Monitoring of the mattress pressure
The system will alarm if the pressure deviates from set value. If a compressor failure (or big leak)
prevents the set pressure from being reached then the fans and heating will not start.
If the electronic pressure control fails to stop the compressor then a mechanical over pressure valve will
prevent the pressure from exceeding 75mb. A sudden pressure drop (puncture or loose hose) will
create an alarm and stop the system.
Monitoring of the fans
The system uses two high quality silent fans that periodically changes the air direction in order to
achieve an even temperature distribution under the patient. In case one fan stops the system will alarm
and enter into “safe mode” (See Error code 009). Change of temperature must be done after careful
consideration of the fact that the air is constantly going in the same direction (“hot-spot” hazard).
Monitoring of the temperature regulation
The electronic temperature sensors (one in each hose connection at the Main Unit) will alarm if the air
temperature deviates from selected value. Mean air temperature and peak temperature values are
monitored. The system is also equipped with 2 capillary thermostats that will cut the heating if the
electronics should fail. As a third independent passive patient protection the mattress is equipped with
a temperature sensitive weak point that will puncture the mattress if the temperature should pass
critical values.
