CO2 module will automatically zero when necessary and the sampling tube is not
be inserted.
15.9. Calibration
The monitor has already been calibrated before leaving factory. User can directly
apply it measuring in normal conditions (except for the following three cases). Calibrate
the gain of the sidestream CO2 module when the following three conditions occur.
After the CO2 module is used for half a year and one year;
Clinicians doubt the accuracy of readings;
After the latest calibration, atmospheric pressure or height above sea level
varies evidently.
CAUTION:
Recommend that users carry out calibration operations under the guidance of
technical service personnel authorized by the manufacturer. Incorrect
calibration procedures may lead to incorrect readings.
Masimo IRMA CO2 and Nomoline ISA CO2 have been permanently calibrated
at the factory and do not need to be calibrated by the user.
15.10. Exhaust Emission
WARNING:
When using the sidestream/microflow CO2 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.
Use an exhaust tube to remove the sample gas to a scavenging system. Attach it to the
outlet connector of LoFlo CO2 sensor.
