inaccurate SpO2 readings or damaged equipment.
16
Warnings
The ViSi Mobile Thumb Sensor is intended for use on the patient’s thumb, index and
middle finger for SpO2 measurements; however, cNIBP can only be measured while on
the patient’s thumb.
Warnings
Inspect the patient’s skin at the sensor site per your facility’s protocol. If the skin surface
has been compromised, reposition the ViSi Mobile Thumb Sensor or move the Thumb
Sensor to the patient’s other thumb. If the thumb sensor is moved to the other thumb,
move the other sensors as well.
Ensure that the ViSi Mobile Thumb Sensor is securely fastened. A Thumb Sensor that
is wrapped too tightly or too loosely can adversely affect SpO2 measurement.
The Thumb Wrap should securely hold the ViSi Mobile Thumb Sensor in place without
impairing circulation. Immediately loosen the Thumb Wrap if the patient complains of
pain, tingling, or numbness in the affected thumb.
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”.
ViSi cNIBP has not been evaluated in patients with pacemakers that pace the ventricle.
ViSi’s NIBP may be used instead.
After monitoring has been stopped on the ViSi Mobile Monitor, and the patient has been
removed from the Remote Viewer, this action cannot be undone. Once removed, the
patient’s monitoring session data will no longer be available on the Remote Viewer.
A qualified clinician must always be in direct view of the ViSi Mobile Remote Viewer. If
the Remote Viewer display is blank, contact your biomedical engineer 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, Inc. 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.
17
Warnings
Perform a risk assessment and verification before implementing 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.
ViSi Mobile blood pressure measurements (NIBP and cNIBP) have not been clinically evaluated in the presence of atrial or ventricular arrhythmias. Use alternative BP methods if these
arrhythmias are present.
18
Warnings
Chest Sensor: ECG, Respiration, Temperature (Skin)
Use all of the same type of high quality ECG electrodes on the patient. Mixing ECG
electrode types can adversely affect ECG monitoring.
Avoid placing the ViSi Mobile Cable Securements and ECG electrodes over areas of
abrasions, irritation, or other sensitive areas. If possible, remove, reposition, and
replace ECG electrodes and Cable Securements if the patient complains of pain/itching
at the sites.
The ViSi Mobile Monitor does not provide automated arrhythmia analysis. As a result,
certain arrhythmias may cause the Monitor to display variable heart rates. If frequent
arrhythmias are suspected, their presence should be confirmed by visual observation of
the ECG waveform or another method, such as a 12-lead ECG.
The ViSi Mobile Monitor does not provide 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.
Warnings
Impedance pneumography for the determination of respiration (RESP) is not
recommended for use in the presence of mechanically induced, high frequency
ventilation.
19
Warnings
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.
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. Recommend using the ViSi Mobile
Monitoring System on the opposite arm.
ViSi Mobile NIBP measurements (1-time measurements or continuous measurements)
have not been clinically evaluated in the presence of atrial or ventricular arrhythmias.
Use alternative BP methods if these arrhythmias 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 conditions, including direct sunlight, may interfere with the
performance of the ViSi Mobile Thumb Sensor.
Warnings
Low perfusion, electrosurgical devices, dysfunctional hemogolobin, the presence of
certain dyes and inappropriate positioning of the ViSi Mobile Thumb Sensor may result
in erroneous measurements.
20
Warnings
Alarms / Alerts
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 Auto Set is selected (on the ViSi Mobile Monitor), review the newly calculated
alarm limits carefully before deciding to confirm or cancel the new alarm limits. Once
new alarm limits are confirmed on the ViSi Mobile Monitor, they cannot be changed
back to the original pre-set limits from the ViSi Mobile Monitor. Use the ViSi Mobile
Remote Viewing Device to change the alarm limits back to the original pre-set limits.
When the ViSi Mobile Monitor is not connected or loses wireless connection to the ViSi
Mobile Appliance, the ViSi Mobile Remote Viewer does not receive patient alarms or
alerts from the ViSi Mobile Monitor.
When the last source of monitoring is lost due to equipment (such as thumb sensor off,
ECG leads off, all sensors disconnected) the visual annunciation of the alert will not
have an audible component.
Line isolation monitor transients (artifacts) 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 when it 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.
When testing the speaker at the ViSi Mobile Remote Viewer, you are testing how the
alarm and alert tones will sound at the Remote Viewer during typical operation. If the
volume is inadequate, clinicians could miss alarms and alerts. During testing, if the tone
does not sound or it is not loud enough, adjust the speaker volume.If the sound is still
not loud enough, immediately contact a biomedical engineer.
The ViSi Power Pack Alarms/Alerts DO NOT audibly annunciate on the ViSi Mobile
Monitor or the Remove Viewing Device.
Warnings
If the ViSi Mobile Monitor displays a “Battery Pack Fault” , “Electric Shock”, or “Monitor
Too Hot” message, disconnect the Power Pack immediately.
21
Warnings
User Maintenance
To avoid contaminating or infecting personnel, the environment or other equipment, make
sure to disinfect and decontaminate the ViSi Mobile Monitoring System, Thumb Sensor and
disposables appropriately before disposing of them in accordance with your country’s laws
for equipment containing electrical and electronic parts.Wireless Communications
When the ViSi Mobile Monitor is not configured to connect to the facility’s network or
