Warnings, Cautions and Notes
12
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.

Warnings, Cautions and Notes
13
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.

Warnings, Cautions and Notes
14
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.
![](/img.php?id=1750411&img=bgf.png)
Warnings, Cautions and Notes
15
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 pre-
set limits. Once Auto Set is selected, review the newly calculated alarm limits carefully
before deciding to confirm or cancel the new alarm limits.

Warnings, Cautions and Notes
16
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. The test indicates
how alarm and alert tones sound at the Remote Viewer. If the sound is inadequate,
clinicians could miss alarms and alerts.
User Maintenance
To avoid contaminating or infecting personnel, the environment or other equipment,
make sure you disinfect and decontaminate the ViSi Mobile Monitoring System
components appropriately before disposing of them in accordance with your country’s
laws for equipment containing electrical and electronic parts.

2. 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.

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.
![](/img.php?id=1750411&img=bg26.png)
Overview of Clinical Features
38
RESP is determined from the frequency of the respiration (chest wall motion). The respiration channel can
detect the absence of RESP.
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.
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.
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 implementing therapy based on the skin temperature
measurement, verify the measurement using another clinically acceptable
method of core temperature measurement.
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.

Display Screens
39
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.
Note: When the yellow dot is displayed on the screen, it indicates the Monitor will measure RESP

• The Monitor is not in the Charger
• No sensors are connected to the Monitor
Note: When in Hibernation, the power indicator blinks approximately every 9 seconds. The power
indicator color is reflective of the battery status: “Green” indicates there is sufficient battery
charge for at least two hours of monitoring; “Yellow” indicates the battery charge is depleted
and there is less than 2 hours of monitoring available; and “Red” indicates the battery
charge is depleted and there is less than 30 minutes of monitoring available. When the
power indicator stops blinking, the battery charge is empty.
Note: Connecting a sensor to the Monitor displays the Vital Sign screen. There will be a brief delay
before the Vital Sign screen is displayed to allow the Monitor’s self test to complete.

4. 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.
![](/img.php?id=1750411&img=bg2e.png)
Preparing for a New Patient
46
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.
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:
• 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

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)
•SpO
2
PR (from the Thumb Sensor)
•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.

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.

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.
4.3.2 Applying Sensors
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.
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.
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.

The Thumb Cradle is designed to hold the Thumb Sensor in place securely without impairing
circulation.
4. Check the patient’s thumb for good color and circulation to ensure that the Thumb Sensor has not
restricted circulation.
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.
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.
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.
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.

4.3.4 Applying the ViSi Mobile Chest Sensor Cable and ECG Elec-
trodes
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.
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.

4.3.5 Applying the ViSi Mobile Cuff Module and Disposable Cuff
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.
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.

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.
![](/img.php?id=1750411&img=bg42.png)
Monitoring the Patient
66
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.

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.
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.

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.
Note: The ViSi Mobile Cuff Module cannot be used with the auscultatory method of measuring
NIBP.
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.
![](/img.php?id=1750411&img=bg4c.png)
Monitoring the Patient
76
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.

Monitoring the Patient
77
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.
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.
NIBP measurements that are older than 30 minutes are no longer displayed.

Module, while not impairing circulation when deflated.
Use care when using automatic cuff inflation for prolonged periods on
unconscious or semi-conscious patients since the patient may not be able to
alert the clinician to any pain he/she may be experiencing. Pressing the
“Stop NIBP” button interrupts the NIBP measurement and deflates the cuff.

6. 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
Introduction
90
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).

6.6 Manage Alarm Limits
Alarm limits for each vital sign parameter are predefined and turned on automatically whenever a sensor is
connected to the patient and to the Monitor. Sometimes it is desirable to adjust the alarm limits to meet a
patient’s monitoring requirements.
The Auto Set function sets alarm limits based on the current vital signs measurements for all connected
sensors. If the alarms are turned off prior to initiating the Auto Set process, the alarms are turned back on
when the new alarm limits are confirmed.
To change alarm limits using Auto Set
1. Touch Menu on the Vital Signs screen.
2. Touch Alarms Settings.
The Patient Alarms Settings screen appears.
Note: Alarm limit settings are only displayed for the currently monitored vital signs.
3. Touch Auto Set.
Alarm limits for all currently monitored vital signs are recalculated based on the current vital
signs measurements. The Confirm New Alarm Limits screen appears.
Once new alarm limits are confirmed, they cannot be changed back to the
original pre-set limits. Once Auto Set is selected, review the newly
calculated alarm limits carefully before deciding to confirm or cancel the new
alarm limits.

8.7 General Troubleshooting
8.7.1 Connectivity Lost
8.7.2 Alarms and Alerts
Problem Potential Cause Solution
On the ViSi Mobile Remote
Viewer, “XX” appears where all
vital sign measurements should
be displayed.
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.
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.
• 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 discon-
nected) continue to sound at the ViSi Mobile
Monitor until you acknowledge the alert at the
Monitor.
An alarm occurs, but the audio tone stops before I
acknowledge it.
• 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.
![](/img.php?id=1750411&img=bg7b.png)
General Troubleshooting
123
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 dis-
played.
• 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.
• 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 Remote Viewer displays a
CONNECTIVITY LOST alert, what does it mean?
The ViSi Mobile Monitor is no currently connected to
the network.

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.

9.7.4 Recommended Separation Distance
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.
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).
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.
The ViSi Mobile Monitor may be temporarily interrupted by UHF RFID
Systems (860-960MHz).

Wireless Network Risk Mitigation
154
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.
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
• 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. For support contact Sotera Wireless or an authorized Sotera Wireless representative in
your area.
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.
