (A-V) shunt, is present because of temporary interference to blood flow which could result in injury to the patient. 14 Warnings, Cautions and Notes Warnings Take care in the application of the ViSi Mobile Disposable Cuff when applying the Cuff to an arm on the same side of a mastectomy. ViSi Mobile NIBP measurements have not been clinically tested in the presence of actual or ventricular arrhythmias. Use alternative BP methods if these arrythmias are present. Inflate the ViSi Mobile Disposable Cuff only after proper application to the patient’s limb. If you are uncertain of the reliability of an NIBP measurement, repeat the measurement. If the reading is still suspect, use another method to measure the blood pressure. SpO2 Oxygen saturation measurements using SpO2 are dependent on proper sensor placement, exposure to ambient light conditions, and general patient conditions. Before making clinical decisions based on SpO2 measurements, verify the measurement using another clinically acceptable method, such as arterial blood gas analysis. High ambient light condition, including direct sunlight, may interfer with the performance of the ViSi Mobile Thumb Sensor. Low perfusion, electro-surgical devices, dysfunctional haemoglobin, the presence of certain dyes and inappropriate positioning of the ViSi Mobile Thumb Sensor may result in erroneous measurements. Alarms / Alerts When using the Monitor as a standalone device or the patient is out of network range, a responsible clinician must be within audible range of the assigned patient wearing the ViSi Mobile Monitor at all times. When alarms are paused, there is no notification of a potentially clinically significant change in the patient's vital signs. Observe the patient by other means when alarms are paused. When alarms are turned OFF, there is no notification of a potentially clinically significant change in the patient's vital signs. Observe the patient by other means when alarm limits are set to OFF. Once new alarm limits are confirmed, they cannot be changed back to the original preset limits. Once Auto Set is selected, review the newly calculated alarm limits carefully before deciding to confirm or cancel the new alarm limits. 15 Warnings, Cautions and Notes Warnings Line isolation monitor transients may resemble actual cardiac waveforms and inhibit heart rate alarms. Ensure correct electrode placement and cable arrangement to minimize line isolation monitor transients. To avoid possible hearing damage, do not place your ear too close to the ViSi Mobile Monitor that is alarming audibly. When the ViSi Mobile Monitor alarms or alerts, check the patient first to confirm that there is no immediate danger to the patient. If you test the speaker at the ViSi Mobile Remote Viewer and the tone does not sound or it is not loud enough, immediately contact a biomedical engineer.

General Description 2.1 Introduction The ViSi Mobile Monitoring System is a patient worn, portable, battery operated, physiological monitoring device indicated for the monitoring of ECG (3 lead-wire or 5 lead-wire), Heart Rate (HR), Pulse Rate (PR), Respiration (RESP), Non-Invasive Blood Pressure (NIBP), Pulse Oximetry (SpO2), and Skin Temperature (TEMP). The System comprises the ViSi Mobile Monitor, Thumb Sensor, Chest Sensor Cable (either 3 lead-wire or 5 lead-wire), Cuff Module, Charger and Patient Kit. Powered by a rechargeable battery lasting at least 12 hours, the Monitor is a lightweight (weighing approximately 125 grams) portable patient vital signs monitor featuring a high resolution, full color display touchscreen with visual and audible alarms and alerts. For ease of use, the Monitor features three interchangeable plug-in sites for the Chest Sensor Cable and Cuff Module. The industry-standard technique of oscillometry is used for non-invasively taking single measurements of the systolic and diastolic blood pressure (NIBP) as well as pulse rate. The method is based on the observation of oscillations in the sphygmomanometer cuff pressure that are caused by the oscillations of blood flow, i.e., the pulse in the patient’s upper arm. It uses a sphygmomanometer cuff like the auscultatory method, but with an electronic pressure sensor (transducer) to observe cuff pressure oscillations, electronics to automatically interpret them, and automatic inflation and deflation of the Cuff. The Cuff Module measures on inflation. The measurement is realized by a Cuff, to which the Cuff Module is attached (pneumatic connection). The electric connection to the Monitor is established through a cable that connects to its upper side. 21 Unpacking 2.2 Unpacking Remove the Monitor and associated components from the shipping cartons and examine them for signs of shipping damage.

Clinical Features 3.1 Introduction The ViSi Mobile Monitor is completely body-worn and designed to continuously measure ECG/HR, SpO2, PR, RESP, and TEMP. The ECG, SpO2, and RESP waveforms are viewable on demand. NIBP can be measured as a one-time measurement, or it can be measured automatically at predefined intervals. The Chest Sensor Cable measures the ECG/HR, RESP, and TEMP. The illustration on the next page shows a 3 lead-wire placement. 35 36 Monitor (in Wrist Cradle) Arterial Reference Line Cuff Module Upper Arm Module (Chest Sensor Cable) Upper Arm Module Securement (Flat End) ViSi Mobile Monitoring System Setup (Round End) Thumb Sensor Temperature Probe (Place against patient’s skin) Front (Place away from patient’s skin) (Cables pointing down) (Chest Sensor Cable) Chest Module Securement Chest Module Introduction Key Features 3.2 Key Features • • • • • Battery life > 12 hours Full charge reached after approximately 2 hours of charging Chest Sensor Cable options: 3 lead-wire and 5 lead-wire (HR and ECG waveforms) RESP (measurement and waveform) SpO2% (measurement and waveform) • • • • • TEMP (oC/oF) (Skin Temperature measurement) NIBP (single measurement and automatic measurements at predefined cycles) Touchscreen display Alarms and Alerts generated with visual and audible indication on the Monitor Self Test 3.3 Overview of Clinical Features The ViSi Mobile Monitoring System is a lightweight portable patient vital signs monitor featuring a high resolution, full color display with visual and audible alarms and alerts. The ViSi Mobile Monitor is completely body-worn and designed to continuously measure ECG/HR, SpO2, PR, RESP, and TEMP. ECG, SpO2, and RESP waveforms are viewable on demand. NIBP can be measured as a one-time measurement, or it can be measured automatically at programmed intervals. The Monitor is powered by a rechargeable battery. For ease of use, the Monitor features interchangeable plug-in sites for the ViSi Mobile Chest Sensor Cable and ViSi Mobile Cuff Module. The Chest Sensor Cable measures the ECG/HR (with a 3 lead-wire or 5 lead-wire), RESP, and TEMP. 3.3.1 ECG Monitoring and Heart Rate (HR) Monitoring With the 3 lead-wire Chest Sensor Cable, the Monitor continuously monitors Lead II. With the 5 lead-wire Chest Sensor Cable, the Monitor continuously monitors seven ECG lead views simultaneously, Leads I, II, III, aVR, aVL, aVF, and a V lead. The ECG waveform can be displayed one lead at a time. The ability to monitor multiple leads simultaneously improves beat detection to determine the HR and minimizes false detections as a result of muscle artifact. 3.3.2 Respiration Rate (RESP) Monitoring RESP is determined by measuring the AC impedance between the RA and LL ECG electrodes. Chest wall motion, rise and fall, associated with inspiration and expiration is automatically detected when the RA and LL leads are placed in the standard Lead II configuration on the chest, or in the MCL configuration. 