LIFEPAK 15 Monitor/Defibrillator Operating Instructions
Monitoring Invasive Pressure
Cleaning
IP transducers are disposable and are intended for single-patient use. Do not clean and reuse
transducers. Dispose of the contaminated waste according to local protocols.
IP cables are reusable and may be cleaned. To clean the reusable IP cable:
1. Disconnect the cable from the monitor.
2. Use a clean, soft cloth dampened with a germicidal solution to wipe clean.
3. Allow to dry before reconnecting the cable to the monitor.
For information about cleaning the device, see "Cleaning the Device" on page 10-15.
Troubleshooting Tips
The error messages in Table 4-8 use the text
PX
to represent any of the labels for invasive pressure,
including P1, P2, and the user-selectable labels ART, PA, CVP, ICP, and LAP.

OBSERVATION
POSSIBLE CAUSE
CORRECTIVE ACTION
Invasive pressure value is blank
No transducer is connected
• Connect the transducer to the
cable, and the cable to the
monitor.
No scale appears next to the
waveform
The zero reference has not
been established
• Zero the transducer.
PX NOT ZEROED
message appears
The zero reference has not
been established
• Zero the transducer.
PX ZERO FAILED
message appears
An unsuccessful attempt
has been made to set a zero
reference value
• Make sure that the transducer
is open to air and repeat the
attempt to zero.
Dampened waveform
Loose connection
• Check the entire system for
leaks. Tighten all connections.
Replace any defective
stopcocks.
Tubing too long or too
compliant
• Use short, stiff tubing with
large diameter.
Thrombus formation, air
bubbles, or blood left in
catheter after blood draw
• Use syringe to draw back air or
particles in catheter, and then
flush system.
Kinked catheter, catheter
tip against vessel wall,
arterial spasm
• Reposition catheter. Anchor
catheter to skin at insertion
site.
Resonating waveform
Tubing too long
• Use short, stiff tubing with a
large diameter.
