Visually check for leaks, cracks and open ports on the circuit
•
Check cap/diaphragms
•
Check the water trap stopcock (may be open or missing)
•
Ensure the circuit set up is correctly
•
Confirm the bias flow is set exactly at 20 LPM (the middle of the ball is at the

•
Check the airway pressure luer fittings for cracks
•
Check the calibration screw (clicking indicates a defective valve)
•
Confirm the pressure transducer zero: With the circuit stopper in place, but the
system not pressurized, the Paw should read 0 cmH