37 Overview of Clinical Features RESP is determined from the frequency of the respiration (chest wall motion). The respiration channel can detect the absence of RESP. RESP (chest wall motion) can continue in the absence of ventilation (obstructed airway). Do not rely on the RESP alone to determine adequacy of ventilation; other vital signs such as HR and SpO2 should be assessed as well. 3.3.3 Skin Temperature (TEMP) Monitoring TEMP is continuously measured skin surface temperature as measured by the probe located on the underside of the Chest Module. The probe must be placed directly in contact with the patient’s skin. TEMP can be displayed in °C or °F. See To apply the Chest Sensor Cable on page 59. Note: Skin temperature may not be the same as core body temperature or temperature measured from oral or tympanic methods. Note: Skin temperature representative of skin surface temperature will take approximately 6 minutes from the time the Chest Module is applied. TEMP monitoring with the ViSi Mobile Monitoring System is intended for trending purposes only and is not intended to replace core temperature monitoring. Before implementing therapy based on the skin temperature measurement, verify the measurement using another clinically acceptable method of core temperature measurement. 3.3.4 Pulse Oximetry (SpO2 and Pulse Rate) Monitoring The Pulse Oximetry channel non-invasively continuously measures the functional oxygen saturation of the hemoglobin in arterial blood using the transmittance across the base of the thumb. A pulsatile arterial source at the base of the thumb is required to measure the SpO2. In the absence of a HR source from an ECG, the Pulse Rate (PR) can be measured and displayed from the SpO2 channel. Oxygen saturation measurements using SpO2 are dependent on proper sensor placement, exposure to ambient light conditions, and general patient conditions. Before making clinical decisions based on SpO2 measurements, verify the measurement using another clinically acceptable method, such as arterial blood gas analysis. High ambient light condition, including direct sunlight, may interfer with the performance of the ViSi Mobile Thumb Sensor. Low perfusion, electro-surgical devices, dysfunctional haemoglobin, the presence of certain dyes and inappropriate positioning of the ViSi Mobile Thumb Sensor may result in erroneous measurements. 38 Display Screens 3.3.5 NIBP Monitoring The ViSi Mobile Cuff Module is intended for measuring arterial blood pressure (systolic and diastolic) using a Cuff. Measurements may be initiated manually (one at a time), or automatically at selectable predefined intervals of 5, 10, 15, 30, 60, 90 and 120 minutes. The accuracy of NIBP measurements is influenced by several factors: • • • • Correct cuff size Correct cuff placement on the arm The position of the upper arm in relation to the heart at the time of the measurement Motion artifacts 3.4 Display Screens This section describes various screens displayed on the ViSi Mobile Monitor. Each screen is accessed by interacting with the touchscreen display. 3.4.1 Battery Charge Screen The Battery Charge screen displays the battery status while the Monitor is charging in the Charger.

Operation 4.1 Introduction The ViSi Mobile Monitoring System is a sophisticated multi-parameter vital signs monitor. In order to optimize the user of ViSi, please adhere to the following instructions related to patient set-up, initiating monitoring and the removal of the System. 4.2 Preparing for a New Patient In order to set up the complete ViSi Mobile Monitoring System, you will need the following components: • • • • • ViSi Mobile Patient Kit (select size) ViSi Mobile Monitor ViSi Mobile Cuff Module ViSi Mobile Thumb Sensor ViSi Mobile Chest Sensor Cable (3 lead-wire or 5 lead-wire configuration) Note: Skin preparation equipment (skin preparation pads, scissors and/or razor as needed) not included. 4.2.1 Inspecting the Equipment and Accessories Before starting patient monitoring, you should visually inspect the ViSi Mobile Monitoring System components: 1. For each component, examine the exteriors for cleanliness and general physical conditions. Ensure the housings are not cracked or broken, that everything is present, there are no spilled liquids and no signs of abuse. 2. Inspect all component cables for damage. Check their strain relief for general condition. Ensure there are no breaks in the insulation. If any cables show signs of damage, do not use. 3. Inspect all disposable accessories (Wrist Cradle, Cuff, Thumb Strap, Securements, etc). If any show signs of damage or pre-use, do not use. 45 Preparing for a New Patient 4.2.2 Applying Sensors Applying the sensors is simple and may be done in any order. At the completion of the setup, the components of the ViSi Mobile Monitoring System will be connected to the patient as shown in the diagram below. Upper Arm Module (on Chest Sensor Cable) Chest Module (on Chest Sensor Cable) (Temperature probe on the back side of the Chest Module must be placed against the patient’s skin) Cuff Module (Applied to upper arm) Monitor (in Wrist Cradle) Thumb Sensor Whenever a sensor is connected to the Monitor, a self-test of that sensor is initiated automatically to verify the sensor is in good working order. If the sensor and Monitor speaker are in good working order, you will hear a double beep. This process takes a few seconds, after which monitoring of the selected vital sign commences as soon as the sensor is connected to the patient. The double beep is also a validation that the Monitor speaker is in good working order and that audio tones associated with alarms will be annunciated accordingly. Alarm limits are set automatically according to default settings. See 6.6 Manage Alarm Limits on page 104. Successful vital signs monitoring is dependent on several factors: • • • • • • 46 Determining the vital signs to be monitored Selecting a Monitor and Cuff Module that are adequately charged for maximum duration of uninterrupted monitoring Selecting the 3 lead-wire or 5 lead-wire Chest Sensor Cable Selecting the appropriately sized Cuff (from the Patient Kit) Preparing the skin for ECG electrode placement Correctly applying all sensors used for monitoring Preparing for a New Patient Note: The battery in the Monitor will deplete at a faster rate when sensors are connected to the Monitor, even when monitoring has not been started. Note: The Chest Module includes a body surface temperature probe. To ensure proper function, place the temperature sensor on the body with the Chest Module “Front” label facing forward (away from the patient’s skin). 4.2.3 Selecting Vital Signs to Monitor The following vital signs may be monitored: • • • ECG (one or seven simultaneous leads, using the 3 lead-wire or 5 lead-wire Chest Sensor Cable respectively) HR (from the ECG) RESP (optional) TEMP (Skin Temperature) SpO2 NIBP PR (from the Thumb Sensor) SYS DIA PR (from NIBP) 4.2.4 Selecting the ViSi Mobile Chest Sensor Cable The Chest Sensor Cable provides the sensors to monitor the ECG, HR, RESP (optional), and TEMP. Note: The skin surface temperature probe is on the underside of the Chest Module. It must be placed on the skin surface in order to properly measure skin surface temperature. Select the Chest Sensor Cable that best suits the monitoring needs of your patient: • • The 3 lead-wire Chest Sensor Cable monitors Lead II, or the MCL configuration. The 5 lead-wire Chest Sensor Cable monitors seven leads of ECG simultaneously in lead configurations I, II, III, aVR, aVL, aVF, and a V lead. The specific V lead depends on the placement of the V electrode. 4.2.5 Selecting the ViSi Mobile Patient Kit The System’s disposable components, including the Cuff are contained in the Patient Kit. The Patient Kits are designated as S, M, and L based on the Cuff size. Selection of the correct ViSi Mobile Disposable Cuff size is necessary to ensure accurate NIBP measurements. A Cuff that is too small can result in a falsely high NIBP measurement. A Cuff that is too large can result in a falsely low NIBP measurement. 47 Preparing for a New Patient Cuff / Patient Kit Size Arm Circumference (cm) Adult S 20 – 26 Adult M 25 – 34 Adult L 32 – 43 4.2.6 Checking the Battery Charge of the ViSi Mobile Monitor and Cuff Module Before you start to monitor your patient with the System, you will need to select both a Monitor and a Cuff Module that are adequately charged for maximum duration of uninterrupted monitoring. To check the battery charge of the Monitor 1. Turn on the display by touching the screen while the Monitor is in the Charger. 