17 - 2
• Disconnect the sampling line from the module when CO
2
monitoring is not required.
• When sample gas of 37 °C, sample flowrate of 50 ml/min, room temperature of 23 °C, 100% RH, the
sampling line with a general type should be replaced once at most every 8 hours, and the sampling
line with a humidified type should be replaced once at most every 72 hours.
17.2.2 Zeroing the CO
2
Sensor
• The CO
2
module temporally stops measuring during zeroing.
17.2.3 Selecting Gas Compensations
• Make sure that the appropriate compensations are used. Inappropriate compensations may cause
inaccurate measurement values and result in misdiagnosis.
17.3 Removing the Exhaust Gases from the System
• When taking the CO
2
measurement on patients who are receiving or have recently received
anesthetics, connect the outlet to a scavenging system, or to the anesthesia machine/ventilator, to
avoid exposing medical staff to anesthetics.
17.4 CO
2
Calibration
• Connect the gas outlet to the scavenging system when calibrating CO
