•
Set the Tidal Volume ( TV ) to 500 ml/min when doing calibration check and calibration with
adult sensor and 100 ml/min with pediatric sensor.
•
Set the RR =15, I/E =1/2 and PEEP 0cmH2O.
4.3.2 Calibration check
1. Perform the calibration check according to the steps 1 through 12a in the "Instructions for
Use" -letter of the spirometry tester.
NOTE: Let the gas module to warm up at least for 10 minutes before performing the calibration
check or flow calibration.
2.
The measured flow values are shown in real-time in the TV Insp and TV Exp fields in the
Flow parameter window. Compare these measured values to the TV value reading
(highest water level) in the spirometry tester.
Acceptance criteria:
•
If the TV Insp and TV Exp values differ less than ± 6% of the value read from the
spirometry tester, flow calibration is not needed.
•
If the TV Insp and TV Exp values differ more than ± 6% of the value read from the
spirometry tester, perform flow calibration according to section “4.3.3 Flow calibration”.
4.3.3 Flow calibration
1. Select Monitor Setup > Service Calibrations
2. Enter the User Name and the Password and press Enter to get into the Calibrations
menu.
3. Select Gases
4. Select Spirometry Calibration
5. Ensure that the Sensor Type is correct and that Spirometry Zeroing is Enabled.
6. Wait until the MiniPVX sensor performs an automatic zeroing. It will show a message
‘zeroing’ in the Flow parameter window when zeroing takes place.
7. Adjust the Exp Flow Gain and/or Insp Flow Gain separately by using the related up-down
spinner controls to calibrate the measured TV Exp ml and TV Insp ml values:
− To increase the TV Exp ml flow value, increase the Exp Flow Gain .
−
To decrease the TV Exp ml flow value, lower the Exp Flow Gain .
− To increase the TV Insp ml flow value, increase the TV Flow Gain .
−
To decrease the TV Insp ml flow value, lower the TV Flow Gain .
8. Press Confirm to check the effect of the gain adjustment to the flow readings.
9. Repeat steps 6 and 7 until the flow values are within the specification.