2. Verify that the large battery icon in the center of the screen is green. A full green battery symbol indicates that the battery is fully charged. A partially green battery symbol indicates the degree to which the battery is charged. The full monitoring period will not be achieved unless the battery is fully charged A yellow battery symbol indicates the battery is low with less than 2 hours of monitoring time left. A red battery symbol indicates the battery is critically low with less than 30 minutes of monitoring time left. Fully Charged Battery Low Battery Critically Low 48 Preparing for a New Patient To check the battery charge of the Cuff Module Press Battery Status button on the front of the Cuff Module. There is a row of eight colored lights on the front surface of the Cuff Module. Illuminated green lights indicate that the level of the battery charge is adequate for at least several NIBP measurements. When six illuminated green lights are visible on the Cuff Module, the Module is fully charged. When the yellow light is illuminated, the battery charge is low. At least one NIBP measurement is possible. When the red light is illuminated, the battery charge is too low for any further NIBP measurements. Battery Status Indicator (LEDs) Battery Status button 49 Applying ViSi Mobile Monitoring System / Initiate Monitoring 4.3 Applying ViSi Mobile Monitoring System / Initiate Monitoring The ViSi Mobile Monitor may be used to monitor one vital sign, such as SpO2, or multiple vital signs simultaneously. Apply the appropriate sensor for each vital sign to be monitored, as described below. Start by selecting the appropriately sized Patient Kit (S, M, L). The Monitor’s ECG channel is capable of monitoring patients with an Implanted Pacemaker (PM), Implantable Cardioverter-Defibrillator (ICD), or Cardiac Resynchronization Therapy (CRT) device. A vertical dashed line before the P wave (atrial pace), and before the QRS (ventricular pace) indicate paced events. In the case of biventricular pacing (CRT), two vertical dashed lines occur before the QRS. Note: Stimulus pulses from a pacemaker, as indicated by the vertical dashed lines, are not counted as heartbeats, as defined by the pacer pulse rejection specification. See 9. Specifications on page 125. Pacemaker signals can differ among pacemakers, ICDs, or CRT devices. The Association for the Advancement of Medical Instrumentation (AAMI) cautions: “In some devices, rate meters may continue to count the pacemaker rate during occurrences of cardiac arrest or some arrhythmias. Do not rely entirely upon rate meter alarms”. All pacemaker patients should be kept under close or constant observation. External pacemakers or other external electrical stimulators may cause the ViSi Mobile Monitor to produce erroneous results. Only use the ViSi Mobile Chest Sensor Cable provided by Sotera Wireless, Inc. with the ViSi Mobile Monitoring System. The Chest Sensor Cable is designed to provide defibrillation protection as indicated in the Specifications section of this manual. ViSi Mobile is designed to be compatible with the use of external defibrillators. Only use the ViSi Mobile Thumb Sensor provided by Sotera Wireless, Inc. with the ViSi Mobile Monitoring System. All components of the ViSi Mobile Patient Kit are for single patient use only. To avoid possible cross contamination, do not reuse any of the items from the Patient Kit on a patient other than the original patient. Dispose of the ViSi Mobile Patient Kit items after use per your facility’s policy. The ViSi Mobile Monitor, Thumb Sensor, Cuff Module, and the Chest Sensor Cable must all be connected to the same arm for the System to function correctly. 50 Applying ViSi Mobile Monitoring System / Initiate 4.3.1 Applying the ViSi Mobile Wrist Cradle If there are no contraindications, for patient comfort, apply the Wrist Cradle to the patient’s wrist (either left or right). To apply the Wrist Cradle 1. Remove the Wrist Cradle from the Patient Kit. 2. Orient the Wrist Cradle with the flat end pointed towards the elbow, slide the patient’s hand through the Wrist Strap and position the cradle on the top side of the wrist. 3. Pull snugly and secure. Flat End Rounded End The Wrist Strap should securely hold the ViSi Mobile Wrist Cradle in place without impairing circulation. Immediately loosen the Wrist Strap if the patient complains of pain, tingling, or numbness in the affected hand or wrist. 4. Placing the flat end in first, insert the Monitor into the Wrist Cradle and push down. When the Monitor is pushed down all the way, you will hear a “clicking” sound. Note: The Monitor is not completely secured within the Wrist Cradle until the Thumb Sensor or Locking Plug is inserted into the connector on the rounded end of the Monitor. Flat End Wrist Cradle Rounded End 51 Applying ViSi Mobile Monitoring System / Initiate Monitoring When inserting the ViSi Mobile Monitor into the Wrist Cradle, ensure proper alignment: flat end to flat end and the round end is pointing down towards the wrist. To avoid damage from dropping the ViSi Mobile Monitor, ensure that the Wrist Strap is snugly wrapped around the wrist. To avoid damage from dropping the ViSi Mobile Monitor, make sure that the Monitor is securely snapped into the ViSi Mobile Wrist Cradle. 5. If you are not performing SpO2 monitoring, secure the Monitor to the cradle by inserting a Locking Plug into the opening on the rounded end of the Monitor. Locking Plug 4.3.2 Applying Sensors The ViSi Mobile Monitor, Thumb Sensor, Cuff Module, and the Chest Sensor Cable must all be connected to the same arm for the System to function correctly. Vital signs monitoring starts automatically as soon as a sensor is connected to the Monitor and attached to the patient. When performing a patient setup, the alarms pause automatically, allowing you to complete the setup before the alarms are turned on. Sensors are designed to securely plug into the Monitor so that they cannot fall out unintentionally. You should hear a double-beep sound when a sensor is inserted correctly. 52 Applying ViSi Mobile Monitoring System / Initiate 4.3.3 Applying the ViSi Mobile Thumb Sensor The ViSi Mobile Thumb Sensor is intended for use on the patient’s thumb only. Do not apply the Thumb Sensor to the patient’s fingers. To apply the Thumb Sensor 1. Remove the Thumb Cradle from the Patient Kit. 2. Insert the Thumb Sensor into the Thumb Cradle such that the sensor optics are pointing away from the Thumb Cradle. Optics Thumb Sensor Thumb Cradle 3. Place the Thumb Sensor at the base of the thumb and secure it with the Thumb Strap. 53 Applying ViSi Mobile Monitoring System / Initiate Monitoring The Thumb Cradle is designed to hold the Thumb Sensor in place securely without impairing circulation. Ensure that the ViSi Mobile Thumb Sensor is securely fastened. A Thumb Sensor that is wrapped too tight or too loose can adversely affect SpO2 measurement. Inspect patient’s skin at sensor site every 8 hours. If skin surface has been compromised, reposition the ViSi Mobile Thumb Sensor or move the Thumb Sensor to the patient’s other thumb. 4. Check the patient’s thumb for good color and circulation to ensure that the Thumb Sensor has not restricted circulation. The Thumb Strap should securely hold the ViSi Mobile Thumb Sensor in place without impairing circulation. Immediately loosen the Thumb Strap if the patient complains of pain, tingling, or numbness in the affected thumb. 5. Connect the Thumb Sensor into the connector on the rounded end of the Monitor with the connector contacts facing upwards. The monitoring of SpO2 and the PR starts after a few seconds. Alarm limits are set automatically according to predefined settings. See 6.6 Manage Alarm Limits on page 104. Pulsating Indicator Bar 6. While palpating the pulse in the wrist of the arm opposite the Monitor, watch the pulsating indicator bar to the right of the SpO2 numeric and ensure that the bar fluctuates with the pulse. The pulsating indicator bar confirms signal adequacy by moving up and down in sync with the detection of pulsating blood flow. Use the pulsating indicator bar to confirm the Thumb Sensor is optimally placed. It may take several seconds for the signal to stabilize. 