Monitoring ETCO2

LIFEPAK 15 Monitor/Defibrillator Operating Instructions
When CO
2
is not detected in the cardiac arrest situation—for example, the CO
2
waveform is
either dashes "---" or a flat solid line at or near zero—several factors must be quickly evaluated.
Assess for the following causes:
Equipment issues
•
Disconnection of the FilterLine set from the endotracheal tube (ETT)
•
System is purging due to fluid in the patient/sensor connection from ET administration of
medications
•
System is auto-zeroing
•
Shock was delivered and system is resetting
•
Loose FilterLine set to device connection
Loss of airway function
•
Improper placement of ETT
•
ETT dislodgment
•
ETT obstruction
Physiological factors
•
Apnea
•
Loss of perfusion
•
Exsanguination
•
Massive pulmonary embolism
•
Inadequate CPR
Cleaning
Accessories for CO
2
monitoring are disposable and are intended for single-patient use. Do not
clean and reuse a FilterLine set. Dispose of the contaminated waste according to local
protocols.
For information about cleaning the device, see Cleaning the Device (on page 212).