loses wireless connection to the ViSi Mobile Appliance, the ViSi Mobile Remote Viewer
does not receive patient alarms or alerts from the ViSi Mobile Monitor.
All wireless devices are susceptible to radio frequency interference that can disrupt
connectivity. If excessive ViSi Mobile Monitoring System disconnections are observed,
notify your biomedical engineer. Excessive disconnections can cause interrupted
patient monitoring; disconnections must be investigated and corrected.
Other RF radiating devices (such as high powered RFID readers and Bluetooth
devices) that are in close proximity with the ViSi Mobile Monitor may interfere 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.If you have any concerns
regarding a cyber security breach or vulnerability, contact Sotera Wireless, Inc. or an
authorized Sotera Wireless, Inc. representative in your area.
Off-The-Shelf (OTS) Software
The use of any software other than those specified in this manual will violate the safety,
effectiveness and design controls of this medical device and such use may result in an increased
risk to users and patients.
22
Cautions
2.3 Cautions
Intended Use
Federal (U.S.A.) law restricts the ViSi Mobile Monitoring System and Power Pack to the
sale, distribution, or use by, or on the order of a licensed medical practitioner.
The effectiveness of the ViSi Mobile Monitoring System’s blood pressure monitoring
has not been established in pregnant, including pre-eclamptic, patients.
General
Placing the ViSi Mobile Monitor into the Charger when the “All Sensors Disconnected”
alert is displayed will result in the patient’s monitoring session being stopped. It is
recommended that you follow the correct stop/pause monitoring flows.
When monitoring has been paused, monitoring may only be resumed using the same
ViSi Mobile Monitor. If you place the ViSi Mobile Monitor into the Charger with other
Monitors, label the Monitor so that is can be identified when monitoring is to be
resumed.
Moving the ViSi Mobile Monitor out of the network range will break the radio link,
immediately stopping communication of patient vital signs data to the ViSi Mobile
Remote Viewer.
When the wireless connector symbol is yellow, the ViSi Mobile Monitor is unable to
connect to the ViSi Mobile Remote Viewer (via the ViSi Mobile Appliance).
Only the ViSi Power Pack should be placed into the accompanying cradle.
To avoid damage, the ViSi Power Pack should only be connected to the ViSi Mobile®
Monitor.
Monitoring
The accuracy of cNIBP is dependent on the initial cuff calibration. Use good clinical
practice to confirm cNIBP accuracy before initiating or treating a patient.
The accuracy of the cNIBP measurement cannot be relied upon in patients with a BMI
greater than 35.
Due to cNIBP signal averaging, there is a time delay of up to 120 seconds between the
instantaneous blood pressure reading and the displayed reading.
The ViSi Mobile Monitoring System accuracy claim (mean error of ≤ ±5 mmHg and a
std. dev. of ≤ 8 mmHg) is not met when the subject is in a semi-Fowlers position
(inclined more than 30 degrees from horizontal).
23
Cautions
2-way radios may cause waveform distortion when placed within 1 foot of the ViSi
Mobile Monitor.
Some brands of television may cause temporary waveform distortion and data loss when placed
within 6 feet of the ViSi Mobile Monitor.
Safety
The ViSi Mobile Monitoring System or Power Pack have not been tested in the
presence of flammable anesthetics or other flammable agents in combination with air,
nitrous oxide, or oxygen-enriched environments.
Do not use a ViSi Mobile Monitor, its components, Power Pack or other accessories
that appear damaged. Inspect all reusable components for damage before each use.
Do not attempt to connect any patient worn component, ViSi Chest Sensor or ViSi
Mobile Cuff Module, or ViSi Power Pack to an electrical outlet of any kind.
A component that has been dropped or severely abused should be checked by qualified
service personnel before use on a patient.
The ViSi Mobile Monitoring System or Power Pack are not intended for home use.
Do not use the ViSi Mobile Monitoring System or Power Pack to monitor a patient in a
wet environment, such as a shower.
Explosion Hazard. Do not use in the presence of a flammable anesthetic mixture with
air, or with oxygen or nitrous oxide.
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.
Consult your Biomed department or vendors for assistance in identifying EMC
compliance status of other medical devices when using the ViSi Mobile Monitoring
System or Power Pack.
Using accessories other than those specified may result in increased electromagnetic
emission or decreased electromagnetic immunity of the monitoring equipment.
Changes in posture and arm height can affect ViSi cNIBP accuracy. If the cNIBP
measurement is questionable, retake the measurement. Ideally recalibrate in the same
position as the initial calibration.
Cautions
The accuracy of the cNIBP measurement cannot be relied upon in patients with a BMI
greater than 35.
24
Cautions
Due to cNIBP signal averaging, there is a time delay between the instantaneous blood
pressure reading and the displayed reading.
You should manually recalibrate cNIBP after the administration of an IV vasoactive drug
or a new oral vasoactive drug. The Calibrate cNIBP alert will not be displayed.
If using the ViSi Mobile Monitor with any other monitor on the same patient, check that
each monitor does not interfere with the operation of the other. If interference is
detected, remove one or more of the sensors until there is no longer any interference.
Service / Maintenance
If the ViSi Mobile Monitor detects an unrecoverable problem, an error message
containing the error number is displayed. Remove the Monitor from use and report the
error to Sotera Wireless, Inc Customer Service.
When the ViSi Mobile Monitor is in the Charger and a charging alert occurs, remove the
Monitor from service.
General maintenance of the ViSi Mobile Monitoring System should be conducted at the

