Patient Circuit
(Test 11, Step 1)
A-20
This step pressurizes the circuit with air to measure tubing compliance and
leak rate, and includes several time-dependent sub-tests.
Diagnostic code 3106 indicates a leak in the circuit that prevents the circuit
from being pressurized. Diagnostic code 3107 occurs if a leak rate is
excessive. Diagnostic code 3125 occurs if PT2 and PT3 disagree by >3
cmH O. Diagnostic code 3128 occurs if calculated compliance is <0.5 or
2
>9.0 mL/cmH O. Diagnostic code 3129 indicates a leak in the circuit that is
2
out of range.