54 Applying ViSi Mobile Monitoring System / Initiate The indicated PR should match the palpated pulse rate. PR is replaced with HR when measuring ECG and SpO2 simultaneously. Note: If sensing of the SpO2 or the PR is erratic, loosen the Thumb Strap from the thumb and reposition the Thumb Sensor until a stable SpO2 and PR are obtained. Re-secure the Thumb Sensor with the Thumb Strap. Only Sotera Wireless, Inc. supplied ViSi Mobile Thumb Sensors should be used. Using non-approved Thumb Sensors may result in inaccurate SpO2 readings. 55 Applying ViSi Mobile Monitoring System / Initiate Monitoring 4.3.4 Applying the ViSi Mobile Chest Sensor Cable and ECG Electrodes Use all of the same type of high quality ECG electrodes on the patient. Mixing ECG electrode types can adversely affect ECG monitoring. To ensure patient safety, the conductive parts of the ECG electrodes, including connectors and other patient-applied components, should not contact other conductive parts, or earth ground, at any time. Only use the ViSi Mobile Chest Sensor Cable provided by Sotera Wireless, Inc. with the ViSi Mobile Monitoring System. The Chest Sensor Cable is designed to provide defibrillation protection as indicated in the Specifications section of this manual. ViSi Mobile is designed to be compatible with the use of external defibrillators. Never connect the ViSi Mobile Chest Sensor Cable directly to the AC power outlet. Skin Preparation Skin preparation and ECG electrode placement directly impact the quality of the ECG signal and HR determinations. The following steps are recommended for skin preparation: • • • Select ECG electrode sites on the patient’s chest Choose sites that are flat, avoiding fatty areas and major muscles. For patient comfort, avoid placing ECG electrodes where lying on the side will put pressure on the ECG electrode. Sites just below the middle of the clavicles are good locations for the RA and LA ECG electrodes. If needed, shave or clip hair in approximately a 1.5 to 2-inch diameter area for each ECG electrode site. Also, for patient comfort, shave or clip hair from the areas where the Chest Sensor Cable and upper arm sensor are secured. Thoroughly clean the sites to remove excess skin oils, skin cells, and residue from the ECG electrode sites. You may use isopropyl alcohol prep pads or another skin preparation pad, or soap and water. Gently rub the site dry with a dry gauze pad or other dry pad. Note: To avoid skin irritation, avoid areas that appear damaged; remove ECG electrodes if the patient complains of pain/itching; replace ECG electrodes per the electrode manufacturer’s instructions and place on different sites. Note: Only use snap-on type electrodes. 56 Applying ViSi Mobile Monitoring System / Initiate 3 lead-wire and ECG Electrode Placement With the 3 lead-wire Chest Sensor Cable, the ECG channel provides Lead II only. The ECG electrode placement shown in the diagram below is recommended for Lead II monitoring Lead Wire Color Code - U.S. (AAMI) RA - White LA - Black LL - Red Lead Wire Color Code - International (IEC) R - Red L - Yellow F - Green 57 Applying ViSi Mobile Monitoring System / Initiate Monitoring 5 lead-wire and ECG Electrode Placement With the 5 lead-wire Chest Sensor Cable, the ECG channel is capable of monitoring seven leads simultaneously (Lead I, II, III, aVR, aVL, aVF, and a V lead). The ability to monitor multiple leads simultaneously improves beat detection to determine the HR and minimizes false detections as a result of artifact. The ECG electrode placement shown in the diagram below is recommended. Lead Wire Color Code - U.S. (AAMI) RA - White LA - Black LL - Red V - Brown RL - Green V1 4th intercostal space (just right of sternum) V2 4th intercostal space (just left of sternum) V3 Midway between V2 and V4 V4 Mid clavicular line, 5th intercostal space V5 Anterior axillary line, between V4 and V6 V6 Mid axillary line, horizontal with V4 Lead Wire Color Code - International (IEC) R - Red L - Yellow F - Green C - White N - Black Note: Place the V lead in the position appropriate to your monitoring requirements: V1, V2, V3, V4, V5 or V6. Note: The ECG waveform can be displayed one lead at a time on the ViSi Mobile Monitor. 58 Applying ViSi Mobile Monitoring System / Initiate To apply the Chest Sensor Cable Avoid placing the ViSi Mobile Cable Securement and ECG electrodes over areas of abrasions, irritation, or other sensitive areas. If possible, remove, reposition, and replace ECG electrodes and Cable Securement if the patient complains of pain/itching at the sites. 1. 2. 3. 4. Remove the ECG electrodes from the Patient Kit. Apply the ECG electrodes to the prepared sites on the chest as shown. Remove the large Cable Securement from the Patient Kit. Secure the Chest Module of the Chest Sensor Cable between the sternum and the shoulder (same side as the Monitor) using the large Cable Securement. Note: The Chest Sensor Cable should be oriented vertically. Do not orient the sensor more than 45 degrees to the left or right. Note: Ensure the “Front”, “ViSi Mobile” and “Defibrillation” labels on the Chest Module of the Chest Sensor Cable are facing outwards away from the patient’s skin. Note: Ensure the “barcode” label and the Temperature sensor on the Chest Modole of the Chest Sensor Cable are placed inwards directly against the patient’s skin. Note: For patient comfort, shave or clip the hair in the areas where the Cable Securement come in contact with the chest. 5. Apply the lead wires from the Chest Sensor Cable to the ECG electrodes. Note: For patient comfort lead wires may be attached to ECG electrodes prior to applying the electrodes to the patient’s chest. 6. Remove the small Cable Securement from the Patient Kit. 59 Applying ViSi Mobile Monitoring System / Initiate Monitoring 7. Secure the Upper Arm Module of the Chest Sensor Cable on the outside of the upper arm using the small Cable Securement. Chest Module (front view) (Place this side away from the patient’s skin) Small Block Large Block Temperature Probe Lead wires pointing downwards Chest Module (rear view) (Place this side against patient’s skin Note: The default ECG configuration is Lead II. 8. Plug the Chest Sensor Cable into any of the three ports on the flat end of the Monitor with the connector contacts facing upwards. Note: Monitoring of ECG, HR, RESP (optional), and TEMP starts automatically. Alarm limits are set automatically according to predefined settings. Note: Only attach one ViSi Mobile Chest Sensor Cable to the patient and ViSi Mobile Monitor. Insert with connectors contacts facing upwards 9. While palpating the pulse in the wrist of the arm opposite the Monitor, watch the beating heart symbol at the top left of the HR numeric to ensure that it fluctuates with the patient’s heart beat. The heart symbol beats with the pulse to confirm that the sensor is optimally placed. It may take several seconds for the signal to stabilize. 60 Applying ViSi Mobile Monitoring System / Initiate • • The indicated HR should match the palpated pulse rate. If the indicated HR is erratic or doesn’t match the palpated pulse rate, check to make sure that the ECG electrodes and lead wires are secure. Note: In rare circumstances, the ECG electrodes may need to be placed in different locations to improve the ECG signal. 10. While observing the patient, count the respiration rate and compare it to the RESP rate on the Monitor. It may take several seconds for the signal to stabilize. • The indicated RESP should match the observed rate. • If the indicated RESP is erratic or doesn’t match the observed rate, check to make sure that the ECG electrodes and lead wires are secure. Note: The Temperature sensor takes several minutes to reach a stable temperature reading. 4.3.5 Applying the ViSi Mobile Cuff Module and Disposable Cuff ViSi Mobile Disposable Cuffs are for single patient use only. To avoid possible cross contamination, do not reuse a Cuff on a patient other than the original patient. To apply the Cuff Module 1. Remove the Cuff from the Patient Kit. 2. Squeeze as much air out of the Cuff as possible. 3. Ensure that the patient is resting so that the upper arm muscles are relaxed. The level of the middle of the Cuff, while the arm is at rest, should be approximately at heart level. 