LIFEPAK 15 Monitor/Defibrillator Operating Instructions
Monitoring ETCO2
Similar to the diminished slope of the Expiratory Upstroke, this pattern can occur in asthma,
chronic obstructive pulmonary disease (COPD), partial upper-airway obstruction, or partial
mechanical obstruction such as a partially kinked ETT.
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.
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.
CAUTION
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.
