• After the flow sensor calibration is complete, there
can occur a transitional
Apnea
alarm. This alarm will
disappear after 5 seconds.
• If you close the
Tests & calib
window when the
calibration has failed, the device starts ventilating but
continues to display
Flow Sensor Cal. needed.
This can result in inaccurate monitoring.
• During flow sensor calibration, the device can recog-
nize a mismatch between the active patient profile
and the flow sensor type you are using. If this hap-
pens, the
Wrong Flow Sensor
type alarm will be
activated.
• The flow sensor must be in the correct position. If
you intend to ventilate with nCPAP-PS, the flow sen-
sor calibration has to be done with the flow sensor
at the proximal side of the patient and not at the
expiration valve of the ventilator.
Description: This calibration checks and resets the calibration
points specific to the flow sensor you are using.
Procedure for pediatric/adult flow sensor:
1. Set the ventilator for normal ventilation including a breath-
ing circuit, flow sensor, and expiratory membrane and
cover. Confirm you have, a) selected the correct patient
profile, and b) installed the appropriate flow sensor type
(pediatric/adult).
2. From the
Tests & calib
window, touch
Flow Sensor
to activate.
3. The message bar now displays
Disconnect patient
.
Disconnect the breathing circuit at the patient side of the
flow sensor. DO NOT block the open end of the flow sensor.
4. When the message bar displays
Turn the Flow sensor
,
reverse the ends of the flow sensor so the tubes are closest
to the Y-piece.
5. When the message bar again displays
Turn the Flow
sensor
, reverse the ends of the flow sensor so the tubes
are now away from the Y-piece.
