Ventilator Alarms
This section describes all of the ventilator alarms and informational messages in order of priority, from high priority alarms to low priority alarms and finally informational messages. Refer to Chapter 6 for more information on alarms.
Loss of Power Alarm
This is a high priority alarm. It may occur when a complete power failure has occurred and power was lost while the device was providing therapy. This may happen if the internal battery was the only power source in use and was completely depleted.
Ventilator Inoperative Alarm
This is a high priority alarm. It occurs when the ventilator detects an internal error or a condition that may affect therapy. The device will shut down if the cause of the failure indicates that the device cannot deliver therapy safely. If the device can deliver therapy at a limited level, the device will continue to deliver limited therapy.
Ventilator Service Required Alarm
This is a high priority alarm. It occurs when the device cannot perform to specification, a backup safety feature is compromised, or the delivery of therapy is compromised. The device continues to operate (possibly in a reduced capacity mode). If the problem is not corrected, the device will generate a reminder message once per hour until the issue is corrected. Additionally, if therapy is stopped, a reminder message will immediately appear when therapy is turned on again.
