5.4.7 High intrinsic
PEEP
troubleshooting
Start
Zero Flow and
airway pressure
transducers
Verify pass?
No
Pressure Transducer Problem
1. Perform airway pressure
transducer calibration
2. Check pneumatic lines
Yes
Flow from bleed
orifice with BTV
switch in bag
position?
Problem
continues?
Transducer was
out of calibration
Scavenging Problem
or Breathing Circuit Obstruction
1. Check hospital’s scavenging
hoses and supply vacuum (active)
2. Check filter on active systems
3. Check for obstruction in breathing
circuit down tube or Y manifold
4. Check breathing circuit for
incorrect assy or obstructions
Instrinsic PEEP
in both Bag and
Vent Modes?
No
Yes
No
Yes
No
Intrinsic
PEEP
in Vent
Mode?
Exhalation/Pop-off Valve Problem
1. Check bellows pop-off valve for
accurate assy or sticking
2. Check exhalation valve for accurate
assy or sticking diaphragm
3. Check for obstructions in bellows
base upstream of exhalation valve
4. Check for obstruction downstream
of exhalation valve in connecting
tube or Y manifold
Yes
APL Valve Problem
1. Check APL Valve mechanism
for proper function
2. Check APL disk for sticking
3. Check for obstructions in
main manifold downstream
of APL or in Y manifold
Verify
Regulator
calibration
Yes
No
Problem
continues?
No
Regulator was out
of calibration
PEEP Control Valve Problem
1. Verify Calibration
2. Replace PEEP Control Valve if necessary.
3. Inspect Vent Engine and manifold for
evidence of debris or water
4. Verify proper operation of PEEP safety
valve
Yes
