Gas Measurement Failure; Flow Measurement Failure - Dräger Perseus A500 Instructions For Use Manual

Gas measurement failure

CAUTION
Risk due to gas measurement failure
If the gas measurement fails, the patient can no
longer be adequately monitored.
– Ensure corresponding substitute monitoring.
– Check sample line and water trap for damage
or blockage and resolve these as needed.
Observe the exchange intervals.

Flow measurement failure

If the flow measurement fails, normally the therapy
can be continued. Thus, the flow sensors can be
exchanged during the next Standby. There may
be limitations in measured parameters or selection
of therapy.
WARNING
Risk due to malfunction of the inspiratory
flow measurement
If the inspiratory flow sensor malfunctions,
the device automatically switches to
pressure-controlled ventilation. If there is an
additional malfunction of the inspiratory
pressure sensor, the system automatically
switches to the non-synchronized PC - CMV
mode.
In either case, check the ventilation settings
and adjust as needed.
1 Replace the flow sensor:
To remove the flow sensors, follow the steps
described in chapter "Inserting the flow sensors
and the ports" in reverse order, see page 65.
Then install the new flow sensors.
2 Perform the leakage test, see page 123.
