etCO2 Alarms
The monitor alarms for the following etCO
2
parameters:
! etCO
2
alarm (critical levels of CO
2
saturation in the exhaled
breath).
! iCO
2
alarm (critical levels of CO
2
saturation in the inhaled
breath, or rebreathing).
! RRc alarm (significant changes in the respiratory rate,
derived from the capnogram waveform).
! RRc Apnea alarm (apnea conditions based on the respiratory
rate derived from the capnogram waveform).
In addition, the monitor alarms for unplugged cables, weak sig-
nals, and in the absence of periodic measurement updates.
You can set etCO
2
upper and lower limits for all monitoring
modes within the following range:
! 5 to 95 mmHg for the etCO
2
alarm (0.7 to 12.7 kPa or %).
! 4 to 10 mmHg for the iCO
2
alarm (0.5 to 1.3 kPa or %).
! 5 to 145 breaths per minute for the RRc alarm (mainstream).
! 5 to 65 breaths per minute for the RRc alarm (sidestream).
Turn etCO
2
alarms on or off and set the alarm limits in the Alarm
Limits table (see the chapter Alarms and Messages).