3.3.4 ViSi Mobile Cuff Module
The Cuff Module is used to take NIBP measurements and to initiate the cNIBP calibration. The Cuff
Module plugs into any one of the connectors on the flat end of the Wrist Cradle.
For ease of use, the Monitor features three interchangeable plug-in sites for the Chest Sensor, Cuff Module,
and optional ViSi Power Pack. See “ViSi Power Pack” on page 207.
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 during Cuff inflation.

4.3 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, NIBP and
TEMP. The ECG, SpO2, and RESP. Waveforms are viewable on demand. NIBP can be measured as a onetime measurement, automatically at programmed intervals or continuously.
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 and ViSi Mobile Cuff Module. The Chest Sensor measures
the ECG/HR (with a 3 lead-wire or 5 lead-wire), RESP, and TEMP.
4.3.1 ECG Monitoring and Heart Rate (HR) Monitoring
With the 3 lead-wire Chest Sensor, the Monitor continuously monitors Lead II.
With the 5 lead-wire Chest Sensor, 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.
4.3.2 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 II position.
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.
Note: Respiration rate monitoring is an optional feature that requires an additional license key.
47
Overview of Clinical Features
4.3.3 Skin Temperature (TEMP) Monitoring
TEMP continuously measures skin temperature using the sensor located on the underside of the Chest
Module. The sensor 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 CableChest Sensor on page 72.
Note: Skin temperature is not synonymous with core body temperature or temperature measured
using the 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 making clinical decisions based on the skin temperature
measurement, verify the measurement using another clinically acceptable
method of core temperature measurement.
4.3.4 Pulse Oximetry (SpO2 and Pulse Rate) Monitoring
The Pulse Oximetry channel non-invasively and 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 heart rate source from an ECG, the pulse rate can be measured and displayed from the
SpO2 channel.
When turned on, the tone pitch of the heart beat will change with the level of oxygen saturation. A higher
pitch is associated with higher SpO2 levels.
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 conditions, including direct sunlight, may interfere with
the performance of the ViSi Mobile Thumb Sensor.
Low perfusion, electrosurgical devices, dysfunctional hemogolobin, the
presence of certain dyes and inappropriate positioning of the ViSi Mobile
Thumb Sensor may result in erroneous measurements.
4.3.5 NIBP Monitoring
The ViSi Mobile Cuff Module is intended for measuring arterial blood pressure (systolic, diastolic and
MAP) using a Cuff. Measurements may be initiated manually (one at a time), automatically at selectable
predefined intervals of 5, 10, 15, 30, 60, 90 and 120 minutes or continuously.
48
Overview of Clinical Features
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
Note: To measure continuous non-invasive blood pressure (cNIBP), the Cuff Module is only
required for the initial inflation to determine the Pulse Arrival Time (PAT) and for periodic
recalibrations.
Avoid touching the ViSi Mobile Disposable Cuff during cuff inflation as it may
disrupt the measurement.

