8Chapter 1 General information Welch Allyn Micropaq MonitorUnderstanding the monitor and the FlexNet NetworkThe monitor is intended to operate with an Acuity® Central Station as part of Welch Allyn’s FlexNet network. FlexNet allows multiple devices to communicate through hardwired Ethernet networks and Wireless Local Area Networks (WLANs). The Acuity Central Station provides the primary display and entry of patient data for a patient connected to the monitor.Each patient-worn monitor supports two-way communication with an Acuity Central Station through an access point in the FlexNet network. The access point is a digital radio transceiver that connects to the FlexNet network. During monitoring, the monitor sends the patient data to Acuity. Acuity and the monitor continuously analyze the data. Acuity provides appropriate alarm or alert messages at the Central Station and other network devices such as a hallway message panel and the monitor itself. Acuity also stores the patient data for viewing or report printing.If the monitor is moved out of range or loses communication with the FlexNet network and Acuity, it continues to monitor the patient and display patient data. While not communicating with Acuity, the monitor continues to generate local patient alarms or alert messages. Patient data is not stored and Acuity does not perform waveform analysis or generate arrhythmia messages while the monitor is not communicating with Acuity.When the monitor is returned to within range of the FlexNet network, it automatically reconnects to Acuity.HRSpO280 97FlexNet NetworkMicropaq monitorsAccess PointsTo Other Access PointsTo Other AcuityCentral StationsAcuity Central StationHRSpO280 97HRSpO280 97HRSpO280 97

10 Chapter 1 General information Welch Allyn Micropaq MonitorVisual alarm indicatorAudible alarm indicatorBeeps to indicate a patient alarm, and beeps faster for life-threatening arrhythmia alarms (see ”Patient alarm and equipment alert specifications” on page 56).Beeps to indicate when the equipment needs attention. This beep tone is slower than patient alarm tones (see ”Patient alarm and equipment alert specifications” on page 56).Volume can be configured as high, low, or off (configured at Acuity).Volume can be configured differently for network connection or stand-alone operation (configured at Acuity).Snapshot keyWhen connected to Acuity, pressing this key sends a snapshot of the patient’s numeric and waveform data to the Acuity Central Monitoring System. Depending on how Acuity is configured, this will cause Acuity to print a 21-second snapshot (14 seconds of history, 7 seconds of data after the button is pressed) to the Acuity central station printer. Scroll Up key and Reset Patient Alarm Tone keyScrolls up menus on the display. Resets a silenced patient alarm tone. Green Flashes slowly during normal operation.Red Flashes during patient alarm, remains on continuously when alarms are silenced or suspended.Yellow Flashes during an equipment alert or while not connected to the network.Remains on continuously if the operator suspends an alert at Acuity for 90 seconds or acknowledges (dismisses) a low battery alert from the monitor or Acuity.NoteThe flashing green LED indicates that the monitor is connected to the network but not necessarily connected to a patient. If the monitor is actively monitoring a patient, the green LED indicates no alarms or alerts are detected.NoteSnapshot is the default selection of the monitor. However, the connected monitor will inherit the configuration previously defined by Acuity. For example, if Acuity has defined the Snapshot key to respond with a Nurse Call function and a new monitor is introduced to the system, the Snapshot key definition will remain as Nurse Call.For more information about using the Acuity Central Monitoring System, refer to Acuity Directions For Use (810-1605-XX)

Minimize patient motion whenever possible.WARNING If a disconnected lead is in too close proximity to other electrical devices, it may cause false heart rate readings.WARNING The monitor does not provide internal arrhythmia analysis. Therefore, arrhythmias may cause the monitor to display inaccurate heart rates.WARNING The monitor will show + + + for HR numerics between 301 and 350 beats per minute. Above 350 beats per minute, it may display incorrectly low heart rates, due to intermittent picking of R-waves.WARNING Do not use the monitor in a Magnetic Resonance Imaging (MRI) suite or a hyperbaric chamber. Such use can cause fire or explosion resulting in patient injury and monitor damage.WARNING Pacemaker signals can differ from one pacemaker to the next. The Association for Advancement of Medical Instrumentation (AAMI) cautions that “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.” See “ECG specifications” on page 51 for disclosure of the pacemaker pulse rejection capability of this instrument.
