LIFEPAK 15 Monitor/Defibrillator Operating Instructions
Inspiratory Downstroke
The fall to baseline (IV-V segment) is a nearly vertical drop. This
slope can be prolonged and can blend with the expiratory plateau in cases of leakage in the
exhale portion of the breathing circuit. The peak EtCO
2
value (IV) is often not reached. Relying
on the numeric end-tidal value without observing the breathing waveform may obscure the
presence of a leak.
EtCO2 Monitoring Procedure
When activated, the EtCO
2
monitor draws power from the defibrillator. The
LIFEPAK 15 monitor/defibrillator activates the EtCO
2
monitor when it senses the attachment of
the FilterLine set. Initialization, self-test, and warm up of the EtCO
2
monitor is typically less
than 30 seconds, but may take up to two-and-one-half minutes.
Possible Equipment Damage
Failure to replace a broken or missing CO
2
port door
may allow water or particulate contamination of the
internal CO
2
sensor. This may cause the CO
2
module to
malfunction.
To monitor EtCO
2
:
1. Press
ON
.
2. Select the appropriate EtCO
2
accessory for the patient.
3. Open the CO
2
port door and insert the FilterLine connector; turn connector clockwise until
tight.
4. Verify that the CO
2
area is displayed. The EtCO
2
monitor performs the autozero routine as part
of the initialization self-test.
Note: If you use a ventilation system, do not connect the FilterLine set to the
patient/ventilation system until the EtCO
2
monitor has completed its self-test and warm-up.
5. Display CO
2
waveform in Channel 2 or 3.
6. Connect the CO
2
FilterLine set to the patient.
7. Confirm that the EtCO
2
value and waveform are displayed. The monitor automatically selects
the scale for the best visualization of the waveform. You can change the scale, if desired, as
described in the next section.
Note: It is possible for the FilterLine set to become loose at the device connection and still have
an EtCO
2
value and CO
2
waveform, but they may be erroneously low. Make sure the FilterLine
connection is firmly seated and tight.
Note: The capnography module performs self-maintenance within the first hour of monitoring
and once an hour during continuous monitoring. The self-maintenance includes "auto-zeroing."
Self-maintenance is also initiated when the surrounding temperature changes 8°C (14.4°F) or
more, or the surrounding pressure changes greater than 20 mmHg. The CO
2
module detects this
change and attempts to purge the tubing. To clear the
CO2 FILTERLINE PURGING
or
CO2 FILTERLINE BLOCKAGE
messages, remove the FilterLine tubing and reconnect it to the
monitor.