4. Wrap the Cuff around the upper part of the same arm to which the Monitor is attached. • Align the bottom part of the Cuff approximately 1” above the antecubital fossa. • Align the artery marker on the Cuff with the brachial artery. • The connector for the Cuff Module should be to the outside of the arm, away from the body. • Have the patient remain still to avoid the introduction of unnecessary motion artifact. Note: The ViSi Mobile Disposable Cuff is designed to be used on the same arm with the other ViSi Mobile sensors. It may temporarily cause the loss of function of other devices (not ViSi Mobile) simultaneously used on the same limb. Note: Only attach one ViSi Mobile Cuff Module to the ViSi Mobile Monitor. The ViSi Mobile Disposable Cuff should be snug enough to support the Cuff Module while not impairing circulation when deflated. Avoid applying the ViSi Mobile Disposable Cuff over a wound as this can cause further injury. 61 Applying ViSi Mobile Monitoring System / Initiate Monitoring Avoid applying the ViSi Mobile Disposable Cuff on any limb where intravascular access or therapy, or an arterio-venous (A-V) shunt, is present because of temporary interference to blood flow which could result in injury to the patient. Take care in the application of the ViSi Mobile Disposable Cuff when applying the Cuff to an arm on the same side of a mastectomy. ViSi Mobile arterial measurements have not been clinically tested in the presence of actual or ventricular arrhythmias. Use alternative BP methods if these arrythmias are present. 5. Connect the Cuff Module securely to the Cuff with the cable in the direction of the Monitor. Inflate the ViSi Mobile Disposable Cuff only after proper application to the patient’s limb. 6. Plug the Cuff Module into any of the open ports on the flat end of the Monitor with the connector contacts facing upwards. Insert with connector contacts facing upwards 62 Removing ViSi Mobile Monitoring System The Start symbol on the NIBP Start button blinks, prompting you to start a Cuff inflation. See Taking a NIBP Measurement on page 75 for instructions on how to take a NIBP measurement. 4.4 Removing ViSi Mobile Monitoring System All disposable components of the ViSi Mobile Monitoring System are for single patient use only. To avoid possible cross contamination, do not reuse any disposable items on a patient other than the original patient. To remove Cuff and Cuff Module 1. Disconnect the Cuff Module from the Monitor: Grasp the Cuff Module cable near the plug and, while holding the Monitor still, pull out the plug. 2. Unwrap the Cuff from the arm. 3. If the patient will no longer be monitored: • Disconnect the Cuff Module from the Cuff. • Dispose of the Cuff according to your facility’s policy. To remove the Chest Sensor Cable 1.

Holding the ends of the Thumb Sensor between your thumb and index finger, gently bend the Thumb Sensor backwards until it releases from the Thumb Cradle. 4. If the patient will no longer be monitored, dispose of the Thumb Cradle and Thumb Strap according to your facility’s policy. To remove the Wrist Cradle and Monitor 1. For ease of removal of the Wrist Cradle and Monitor, ensure all sensors are disconnected from the Monitor. 2. Remove the Monitor from the Wrist Cradle. 3. Unwrap the Wrist Strap from the patient’s wrist and remove the Wrist Cradle from the patient’s wrist. 4. If the patient will no longer be monitored, dispose of the Wrist Cradle and Wrist Strap according to your facility’s policy. 63 Removing ViSi Mobile Monitoring System Clean the reusable components of the System: Monitor, Chest Sensor Cable, Thumb Sensor, and Cuff Module, in accordance with your facility’s procedures and the cleaning recommendations in this manual. See 7. User Maintenance on page 109. 64 5. Patient Monitoring 5.1 Introduction The ability to monitor patients with a patient-worn ViSi Mobile Monitoring System opens up many opportunities to assess vital signs during all phases and activities involved in a patient’s recovery process. 65 Monitoring the Patient 5.2 Monitoring the Patient RESP (chest wall motion) can continue in the absence of ventilation (obstructed airway). Do not rely on the RESP alone to determine adequacy of ventilation. Other vital signs, such as HR and SpO2, should be assessed as well. Impedance pneumography for the determination of respiration (RESP) is not recommended for use in the presence of mechanically induced, high frequency ventilation. The ViSi Mobile Monitor does not provide automated arrhythmia analysis. As a result, certain arrhythmias may cause the Monitor to display inaccurate heart rates. If frequent arrhythmias are suspected, their presence should be confirmed by another method, such as a 12-lead ECG or Holter monitoring. The ViSi Mobile Monitor does not have automated ST segment analysis, therefore, if a change in the ST segment of the ECG waveform is suspected, it should be confirmed by another method, such as a 12-lead ECG. Oxygen saturation measurements using SpO2 are dependent on proper sensor placement and general patient conditions. Before making clinical decisions based on SpO2 measurements, verify the measurement using another clinically acceptable method, such as an arterial blood gas analysis. TEMP monitoring with the ViSi Mobile Monitoring System is intended for trending purposes only and is not intended to replace core temperature monitoring. Before making clinical decisions based on the skin temperature measurement, verify the measurement using another clinically acceptable method of temperature measurement. To prevent settings from being inadvertently changed, lock the ViSi Mobile Monitor screen (if enabled) as soon as tasks are completed. The ViSi Mobile Monitoring System does not support printing capability. 66 Monitoring the Patient 5.2.1 Unlocking the Monitor If your System is configured to require authorization to view the Vital Signs screen, you must first unlock the Monitor by entering a PIN code. If you do not have a PIN code, please see your system administrator. If your System is not configured to require authorization, the Enter Pin Code screen does not appear. To unlock the Monitor 1. With one finger, touch the Monitor’s screen for two seconds to activate the Monitor’s display. The Patient View screen appears. 2. Touch Unlock in the lower left corner of the screen. The Enter PIN Code screen appears. Message area Return to previous screen 3. Enter PIN code on the PIN code pad. As PIN digits are entered, a white dot appears in the message area for each digit entered and the Return to Previous Screen button changes to a Cancel button. 4. Touch Confirm to enter the PIN code and confirm authorization. 67 Monitoring the Patient If you touch the Confirm button the system navigates to the Vital Signs screen (when a valid PIN code has been entered). If you touch the Cancel button, the entered PIN code is cleared and the Return to Previous Screen button appears allowing to return to the Patient View screen. Note: When an invalid PIN code is entered, the outline of the PIN code buttons will flash red and the entered PIN code is cleared. 5.2.2 Locking the Monitor When you have finished working with the Monitor, you should lock the Monitor to prevent the patient from accidentally accessing clinical settings. To lock the Monitor 1. When you are finished interacting with the patient and the Monitor, touch Lock. The Vital Signs screen is locked to prevent settings from being inadvertently changed. The Patient View screen appears. 68 Monitoring the Patient 5.2.3 Viewing Vital Signs Vital signs monitoring, with alarms, starts as soon as a sensor is connected to the patient and plugged into the Monitor. When there has been no interaction with the Monitor for a period of time, the display goes into Quiet Monitoring. To view vital signs 1. With one finger, touch the Monitor screen for two seconds to activate the display. 2. Enter your PIN code if required. See To unlock the Monitor on page 67. The Vital Signs screen appears and displays all currently monitored vital signs. Cuff Module connected Cuff Module not connected Note: If the Cuff Module is not connected, the Start NIBP button is disabled and the NIBP numeric display area is blank. Note: The vital sign measurements are refreshed every 3 seconds. 