5.2.2 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 in
the Securement)
Chest Module
(on Chest Sensor in
the Securement)
(Temperature probe on the
back side of the Chest
Module must be placed
against the patients skin)
Cuff Module
(Applied to upper arm)
Monitor
(in Wrist Cradle)
Thumb Sensor
(in thumb wrap)
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 96.
58
Preparing for a New Patient
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
Selecting the appropriately sized Cuff (from the Disposable 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 sensor. 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).
5.2.3 Selecting Vital Signs to Monitor
The following vital signs may be monitored:
•
•
•
Chest Sensor (one or seven simultaneous leads, using the 3 lead-wire or 5 lead-wire Chest Sensor
respectively)
 HR (from the ECG)
 RESP (optional)
 TEMP (Skin Temperature)
Thumb Sensor
 SpO2
 PR (from the Thumb Sensor)
Cuff Module (single measurement, automatically at set intervals or continuously)
 SYS
 DIA
 MAP
 PR (from NIBP)
5.2.4 Selecting the ViSi Mobile Chest Sensor
The Chest Sensor provides the sensors to monitor the ECG, HR, RESP (optional), and TEMP.
Note: The skin surface temperature sensor 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 that best suits the monitoring needs of your patient:
•
•
The 3 lead-wire Chest Sensor monitors Lead II, or the MCL configuration.
The 5 lead-wire Chest Sensor 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.
59
Preparing for a New Patient
5.2.5 Selecting the ViSi Mobile Disposable Kit
The System’s disposable components, including the Cuff are contained in the Disposable Kit. The
Disposable Kits are designated as S, M, M+, L 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.
Cuff / Disposable Kit Size
Arm Circumference (cm)
Adult S
20 – 26
Adult M / M+
25 – 34
Adult L / L+
32 – 43
5.2.6 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. Review the large battery icon in the center of the screen.
The battery color should be interpreted as follows:
•
•
•
60
When the battery is green, the battery is at least 90% charged.
When the battery is yellow, the battery is charged between 40% and 90%.
When the battery is red, the battery charge is less than 40%.
Preparing for a New Patient
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
Note: When the red bar is displayed on the screen, it indicates the Monitor will measure
continuous blood pressure (cNIBP) when a Chest Sensor and Thumb Sensor are connected
to a Monitor.
Note: When the yellow dot is displayed on the screen, it indicates the Monitor will measure RESP
when a Chest Sensor is connected to a Monitor.
Note: cNIBP and RESP measurements are not available as part of the default set of vital sign
measurements and must be purchased separately.
61
Preparing for a New Patient
To check the battery charge of the Cuff Module
Press the 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.

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 Disposable Kit (S, M, M+, L or 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) indicates paced
events. In the case of biventricular pacing (CRT), two vertical dashed lines occur before the QRS.
Note: Vertical dashed lines from pacemaker stimulus pulses may occur. These are not counted as
heartbeats, as defined by the pacer pulse rejection specification. See Chapter 10.
Specifications on page 161.
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.
ViSi cNIBP has not been evaluated in patients with pacemakers that pace
the ventricle. ViSi’s NIBP may be used instead.
Only use the ViSi Mobile Chest Sensor CableChest Sensor
provided by Sotera Wireless, Inc. for the ViSi Mobile Monitoring
System. The Chest Sensor CableChest Sensor 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. Using non-approved Thumb
Sensors may result in inaccurate SpO2 readings or damaged equipment.
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. Dispose of
the components and any packaging material after use per your facility’s
policy or national requirements.
The ViSi Mobile Monitor, Thumb Sensor, Cuff Module, and the Chest
Sensor CableChest Sensor must all be connected to the same arm for the
System to function correctly.

5.3.2 Applying Sensors
The ViSi Mobile Monitor, Thumb Sensor, Cuff Module, and the Chest Sensor
CableChest Sensor 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 time 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.
5.3.3 Applying the ViSi Mobile Thumb Sensor
The ViSi Mobile Thumb Sensor is intended for use on the patient’s thumb,
index and middle finger for SpO2 measurements; however, cNIBP can only
be measured while 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 Wrap from the Disposable Kit.
2. Insert the Thumb Sensor into the Thumb Wrap such that the sensor optics are pointing away from
the Thumb Wrap.

