Monitoring
3-20 LIFEPAK 20e Defibrillator/Monitor Operating Instructions
CO2 Display
The following scales are available to display the CO2 waveform. The LIFEPAK 20e
defibrillator/monitor automatically selects the scale based on the measured EtCO2 value. To
change the CO2 scale, outline and select the CO2 area using the Speed Dial
and then select the
desired scale from the scale menu.
• Autoscale (default)
• 0–20 mmHg (0–4 Vol% or kPa)
• 0–50 mmHg (0–7 Vol% or kPa)
• 0–100 mmHg (0–14 Vol% or kPa)
The CO2 waveform is compressed (displayed at 12.5 mm/sec sweep speed) to provide more
data in the 3.7-second screen. There is a slight delay between when the breath occurs and when
it appears on the screen. Printouts are at 25 mm/sec.
The monitor shows the maximum CO2 value over the last 20 seconds. If the EtCO2 values are
increasing, the change can be seen with every breath. However, if the values are continually
decreasing, it will take up to 20 seconds for a lower numerical value to be displayed. Because of
this, the EtCO2 value may not always match the level of the CO2 waveform.
CO2 Alarms
The EtCO2 monitor provides:
• EtCO2 high and low alarms (controlled by activating Alarms (refer to "Setting Alarms,"
page 2-17)).
• FiCO2 (inspired CO2) alarm (controlled by activating Alarms; automatically set to default
values and not adjustable)
• Apnea alarm (automatic and not adjustable)
• Respiration Rate high and low alarms (controlled by activating Alarms (refer to "Setting
Alarms," page 2-17)).
Note: The apnea alarm occurs when a breath has not been detected for 30 seconds. The
message
ALARM APNEA appears in the message area along with the time since the last
detected breath.