69 Monitoring the Patient 5.2.4 Viewing Waveforms Associated with Vital Signs Waveforms move across the display from left to right. A sweep bar erases the oldest waveform and replaces it with the newest waveform as it moves from left to right. Sweep Bar Pacer Spike The speed of the waveform display (sweep speed) is scaled to 25 mm/sec for ECG and SpO2 waveforms. The sweep speed of the RESP waveform display is scaled to 6.25 mm/sec. The RESP frequency is less than the ECG or SpO2. The slower sweep speed for the RESP waveform compensates for the lower frequency of activity in order to display several RESP cycles on the display. Note: The NIBP measurement does not have a waveform. To view the ECG waveforms Depending on which Chest Sensor Cable is connected (3 lead-wire or 5 lead-wire), several views (leads) of the ECG waveform may be available for view. Note: It is recommended that you step through the available ECG waveform leads to confirm the ECG setup is correct. Note: When using a 3 lead-wire Chest Sensor Cable, only a Lead II waveform is available. Note: There is no pacer detection with a 3 lead-wire Chest Sensor Cable. 70 Monitoring the Patient 1. Touch the HR numeric. ECG Lead selection The top third of the display is replaced with the ECG waveform. The displayed lead is indicated to the left of the waveform. The square wave indicates the standard calibration of the ECG waveform. To view other leads with the 5 lead-wire Chest Sensor Cable 1. Touch ECG Lead Selection or the waveform. The lower part of the display is replaced with Lead Selection buttons. 2. Select the lead corresponding to the waveform that you want to view. All available leads can be viewed one at time from this view. Note: Selecting different leads to view has no affect on monitoring. All available leads are monitored simultaneously and continuously. The lead selection affects only the display. 3. Touch Return to Previous Screen to exit this view. The display returns to the previous view of the ECG waveform and vital signs. 71 Monitoring the Patient 4. To return to the main Vital Signs screen, touch the HR numeric. The ECG waveform is no longer displayed. Note: When you touch a vital sign, its corresponding waveform is displayed, even if another waveform is currently displayed. Input Overload / Dynamic Range The ViSi Mobile Monitor display indicates an input overload condition (i.e. the input dynamic range of the amplifier associated with the displayed ECG lead has been exceeded) by displaying the trace in red at the top (or bottom) of the ECG waveform display area. Amplifier is overloaded due to an input that exceeds the positive limit of the dynamic range on a continuous basis Positive limit of the dynamic range is being exceeded only at the peaks of the QRS complex of the ECG waveform Dynamic range of the ECG amplifier has not been exceeded, but in which the peaks of the QRS complex of the ECG waveform extend beyond the upper edge of the display area 72 Monitoring the Patient To view the RESP waveform 1. Touch the RESP numeric. The top third of the display is replaced with the RESP waveform. 2. To return to the main Vital Signs screen, touch the RESP numeric. The RESP waveform is no longer displayed. To view the SpO2 waveform 1. Touch the SpO2 numeric. The top third of the display is replaced with the SpO2 waveform. 2. To return to the main Vital Signs screen, touch the SpO2 numeric. The SpO2 waveform is no longer displayed. 73 Monitoring the Patient 5.2.5 Motion Artifact If a vital sign cannot be measured due to a motion artifact, the word “MOTION” displays below the vital sign name, and “xx” is displayed in place of the numeric(s). 74 Monitoring the Patient 5.2.6 Taking a NIBP Measurement The industry-standard technique of oscillometry is used for non-invasively measuring systolic blood pressure (SBP) and diastolic blood pressure (DBP). The method is based on the measurement of oscillations through the occluding cuff which is placed on the patient’s upper arm during an NIBP measurement. The pulsatile oscillations are measured using a pressure transducer, and then digitized using a microprocessor. The NIBP algorithm uses the digitized oscillations and applied cuff pressure as input to an empirical model to calculate SBP and DBP. Blood pressure measurements can be affected by the patient’s position and/or physiological condition: • • • The cuff should be at the same level as the patient’s heart. NIBP are not reliable indicators for patients with arterial or frequent premature ventricular beats. Improper cuff size or application may lead to inaccurate readings. This section describes how to take a single NIBP measurement and how to initiate automatic NIBP measurements at various intervals. For patient comfort, when the NIBP is set to manual, remove the Cuff and the Cuff Module from the patient's arm. Once removed, disconnect the Cuff Module from the Monitor between measurements. Store the Cuff and Cuff Module in a convenient location. The ViSi Mobile Monitor should never be used to measure the NIBP of one patient while the Monitor is simultaneously connected to another patient. Do not attempt to take NIBP measurements with the ViSi Mobile Monitor while the patient is undergoing cardio-pulmonary bypass. Do not attempt to take NIBP measurements with the ViSi Mobile Monitor while the patient is being treated with an intra-aortic balloon pump or left ventricular assist device. Periodically observe the patient’s arm for signs of impaired circulation, which may be a result of measurements made too frequently. Loosen or remove the ViSi Mobile Disposable Cuff if signs and/or symptoms of prolonged impaired circulation are evident. If you are uncertain of the reliability of an NIBP measurement, repeat the measurement. If the reading is still suspect, use another method to measure the blood pressure. The ViSi Mobile Disposable Cuff should be snug enough to support the Cuff Module while not impairing circulation when deflated. Note: The ViSi Mobile Cuff Module cannot be used with the auscultatory method of measuring NIBP. 75 Monitoring the Patient To take a single NIBP measurement 1. Apply the Cuff and Cuff Module. See Applying the ViSi Mobile Cuff Module and Disposable Cuff on page 61. After the Cuff Module has been connected to the Monitor, the NIBP vital sign numerics (Systolic and Diastolic) display as “xx”, indicating no measurement has been taken. 2. Touch Start NIBP to start a measurement. After a few seconds to zero and calibrate the barometric pressure, the Cuff begins inflating. An inflation pressure indicator bar, located to the left of the NIBP numerics, increases/decreases in height as the pressure increases/decreases in the Cuff. The actual cuff pressure is displayed under the NIBP label. Once the Cuff begins to inflate, the Start NIBP button changes to Stop NIBP. Note: If unexpected readings are encountered, confirm the correct application of the ViSi Mobile Disposable Cuff (see page 61). If unexpected readings persist, have maintenance performed as described in the Technical Reference Manual. The performance of the automated sphygmomanometer may be affected by extremes of temperature, humidity and altitude. See “Specifications” on page 125. 76 Monitoring the Patient Upon completion of a successful measurement, the Systolic and Diastolic measurements are displayed in white. The time of the measurement is displayed below the NIBP label. If there is no other heart rate/pulse rate source (i.e. Thumb Sensor or Chest Sensor Cable are not connected to the Monitor), then a one-time PR from the NIBP measurement is displayed next to the NIBP measurement for 30 seconds. Time of Measurement Systolic Diastolic Note: If the NIBP measurement was unsuccessful, the Cuff Module automatically retries to measure the blood pressure. A maximum of 3 attempts will be made. If the failure is due to a cuff leak or cuff occlusion, there is no retry and the LEAK or OCCL message appears on the screen directly below the NIBP label. NIBP numerics fade and shrink in size after 30 seconds to indicate that the reading is not recent.

