LIFEPAK 15 Monitor/Defibrillator Operating Instructions
IP Monitoring Procedure
Prepare a flush system according to local protocols. Position the transducer at the patient’s
phlebostatic axis (zero-reference level).
To avoid offset errors, a zero reference must be established before any meaningful pressure
readings are obtained. This is done by opening the transducer stopcock to air so that
atmospheric pressure becomes the reference.
The P1 or P2 connector and Channel 2 or 3 can be used for IP monitoring. P1 and Channel 2 are
used in these instructions.
To monitor IP:
1. Prepare the transducer system according to the operating instructions provided with the
transducer and your local protocol.
2. Press
ON
.
3. Connect the IP cable to the transducer and to the P1 port on the monitor.
4. Use the default label
P1
or select
ART
,
PA
,
CVP
,
ICP
, or
LAP
. To change the label, select the
P1 area. From the menu, select
P1
. Select a label from the list.
5. Use the
SPEED DIAL
to outline and select
CHANNEL 2
on the Home Screen. From the
Channel 2 menu, select
WAVEFORM
and then select the label that is desired for the
waveform.
6. Open the transducer’s stopcock to air to zero the transducer and remove stopcock cap.
Select the
P1
area. Select
ZERO
from the menu. The message
P1 ZEROED
appears when
zeroing is complete and the pressure values are displayed as zeros.
7. Close the stopcock to air. The patient’s pressure waveform should be displayed. A scale is
automatically selected to display the pressure. Confirm that pressure amplitude correlates
with the digital readout.
Note: If you place a cap on an open port before you close the port to air, an error message
may appear. You will be required to zero the transducer again.
If pressure alarms are desired, set the alarms after you obtain a satisfactory waveform. Error or
alarm messages appear in the message area at the bottom of the screen. For more information,
see Alarms (on page 39).