22 Chapter 2 Monitoring Welch Allyn Micropaq Monitor• Even though the monitor contains fully isolated patient-connected circuitry, it has not been specially designed for direct application on a patient’s heart.• Use only with accessories provided or recommended in the Welch Allyn Products and Accessories booklet (810-0409-XX).• Severe artifact and interference (such as defibrillation interference) can cause the waveform to move off the display for a few seconds before it is restored.WARNING For patients with a pacemaker, position the monitor to maintain a minimum 6-inch distance between the monitor and pacemaker. Immediately turn the monitor off and provide appropriate patient care if you have any reason to suspect that the monitor is interfering with the pacemaker. The Health Industry Manufacturers Association recommends this minimum 6-inch distance between a hand-held wireless radio and a pacemaker, which is consistent with the independent research by, and recommendations of, Wireless Technology Research.WARNING High-intensity radio frequency (RF) energy from external sources, such as an improperly connected electrosurgical unit, can induce heat into electrodes and cables which can cause burns on the patient. Reading errors and damage to equipment may also result. This hazard can be reduced by (1) avoiding the use of small ECG electrodes, (2) selecting ECG electrode attachment points remote from the surgical site and from the electrosurgical return electrode, (3) using electrosurgical return electrodes with the largest practical contact area, and (4) assuring proper application of the electrosurgical return electrode to the patient. WARNING Verify patient mode at Acuity. Incorrect patient mode may result in inaccurate heart rates and inappropriate alarm settings.WARNING To help prevent injury, use the provided garment clips to route the ECG cables away from the patient’s head.WARNING Use of ECG cables with loose or faulty detachable lead wires may cause erratic behavior of the ECG waveform due to intermittent ECG lead wire connections.WARNING To ensure patient safety, the conductive parts of the ECG electrodes (including associated connectors) and other patient-applied parts should not contact other conductive parts, including earth ground, at any time.Caution To protect the monitor from damage during defibrillation, for accurate ECG information, and for protection against noise and other interference, use only ECG electrodes and cables specified or supplied by Welch Allyn (these cables have the required current-limiting resistors). Follow recommended application procedures.Caution Do not use an ECG cable longer than 10 feet (3 meters). If the nominal length of the ECG cable, including extensions, exceeds this length, the monitor is not guaranteed to meet published electromagnetic compatibility (EMC) performance specifications.
Directions for Use Chapter 2 Monitoring 23Perform 5-Lead ECG monitoring1. Inspect the ECG cable and replace it if it shows any signs of wear, breakage, or fraying. Plug the cable into the monitor.2. Select electrode sites on the patient.Choose flat areas; avoid fatty or bony areas and major muscles.3. Shave or clip hair from electrode sites, thoroughly clean skin, and lightly rub dry.You may use soap and water, isopropyl alcohol or special skin preparation pads. To avoid allergic reactions to electrodes, refer to the electrode manufacturer’s directions.4. If you are using pre-gelled electrodes, make sure the electrode date is not expired and the gel is intact and not dried out. For best results, use only silver/silver chloride electrodes.If you are using ungelled electrodes, apply a 1/4- to 1/2-inch mound of gel over the electrode contact area.For best product performance and measurement accuracy, do not use stainless steel needle electrodes, squeeze bulb electrodes, or electrodes with dissimilar metals. Due to polarization, such electrodes can generate offsets beyond the monitor’s capabilities. Do not use electrodes from more than one manufacturer on the same patient.5. Attach lead wires to the electrodes before applying them to the patient. Apply the electrodes to the patient in the proper locations.If the monitor detects that some lead wires are not properly connected, the monitor displays a chest diagram and indicates which leads are disconnected.The locations of the circles displayed on the monitor for each lead are fixed, and are not affected by the exact placement of the electrodes on the patient. For example, the C lead can be placed on the patient in any one of the V1-V6 locations desired, but will only be displayed on the monitor in the location shown above.Flashing circle indicates the lead is not connected.Left ArmRight ArmLeft LegRight Leg

