4.4.6 Breathing
System Leak Test
You can estimate how much of a leak there is in the ventilator portion
of the breathing system by closing the patient circuit, inflating the
bellows, and observing how quickly they fall on their own weight (part
of machine checkout procedure).
The Breathing System Leak Test allows you to more precisely test
the ventilator portion of the breathing system for leaks.
Note The Inspiratory Flow Valve Calibration and PEEP Valve
Calibration should be performed before you do the Breathing
System Leak Test.
Note The regarding plug is located on the breathing system bag port.
Remarks By using the patient circuit to establish a closed loop, you can
measure the leak rate.
• The leak rate is the fresh gas flow needed to maintain 30 cm
H

O.
• The system should have a leak rate < 200 mL/min.
