LIFEPAK 15 Monitor/Defibrillator Operating Instructions
Monitoring ETCO2
EtCO
2
values are erratic FilterLine connection to device
is loose • Twist FilterLine connector
clockwise until tight and
firmly seated.
A leak in the FilterLine set • Check for connection leaks
and line leaks to patient,
and correct, if necessary.
A mechanically ventilated
patient breathes spontaneously
or patient is talking • No action required.
EtCO
2
values are consistently
higher than expected
Physiological cause such as
COPD • None.
Inadequate ventilation • Check ventilator, increase
ventilatory rate/bagging.
Patient splinting during
breathing • Supporting measures such
as pain relief.
Improper calibration • Contact qualified service
personnel.
EtCO
2
values are consistently
lower than expected
FilterLine connection to device
is loose • Twist FilterLine connector
clockwise until tight and
firmly seated.
Physiological cause • See Physiological factors in
"CO2 Detection" on
page 4-50.
Hyperventilation • Check ventilator, decrease
ventilatory rate/bagging.
Improper calibration • Contact qualified service
personnel.
CO
2
waveform stays elevated
for several seconds
Expiration is prolonged due to
bagging technique • Release bag reservoir
completely with expiration.
Observe that elevated
baseline returns to normal
level.
Sudden extreme increase in
EtCO
2
Fluid has entered CO
2
module • Contact qualified service
personnel.
XXX appears instead of EtCO
2
value
CO
2
module malfunction • Turn device off and then on
again.
• If problem persists, contact
qualified service personnel.
There is no EtCO
2
value and the
CO
2
waveform is flat
Measured CO
2
is less than
3.5 mmHg
• See "CO2 Detection" on
page 4-50.
