19.0.13 Calibration Fail
For some reason the flow sensor will not calibrate, even if the message has been
“Calibration Complete”. The reason could be that the sensor is defective due to
mishandling, or has secretions preventing adequate flow through the sensor.
Action: Handle sensor according to the guidelines laid out in the user manual.
Replace with new sensor.
19.0.14 Calibrate Flow Sensor
This alarm is generated every time the ventilator is powered up, or if the flow
sensor and patient manifold have been disconnected in the incorrect sequence.
Action: Recalibrate the flow sensor. Take care when disconnecting the patient
manifold and sensor that it is done in the correct sequence.
19.0.15 Apnoea (volume)
This alarm is generated when the time between breaths exceeds the selected
apnoea delay time. This will happen in patient interactive modes of ventilation e.g
PSV, PTV, SIMV, CPAP.
Action: Check patient effort. The breath detection level may need to be adjusted
as perhaps all patient effort was not being captured. The same could apply when
the Apnoea alarm is triggered in pressure triggering mode i.e. no flow sensor in
situ.
