Fig. 5-6 On-screen message warning of a leak less than 10
L/min during calibration.
NOTE
• While it is possible to start to ventilation with a
leak detected during the calibration, less than
10 L/min, it is recommended not to ventilate a
patient when leak is detected by the circuit.
If the leak detected is greater than 10 L/min, the circuit calibration is aborted. Until
the leak is repaired, the equipment will fail the calibration stage, and will not start
operating (Fig. 5-7).

On-screen message showing a leak greater than
10 L/min during calibration.
WARNING
• In the event of a significant leak, check the
patient circuit to detect the section with the
leak. Replace or repair the segment to pre -
vent any improper change in ventilation.
If while performing the calibration circuit, the airtightness of the patient circuit is
lost, or the valve is defective, the calibration shall not be completed, and the screen
will display the message in Fig. 5-8.