Wrap.
4. Place the Thumb Sensor at the base of the thumb and secure it with the Thumb Wrap.
The Thumb Wrap 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 tightly or too loosely can adversely affect SpO2
measurement.
Inspect the patient’s skin at the sensor site per your facility’s protocol. If the
skin surface has been compromised, reposition the ViSi Mobile Thumb
Sensor or move the Thumb Sensor to the patient’s other thumb. If the thumb
sensor is moved to the other thumb, move the other sensors as well.
5. Check the patient’s thumb for good color and circulation to ensure that the Thumb Sensor has not
restricted circulation.
The Thumb StrapWrap should securely hold the ViSi Mobile Thumb Sensor

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

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 Mobile 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).

Inspecting Equipment and Accessories
7.4 Inspecting Equipment and Accessories
After cleaning and disinfecting, you should visually inspect the ViSi Mobile Monitoring System
components and replace any System components that show evidence of anomalies.
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 (at flex points) for general
condition. Ensure there are no breaks or cracks in the cables . 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.
7.4.1 ViSi Mobile Chest Sensor
The Chest Sensor measures ECG/Respiration Rate (impedance pneumography) and skin surface
temperature. A standard patient simulator can be used to verify operation against the specifications found
in this Manual. The temperature sensor can be checked by submersing the sensor in a heated water bath
until the temperature sensor is submerged and comparing the ViSi displayed temperature against a
calibrated thermometer. Allow time for the ViSi temperature sensor to equilibrate with the water bath for
the time specified in the Temperature Specifications in this Manual.
7.4.2 ViSi Mobile SpO2 Sensor
The functionality of the SpO2 sensor can be verified using standard patient simulators. However, accuracy
should NOT be determined from patient simulators since they cannot duplicate human physiology. The
only way to determine accuracy is to compare the ViSi reading against a blood gas value. When
troubleshooting in a clinical setting, first inspect the sensor for proper placement as shown in this User
Manual.
7.4.3 ViSi Mobile Cuff Module
The functionality of the Cuff Module can be verified using a patient simulator capable of simulating
oscillometric blood pressure during the cuff inflation cycle. Consult your NIBP patient simulator manual
for information.
7.4.4 ViSi Mobile Charger
The charger initiates an internal calibration each time it is powered. In the case of an internal failure, the
indicator light will NOT turn green under any condition. If such a condition occurs return the Charger to
Sotera for service.

8. Patient Monitoring
8.1 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.
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 variable
heart rates. If frequent arrhythmias are suspected, their presence should be
confirmed by visual observation of the ECG waveform or another method,
such as a 12-lead ECG.
The ViSi Mobile Monitor does not provide 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, 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.
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.
To prevent settings from being inadvertently changed, lock the ViSi Mobile
Monitor screen (if enabled) as soon as tasks are completed.
113
Securing the Monitor

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 (manual or continuous) and skin temperature measurements do not have a
waveform.
To view the ECG waveforms
Depending on which Chest Sensor is connected (3 lead-wire or 5 lead-wire), several views (leads) of the
ECG waveform may be available for view.

Setting Up/Taking NIBP Measurements
8.4 Setting Up/Taking NIBP Measurements
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 measurements may not be reliable in the presence of atrial fibrillation or ventricular
arrhythmias.
Improper cuff size or application may lead to inaccurate readings.
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 NIBP 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.
Avoid touching the ViSi Mobile Disposable Cuff during cuff inflation as it may
disrupt the measurement.
Note: The ViSi Mobile Cuff Module cannot be used with the auscultatory method of measuring
NIBP.

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 occur, confirm the correct application of the ViSi Mobile Disposable
Cuff (see page 75) and then retake the measurementIf the measurement is still suspect, check
NIBP by another method and have maintenance performed as described in the Technical
Reference Manual.
Note: If viewing a waveform, the Start NIBP button will be hidden.
The performance of the automated sphygmomanometer may be affected by
extremes of temperature, humidity and altitude.

