Diagnostic Codes
2125 Inhalation and exhalation pressure
transducer disagreement.
Patient circuit test (test 11): the
difference between the inhalation
and exhalation pressure transducers
is >3 cmH
2
O.
1. Check patient circuit for leaks.
2. Replace sensor PCB.
3. Replace analog PCB.
4. Replace main PCB.
2128 Circuit compliance out of range.
Patient circuit test (test 11): circuit
compliance is calculated by
measuring the time required to
achieve 50 cmH
2
O at 5 LPM. This
code indicates that calculated
compliance is < 0.50 ml/cmH
2
O or
>9.0 ml/cmH
2
O.
1. Remove inspiratory bacteria filter and
external oxygen sensor and try
another patient circuit.
2. Replace sensor PCB.
3. Replace analog PCB.
2129 Pressure leak out of range.
Patient circuit test (test 11): the
patient circuit leak rate (based on
calculated compliance value) is
determined by measuring the
decrease in circuit pressure from 50
cmH
2
O after one second. This code
indicates that the pressure leak was
out of range, based on the
calculated compliance value.
1. Remove inspiratory bacteria filter and
external oxygen sensor and try
another patient circuit.
2. Rerun leak test while blocking
exhalation flow sensor outlet. If leak
stops, replace exhalation valve.
3. Replace sensor PCB.
4. Replace analog PCB.
2130 Safety valve cannot open.
Safety valve test (test 2): the
exhalation valve is opened then
closed to vent circuit pressure. The
safety valve solenoid (SOL2) is then
deenergized to open the safety valve,
and a 10 LPM air flow starts while
monitoring the inspiratory pressure
transducer (PT3). This code
indicates that PT3 is measuring >5
cmH
2
O.
1. Check safety valve and safety valve
solenoid (Chapter 5).
2. Check for blocked vent tube between
the inspiratory manifold and the back
of the ventilator.
3. Replace three-station solenoid
assembly.
4. Install safety valve kit.
5. Replace inspiratory manifold
assembly.
6. Replace main PCB.
7. Replace CPU PCB.
2131 Patient wye not blocked.
Block patient wye (test 1): after the
prompt to block the wye, the safety
valve and exhalation valves close.
The ventilator starts a 5 LPM air
flow, and the inspiratory pressure
transducer (PT3) should measure
>10 cmH
2
O. This code indicates
that PT3 is measuring <10 cmH
2
O.
1. Check that patient wye is blocked
and circuit is tightly connected.
2. Ensure that exhalation filter door is
securely closed.
3. Replace exhalation filter and rerun
test.
