Chapter 7: Alarms and messages

GENERAL INFORMATION

The device must be operated so that the alarm is audible and visible by the 
user. Audible alarms can be forwarded using the nurse call or the alarm box.

The CARAT II pro ventilator is equipped with fixed and adjustable alarms, relating 

to the respective ventilation modes. 
There are 3 alarm priorities:

Alarm priority

  What action is required?

HIGH

Immediate action is required. Monitor the patient and the cause of 
the alarm closely.

MEDIUM

Fast action is required for medium priority alarms. Correct the cause 
of the alarm.

LOW

User attention is requested for low-priority alarms. Low-priority 
alarms indicate a change at "normal" device operation. Check the 
cause of the alarm.

 

Alarms will lowered in the priority when the alarm event is no longer fulfilled.
The alarm will stay in active until it has been confirmed with the alarm key.

ALARM SOUND TEST

A hardware test is performed with each device start-up. The primary and sec-
ondary alarm sound transmitters are tested (see page 42). Both alarm sound 
transmitters must emit a short beep in sequence. Otherwise, an error message is 
issued and the device must be returned for servicing.