Setting Up/Taking NIBP Measurements
8.4.4 Calibrating Continuous NIBP Monitoring
Sotera’s continuous blood pressure monitor (cNIBP) is based on the relationship between blood pressure
and the time it takes a pulse that originates from a cardiac contraction to arrive at a peripheral location.
Pulse Arrival Time (PAT) is measured from the time an ECG R-Wave is detected to its arrival at the SpO2
thumb sensor. The shorter the time, the higher the blood pressure. Calibration of PAT for an individual
patient requires an initial NIBP cuff measurement. Once this measurement is made, continuous blood
pressure is displayed based on averaging PAT calculations from the previous 60 seconds and updating the
display every three seconds.
Calibrate whenever any of the following conditions occur:
•
•
A new patient starting cNIBP monitoring for the first time.
A monitor has been swapped.
Note: Recalibrate whenever an alert message requesting cNIBP calibration appears on the Monitor and
Remote Viewer. The message appears when any of the conditions stated in section To recalibrate
cNIBP on page 131 occur. .Continuous NIBP monitoring is an optional feature that requires
The accuracy of cNIBP is dependent on the initial cuff calibration. Use good
clinical practice to confirm cNIBP accuracy before initiating or treating a
patient.
The accuracy of the cNIBP measurement cannot be relied upon in patients
with a BMI greater than 35.
The ViSi Mobile Monitoring System accuracy claim (mean error of ≤ ±5
mmHg and a std. dev. of ≤ 8 mmHg) is not met when the subject is in a
semi-Fowlers position (inclined more than 30 degrees from horizontal).
Due to cNIBP signal averaging, there is a time delay of up to 120 seconds
between the instantaneous blood pressure reading and the displayed
reading.

9.8.1 Connectivity Lost
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.
9.8.2 Alarms and Alerts
When testing the speaker at the ViSi Mobile Remote Viewer, you are testing
how the alarm and alert tones will sound at the Remote Viewer during
typical operation. If the volume is inadequate, clinicians could miss alarms
and alerts. During testing, if the tone does not sound or it is not loud enough,
adjust the speaker volume.If the sound is still not loud enough, immediately
contact a biomedical engineer.
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 display at the ViSi Mobile
Monitor until the alert is acknowledged 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.
The vital sign alarm must be acknowledged, even if
the sensor is removed.
157
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 Mobile Remote Viewer, but there is no
audio on the ViSi Mobile Monitor.
Most alarms and alerts will audibly annunciate at the
ViSi Mobile 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?
158
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 your
biomedical engineer.
The speaker volume for the ViSi Mobile Remote
Viewer can be tested at any time.
The ViSi Mobile Monitor is not currently connected
to the network.
ViSi Mobile Remote Viewer
9.9 ViSi Mobile Remote Viewer
9.9.1 Setting Alarm Limits
Problem
Explanation
When I try to adjust individual limits in the Alarm
Settings pane, I cannot go past certain limit values.
Patient alarm limits may not be set beyond the care
unit alarm limits.
When I adjust an upper limit, the lower limit also
changes, or vice versa.
When a vital sign limit is adjusted 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 Mobile Remote Viewer until the Monitor
reconnects to the network.
The alarms were changed on the ViSi Mobile 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.

Continuous Non-Invasive Blood Pressure (cNIBP)
Normative Reference
ISO 81060-2: Non-invasive Sphygmomanometers - Part 2: Clinical validation of
automated measurement type.
Principle of Operation
cNIBP is based on the relationship between blood pressure and the time it takes a pulse
that originates from a cardiac contraction to arrive at a peripheral location.
Display Update
Continuous blood pressure is displayed based on averaging PAT calculations from the
previous 60 seconds and updating the display every 3 seconds.

Wireless Network Risk Mitigation
10.7 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 Mobile
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 interfere 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.If you have any
concerns regarding a cyber security breach or vulnerability, contact Sotera Wireless,
Inc. or an authorized Sotera Wireless, Inc. representative in your area.
Perform a risk assessment and verification before implementing a change or
modification to the IT infrastructure. Changes to IT network configurations can
compromise continuous vital signs monitoring and alarm delivery. on page 18
10.7.1 Risk Analysis Summary
•
•
•
The ViSi Mobile Monitors are the source of all alarms and alerts.
The ViSi Mobile Remote Viewer provides a supplemental alarm notification. When connectivity
is present audio alarms are deferred to the ViSi Mobile 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 Mobile Remote Viewer.
10.7.2 Residual Risks
Loss of network connectivity will result in failure in supplemental alarm notification to the ViSi Appliance
and ViSi Mobile 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.
Hand over protocol with all settings/configurations as installed and configured (Training)
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.
Maintain network configuration post installation of the ViSi Mobile System.