Alarms 6.1 Introduction The ViSi Mobile Monitoring System provides a comprehensive alarm system that alarms on changes to the patient’s physiologic status (alarms) and technical alarms (alerts). The system provides default alarm limits for physiological alarms. The clinician can manually manage the alarm limits for each patient to provide individualized care. Technical alarms (alerts) are provided to notify the clinician of situations that may impede the ability to monitor your patient. 6.1.1 System Alarm Management During the installation of the ViSi Mobile Monitoring System, alarm configurations may be modified to conform to the alarm policies set by the clinical care unit. General Alarm Management Rules The following general alarm management rules pertain to the ViSi Mobile Monitoring System: • • • All ViSi Mobile Monitoring System alarms conform to IEC 60601-1-8. Alarms and alerts originate from the ViSi Mobile Monitor (worn by the patient). Silencing/acknowledging a patient’s alarm or alert suspends the audio tones for up to 2 minutes. When a new alarm/alert occurs during the 2 minute silenced/acknowledged period, the new alarm/ alert will be immediately annunciated. Note: When the clinician silences/acknowledges an alarm/alert, all active alarms/alerts in progress will also be silenced/acknowledged for the 2 minutes. The clinician does not need to silence/ acknowledge each alarm/alert individually. • Alarm annunciation may be turned off for an indefinite period of time. This disables the annunciation of alarms and alerts on both the ViSi Mobile Monitor and the Remote Viewer for the “off” duration. Turning the alarms off must be done directly from the ViSi Mobile Monitor (worn by the patient), however, alarms may be turned back on from either the ViSi Mobile Monitor or the Remote Viewer. • Alarm annunciation may be paused for 2 minutes. This disables the annunciation of alarms and alerts on both the ViSi Mobile Monitor (worn by the patient) and the Remote Viewer for the paused duration. Pausing the alarms must be done directly from the ViSi Mobile Monitor (worn by 89 Introduction the patient), however, alarms may be resumed from either the ViSi Mobile Monitor or the Remote Viewer. Note: When the annunciation of alarms/alerts has been turned off or paused, certain important alarms and alerts will continue to annunciate (known as break-through alarms and alerts). These are generally equipment alerts that inhibit the ability to monitor the patient appropriately. Note: When alarms/alerts are paused, alarms/alerts currently in progress will no longer be annunciated. The annunciation of any new alarms/alerts will be disabled for the 2 minute duration. Note: When alarms/alerts are silenced/acknowledged, the audio tone will be silenced. Any new alarms/alerts occurring during the 2 minute silenced/acknowledged duration will be immediately annunciated. In Network Rules When the ViSi Mobile Monitor is in network and connected to the ViSi Mobile Remote Viewer: • When the ViSi Mobile Monitor is connected to the Remote Viewer, the audio alarm and alert tones will be deferred from the Monitor to the Remote Viewer, for a pre-configured length of time. Note: Audio tones for life threatening alarms will not be delayed. • Alarms/alerts may be silenced/acknowledged from either the ViSi Mobile Monitor or Remote Viewer. Note: Silencing/acknowledging a life threatening alarm directly from the ViSi Remote Viewer will only silence/acknowledge the alarm on the Remote Viewer. To silence/acknowledge the life threatening alarm on the ViSi Mobile Monitor, the clinician must silence/acknowledge the alarm directly from the Mobile Monitor (worn by the patient). • When alarm annunciation has been turned off, alarm annunciation may be turned back on from either the ViSi Mobile Monitor or Remote Viewer. Turning alarm annunciation off can only be done directly from the ViSi Mobile Monitor (worn by the patient). • When alarm annunciation has been temporarily paused, alarm annunciation may be resumed from either the ViSi Mobile Monitor or Remote Viewer. Pausing alarm annunciation can only be done directly from the ViSi Mobile Monitor (worn by the patient). 90 Physiological Alarms (Alarms) / Technical Alarms 6.2 Physiological Alarms (Alarms) / Technical Alarms (Alerts) Summary 6.2.1 Responding to Alarms/Alerts Silencing Audible Alarms/Alerts from ViSi Remote Viewer Where to Respond to Alarm Priority Type of Alarm Life Threatening Silence Button Audio Tones Remote Viewer (At Clinician’s Station) Mobile Monitor (At Patient) Silenced at the Remote Viewer for 2 minutes.

The patient wearing the ViSi Mobile Monitor has moved outside of the wireless network area. Move the patient back into the wireless network area. On the ViSi Mobile Remote Viewer, all patients have disappeared from the Care Unit area. The network cable has been disconnected from the ViSi Mobile Remote Viewer. Reconnect the network cable to the Remote Viewer. 8.7.2 Alarms and Alerts If you test the speaker at the ViSi Mobile Remote Viewer and the tone does not sound or it is not loud enough, immediately contact a biomedical engineer. The test indicates how alarm and alert tones sound at the Remote Viewer. If the sound is inadequate, clinicians could miss alarms and alerts. Problem Explanation I acknowledge an alarm at the ViSi Mobile Remote Viewer, but the audio tone still occurs at the ViSi Mobile Monitor. • • An alarm occurs, but the audio tone stops before I acknowledge it. • • Life-Threatening alarms latch at the ViSi Mobile Monitor until they are acknowledged there, even if the alarm condition resolves. Certain alerts (such as a sensor being disconnected) continue to sound at the ViSi Mobile Monitor until you acknowledge the alert at the Monitor. If an alarm or alert condition resolves before it is acknowledged, the audio tones stops. If the alarm condition was a high-level severity, the alarm message will remain visible (in gray) for five minutes. I stop monitoring a patient at the ViSi Mobile Monitor, according to procedure, but a MONITOR STOPPED alert still appears on the ViSi Mobile Remote Viewer. The alert informs all clinicians who are remotely monitoring the patient that monitoring has stopped. Acknowledge the alert to remove the patient from the care unit. My patient had a vital sign alarm. I did not acknowledge the alarm, but I removed the sensor from the patient. The vital sign alarm continued. You must acknowledge the vital sign alarm, even if the sensor is removed. 122 General Troubleshooting Problem Explanation An alert with the icon and PATIENT TAMPERING message occurred. What does it mean? Someone has unsuccessfully tried to log in to the ViSi Mobile Monitor five or more times. The visual indications go away after the alert is acknowledged and after a clinician successfully logs in at the Monitor. When an alarm or alert occurs, the audio annunciation is heard on the ViSi Remote Viewer, but there is no audio on the ViSi Mobile Monitor. Most alarms and alerts will audible annunciate at the ViSi Remote Viewer before they audibly annunciate at the ViSi Mobile Monitor. This is to minimize disturbing the patient. Sometimes if more than one alarm or alert occurs for a patient at the same time, one or more of the messages don’t show. • • • • If the alarms or alerts are the same severity level, the messages will cycle through. Messages for alarms or alerts that are at a lower severity level will not be displayed. If alarms and alerts occur simultaneously, only messages associated with the alarms will be displayed. Other visual indications usually show for lower level alarms and alerts. Sometimes I acknowledge an alarm or alert, and all alarm or alert indications go away. The audio tone never returns. Some alarms and alerts are acknowledged permanently. At the ViSi Mobile Monitor, I set all alarming to OFF, or I set all alarming to PAUSED. But some alarms and alerts continue to be annunciated. Some important alarms and alerts (such as sensor being disconnected) will continue to annunciate even when all alarms are turned off, or paused. When an alarm or alert occurs, the ViSi Mobile Remote Viewer does not sound an audio tone, or the tone is not loud enough. • • • The ViSi Mobile Remote Viewer displays a CONNECTIVITY LOST alert, what does it mean? Some alerts do not have an audio tone. When an audio tone is associated with an alarm or alert, the Speaker Test button will animate. When an audio tone is expected, but not present (or not loud enough), immediately contact a Bio Med. The speaker volume for the ViSi Mobile Remote Viewer can be tested at any time (see section ViSi Remote Viewer Audio Test on page 67). The ViSi Mobile Monitor is no currently connected to the network. 