After leads are properly connected, confirm that the monitor displays the ECG waveform, heart rate, and other patient data.To change the ECG lead selection, press to display the Main Menu. Then press Scroll Down to highlight ECG LEAD . . . , then highlight ECG 1 or ECG 2 and press to change the lead.3-Lead ECG application with the 5-Lead ECG cableYou can perform 3-lead ECG monitoring in a similar manner as 5-lead ECG monitoring. You may use the 5-lead ECG cable with detachable electrode lead wires, and connect only the lead wires and electrodes for RA, LA, and LL. Refer to the Welch Allyn Product and Accessories booklet (810-0409-XX) for part numbers.Follow these steps:1. Pe r f o r m Step 1 through Step 4 on page 23 as described for 5-lead ECG monitoring.2. Before attaching electrodes to the patient, attach only lead wires for RA, LA, and LL to the 5-lead ECG trunk cable and to the electrodes. Make sure that lead wires for C and RL are DETACHED from the 5-lead ECG trunk cable.3. Apply the electrodes for RA, LA, and LL to the patient in the proper locations.The monitor displays the chest diagram with two circles blinking confirming that the C and RL electrodes are not connected.4. Observe the monitor and visually confirm that within about 30 seconds, the two circles disappear and the monitor displays the ECG waveform, heart rate, and other patient data.Be aware that if you connect the C or RL lead wires to the 5-lead ECG trunk cable and apply the C or RL electrodes to the patient, the monitor defaults to 5-lead ECG monitoring and does not enable 3-lead ECG monitoring. To enable 3-lead ECG monitoring, you must disconnect the ECG cable from the monitor for a few seconds, and then begin this procedure again.NoteBe aware that there are some inherent limitations with this application, especially when compared to 5-lead ECG monitoring. These limitations include the restriction to only one displayed lead, ECG lead II. Because only one displayed lead is available (ECG lead II), factors such as a poor electrode connection at RA, LA, or LL can significantly affect performance. To overcome these limitations, the 5-lead ECG monitoring is preferred.The monitor’s 3-lead ECG monitoring is only available for use with Acuity software versions 6.1 or later.
Directions for Use Chapter 2 Monitoring 25Be aware that only ECG lead II is available for display with the monitor’s 3-lead ECG monitoring. No other ECG lead selections are available.3-Lead ECG application with the 3-Lead ECG cableRefer to the Welch Allyn Product and Accessories booklet (810-0409-XX) for part numbers.Follow these steps:1. Pe r f o r m Step 1 through Step 4 on page 23 as described for 5-lead ECG monitoring.2. Attach lead wires to the electrodes before applying them to a patient.3. Apply the electrodes for RA, LA, and LL to the patient at the proper locations. If the monitor detects one of the lead wires is not properly connected, it will display a chest diagram indicating which lead is disconnected.4. Observe the monitor and visually confirm it displays the ECG waveform, heart rate, and other patient data.Be aware that only ECG lead II is available for display with the monitor’s 3-lead monitoring. No other ECG lead selections are available. The monitor will not detect the presence of a 3-lead cable until two or more of its leads are connected to the patient.3-Lead ECG application with the 3-Lead ECG cable and cable extensionThis combination functions the same way as the 3-lead ECG application with the 5-lead cable. For electromagnetic compatibility (EMC) reasons, do not use an ECG cable and extension cable length of more than approximately 10 feet total.WARNING Do not try to perform this 3-lead ECG monitoring with any 5-lead ECG cable that does not have detachable electrode lead wires as described above. Attempting to perform this procedure with a 5-lead ECG cable which has lead wires cut off or hanging loose and not connected to the patient would present a shock hazard to the patient or clinician.NoteBe aware there are some inherent limitations with this application, especially when compared to 5-lead ECG monitoring. These limitations include the restriction to only one displayed lead, ECG II lead. Because only one displayed lead is available (ECG lead II), factors such as poor electrode connection at RA, LA, or LL can significantly affect performance. To overcome these limitations, the 5-lead ECG monitoring is preferred.The monitor’s 3-lead ECG monitoring is only available for use with Acuity software versions 6.1 or later.
