S12 Vet Monitor User’s Manual

CAUTION:
Before zeroing, the BLT sidestream/ microflow CO
2
sensor must be connected
with the sampling tube.
Before zeroing, the mainstream CO
2
sensor must be connected with the airway
adapter.
Zeroing should not be performed for 20 seconds after the airway adapter or
cannula is separated from the patient's airway. Wait a moment before zero
correction to dissipate the remaining CO2 in the adapter or cannula.
Zeroing should not be performed when the airway adapter or cannula is
connected to the patient's trachea.
When the temperature is not stable, please do not adjust to zero.
When CO
2
remains in the airway adapter or casing, zeroing will result in
inaccurate measurement or other error conditions. The time required for zeroing
will also increase.
When zeroing, do not rely on gas readings.
Nomoline ISA CO
2
module does not require user to manually zeroing, and the
user cannot successfully send the zeroing command to the module. When
necessary, the sampling tube should be pulled out for automatic zero.

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). When the
following three conditions occur, please return the CO
2
module to the factory for
calibration.
After the CO
2
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.
