NFS Checkout Complete
Neonatal flow sensor flow check completed,
None
No Air
Supply pressure for Air is below 30 psi.
Verify proper gas supply.
No Exp Flow Sensor
Expiratory flow sensor is not detected by
system.
Verify proper installation of expiratory flow
sensor and exhalation housing. Replace
expiratory flow sensor if necessary.
No Gas Supply
Supply pressure for both Air and O2 is below 30
psi.
Verify proper gas supply.
No Oxygen
Supply pressure for O2 is below 30 psi.
Verify proper gas supply.
No Supply Pressure
Supply pressure for both Air and O
2
is below
30 psi.
Verify proper gas supply.
None
No calibrations, zero measurements, or
checkout tests are running
None
Normalized Flow
Comparison Failed:
>Target = Value1
>I = Value2
>E = Value3
Normalized expiratory flow and total flow are
more than 10% (or 200 mL, whichever is
greater) apart.
Value1 = Normalization Table flow point being
tested (mLpm)
Value2 = Inspiratory Flow measured by total
flow sensor (mLpm)
Value3 = Expiratory flow measured by expiratory
flow sensor (mLpm)
1. Verify breathing circuit is connected and not
leaking.
2. Verify low pressure vent engine is not leaking.
3. Verify exhalation valve is properly connected
and all seals are in place.
4. Verify gas flow from flow control valves. Recal
if necessary.
O2 Flush Time: Value
sec
Value
= time (sec) needed to flush system with
O
2
until stability of 0.1% O
2
is reached.
None
O2 Sensor Fail
Failed Paracube communications during O
2
sensor check
Replace Paracube.
O2 Sensor: Failed 100%
Cal
Paracube Cal never competed, timed out during
100% O
2
cal
Check paracube sensor.
O2 Sensor: Failed 21% Cal
Paracube Cal never competed, timed out during
21% O
2
cal
Check paracube sensor.
O2 Too Low for 100% Cal
Measured O
2
% < 41% during the 100% span
calibration of the O2 sensor.
1. Verify proper connection of gases to
ventilator.
2. Use the Service App’s
O2 Sensor
cal to
override limits on O
2
sensor calibration.
3. Replace Paracube.