26 Chapter 2 Monitoring Welch Allyn Micropaq MonitorPerform SpO2 monitoringWARNING Oxygen saturation measurements using pulse oximetry are highly dependent on proper placement of the sensor and patient conditions. Patient conditions such as shivering and smoke inhalation may result in erroneous oxygen saturation readings. If pulse oximetry measurements are suspect, verify the reading using another clinically accepted measurement method, such as arterial blood gas measurements on a co-oximeter.WARNING Use only accessories as listed in the Welch Allyn Products and Accessories booklet (810-0409-XX). Use only Masimo accessories and sensors with the Masimo SpO2 option. Use only Nellcor accessories and sensors with the Nellcor SpO2 option. The monitor will only meet the listed specifications when using accessories listed by Welch Allyn.WARNING Use of Masimo LNOP® sensors/cables will not provide protection in accordance with IEC defibrillation standards when used with this device.WARNING Tissue damage can be caused by incorrect application or use of a sensor (e.g., wrapping the sensor too tightly, applying supplemental tape, failing to periodically inspect the sensor site, leaving a sensor on too long in one place). Refer to the Directions for Use provided with each sensor for specific instructions on application and use, and for description, warnings, cautions, and specifications.WARNING Sensors exposed to ambient light while not applied to a patient can exhibit semi-normal saturation readings. Be sure the sensor is securely placed on the patient and check its application often to ensure accurate readings.WARNING Inaccurate measurements may be caused by venous pulsations.WARNING The pulse oximeter can be used during defibrillation, but the readings may be inaccurate for a short time.WARNING The pulse oximeter should NOT be used as an apnea monitor.WARNING A very sudden and substantial change in pulse rate can result in erroneous pulse rate readings. Be sure to validate the patient data and patient condition before intervention or change in patient care.WARNING Interfering Substances: Carboxyhemoglobin may erroneously increase readings; the level of increase is approximately equal to the amount of carboxyhemoglobin present. Methemoglobin may also cause erroneous readings. Dyes, or any substances containing dyes, that change usual arterial pigmentation may cause erroneous readings.
Directions for Use Chapter 2 Monitoring 271. Attach the SpO2 sensor to the patient according to the manufacturer’s directions for use, observing all warnings and cautions.Each SpO2 sensor is designed for application to a specific site on the patient within a certain size range. To obtain optimal performance, use an appropriate sensor and apply it as described in the sensor’s directions for use.If excessive ambient light is present, cover the sensor site with opaque material to block the light. Failure to do so may result in inaccurate measurements. Light sources that can affect performance include surgical lights (especially those with a xenon light source), bilirubin lamps, fluorescent lights, infrared heating lamps, and direct sunlight.If NIBP will be monitored while using SpO2, place the NIBP cuff on a different limb than the SpO2 sensor to help reduce unnecessary SpO2 alarms. For optimal measurements, avoid placing the SpO2 sensor on the same limb as an arterial catheter or intravascular line.Loss of pulse signal can occur if the sensor is too tight, there is excessive ambient light, an NIBP cuff is inflated on the same limb as the sensor, there is arterial occlusion proximal to the sensor, the patient is in cardiac arrest or shock, or the patient has hypotension, severe vasoconstriction, severe anemia, or hypothermia.2. Inspect the SpO2 cable. Replace it if it shows any signs of wear, breakage, or fraying. Plug the cable into the sensor and the monitor.3. After the cable is connected, confirm that the monitor displays SpO2 data within a few seconds.4. If excessive patient movement interferes with measurements, consider the following possible solutions:• be sure the sensor is secure and properly applied• use a new sensor with fresh adhesive backing• select a different type of sensor• move the sensor to a less active siteThe SpO2 system is designed to work satisfactorily during normal patient motion.
