C. Warnings and Precautions
The SonarMed AirWave Monitoring System (Monitor and Sensor) is not to be used as a diagnostic
tool; it is to be used as an adjunct to airway management only.
The SonarMed AirWave is to be used by properly trained personnel only.
Do not use an AirWave Sensor if its pouch is open or damaged.
Do not use the AirWave Monitor if it is damaged.
The AirWave Monitor is rated IPX1 for water ingress protection, which means the Monitor is resistant
to water dripping vertically onto the device. Other types of water exposure (e.g. sprays, submersion)
should be avoided.
Only the SonarMed AC-DC power supply may be used with the SonarMed Monitor. Use of another
power supply may put the patient at risk of an electrical hazard. Warning: To avoid the risk of electric
shock, this equipment must only be connected to a supply mains with protective earth.
When the Alarm Silence button is pressed, the Monitor speaker is disabled for two (2) minutes even if
a new alarm should occur during that period.
Some AirWave alarms may be manually disabled by the user. The Monitor will display the message
“An Alarm is Off” when this is the case. All alarms that have been disabled are reactivated to their
previous settings if the Monitor is powered off and back on.
Only upgrade firmware when the AirWave system is off the patient.
Presence of high oxygen levels (O
2
> 40%) or anesthesia gases affects the speed of sound. For best
results, it is important to modify the settings as described in Section G.c.
When using the SonarMed AirWave device in conjunction with a high frequency oscillatory ventilator
(HFOV), the manufacturer’s safety information and recommendations should be followed.
Only connect an ETT to an AirWave Sensor nozzle specified for that ETT ID. Failure to do so may
result in an unsecure fit between the Sensor and ETT and/or may cause the AirWave to provide
erroneous results.
The AirWave Sensor cable must be routed and secured in a way that prevents accidental disturbance
by the user, patient, or other persons.
If attaching the AirWave Sensor to an already intubated patient, care must be taken not to dislodge
the ETT while removing the standard ETT adapter and attaching the AirWave Sensor.
While using the AirWave’s feature for directly listening to the signals from the Sensor microphones,
system monitoring of ETT is discontinued until the system is returned to the patient monitoring
screen. This feature is used to both troubleshoot and listen to the patient’s breath sounds.
Improper cleaning methods or materials may damage the AirWave Monitor.
This device is a precision electronic instrument and must be repaired by qualified technical
professionals. Field repair of the device is not possible. Do not attempt to open the case or repair the
electronics. Opening the case may damage the device and voids the warranty.
