Set the A/D value of the inspiratory valve to cause the flow of inspiratory valve to reach a certain
value. In this case, the flows measured by the ventilator flow sensor, inspiratory flow sensor, and
expiratory flow sensor should be the same. Test multiple points by setting the A/D value of the
inspiratory valve. For each point, the flows measured by the three sensors should be the same. If not,
the measured value by the flow sensor is inaccurate. Troubleshoot the possible causes marked “*” in
the above table.