123 ViSi Mobile Remote Viewer 8.8 ViSi Mobile Remote Viewer 8.8.1 Setting Alarm Limits Problem Explanation When I try to adjust individual limits in the Alarm Settings pane, I cannot go past certain limit values. You cannot set limits beyond the care unit alarm limits. When I adjust an upper limit, the lower limit also changes, or vice versa. If you adjust a vital sign limit to equal the opposite limit, the opposite limit adjusts. Upper and lower limits for a vital sign cannot be the same value. The alarm limits on the ViSi Mobile Monitor and the limits at the ViSi Mobile Remote Viewer do not match. The alarm limits were set on the ViSi Mobile Monitor while the Monitor was not connected to the network. The new limits will not be communicated back to the ViSi Remote Viewer until the Monitor reconnects to the network. The alarms were changed on the ViSi Remote Viewer but before the new alarm limits were communicated to the ViSi Mobile Monitor, the Monitor moved out of network. The limits on the Monitor are the operating limits at all times. 124 9.

In the above table, UT (Unit in Test) is the ViSi Mobile Monitoring System. 151 Safety and Performance Tests 9.7.4 Recommended Separation Distance The ViSi Mobile Monitor may be temporarily interrupted by UHF RFID Systems (860-960MHz). Portable and mobile RF communications equipment should be used no closer to any part of the ViSi Mobile Monitor, including cables, than the recommended separation distance calculated from the equation appropriate for the frequency of the transmitter. Field strengths from fixed RF transmitters, as determined by an electromagnetic site survey, should be less than the compliance level in each frequency range. Interference may occur in the vicinity of equipment marked with this symbol: In the following table, P is the maximum output power rating of the transmitter in watts (W) according to the transmitter manufacturer and d is the recommended separation distance in meters (m). Immunity Test IEC 60601-1-2 Test Level ViSi Mobile Monitoring System Compliance Level Electromagnetic Environment Guidance Conducted RF IEC 61000-4-6 3 VRMS 150 kHz to 80 MHz 3 VRMS Recommended separation distance: d = 1.2√P Radiated RF IEC 61000-4-3 3 V/m 80 MHz to 2.5 GHz 3 V/m Recommended separation distance: 80 MHz to 800 MHz 80 MHz to 800 MHz d = 3.5√P 800 MHz to 2.5 GHz d = 2.3√P 2.0 to 2.3 GHz for short radio d = 7.0√P Field strengths from fixed transmitters, such as base stations for radio (cellular, cordless) telephones and land mobile radios, amateur radio, AM and FM radio broadcast and TV broadcast cannot be predicted theoretically with accuracy. To access the electromagnetic environment due to fixed RF transmitters, an electromagnetic site survey should be considered. If the measured field strength in the location in which the ViSi Mobile Monitor is used exceeds the applicable RF compliance level above, the Monitor should be observed to verify normal operation. If abnormal performance is observed, additional measures may be necessary, such as reorienting or relocating the Monitor. These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption and reflection from structures, objects and people. 152 Safety and Performance Tests From Portable and Mobile RF Communication Equipment The ViSi Mobile Monitor is intended for use in an electromagnetic environment in which radiated RF disturbances are controlled. The customer or user of the Monitor can help prevent electromagnetic interference by maintaining a minimum distance between portable and mobile RF communications equipment and the Monitor as recommended below, according to the maximum output power of the communications equipment. In the following table, P is the maximum power output rating of the transmitter in watts (W) according to the transmitter manufacturer and d is the recommended separation distance in meters (m).

Do not expose the equipment to x-ray or strong magnetic fields (MRI). Fast Transients/Bursts The equipment will return to the previous operating mode within 30 seconds without loss of any stored data. 153 Wireless Network Risk Mitigation 9.8 Wireless Network Risk Mitigation Reference: ISO 80001-1 ViSi Mobile System utilizes the Responsible Organization’s wireless IT network to communicate between individual ViSi Mobile Monitors connected to patients and the ViSi Appliance. Physiologic data and alarms originating from the ViSi Mobile Monitors are transmitted over the IT network to the ViSi Remote Viewer where supplemental alarm notification occurs. Reliability of the IT network is essential in ensuring the supplementary alarm notification meets the intended use. Other RF radiating devices (such as high powered RFID readers and Bluetooth devices) that are in close proximity with the ViSi Mobile Monitor may interfer with the Monitor’s wireless communications. During such interference, the Monitor continues to monitor and will alarm locally. If wireless communication is affected when using the Monitor in close proximity with another RF radiating device, move the other device away from the Monitor or discontinue use of the other device. Perform a risk assessment and verification before you implement a change or modification to the IT infrastructure. Changes to IT network configurations can compromise continuous vital signs monitoring and alarm delivery. 9.8.1 Risk Analysis Summary • • • The ViSi Mobile Monitors are the source of all alarms and alerts. The ViSi Remote Viewer provides a supplemental alarm notification. When connectivity is present audio alarms are deferred to the ViSi Remote Viewer. In the event that network connectivity is lost, all audio alarms are annunciated at the ViSi Mobile Monitors. A connectivity lost alert is annunciated at the ViSi Remote Viewer. 9.8.2 Residual Risks Loss of network connectivity will result in failure in supplemental alarm notification to the ViSi Appliance and ViSi Remote Viewer. Management of this risk is the responsibility of the Responsible Organization for the IT Network. This risk is minimized with the following mitigations: Sotera Responsibilities • • Sotera Inc network assessment prior to installation. Sotera Inc verification that the Responsible Organization network meets ViSi Mobile System connectivity requirements at the time of installation. Responsible Organization Responsibilities • • • • 154 Conduct a risk assessment of the IT Network prior to installation and mitigate technical risk. Maintain backup and emergency power resources for ViSi System network components specified in the ViSi Installation Manual (Hardcopy: 95-10061 / CD: 95-10059). Maintain network configuration post installation of the ViSi Mobile System. Notify Sotera prior to modifications to the network, including any configurations changes that could potentially compromise the IT Network as verified at the initial installation of the ViSi System.
