13.5 Zeroing
 Mainstream CO
2
module and Microstream CO
2
module
Zeroing allows the CO
2
sensor to adjust to the optical characteristics, in
order to obtain accurate readings. While zeroing is recommended the first time
a CO
2
sensor is connected to the monitor, it is only absolutely necessary when
the message“Zero Required”is displayed.
Follow these steps:
1.
Ensure that the nasal cannula or airway adapter is not connected to the
patient or close to any source of CO
2
(including the patient's, your own,
exhaled breath and ventilator exhaust valves).
2.
Select【Zero】in the CO
2
parameter setting menu, this will start zeroing. The
monitor zeroes the sensor and displays the message “Zero In Progress” for
about 15-20s on the screen. The message disappears upon completion of the
zeroing.
Caution:
 Always ensure that the sampling tube is properly connected to the
microstream CO
2
sensor before zeroing.
 Always ensure that the mainstream CO
2
sensor is properly connected to
the airway adapter before zeroing.
 Do not attempt zeroing for 20s after removing the adapter or cannula
from the patient’s airway. This time allows any CO
2
remaining in the
adapter or cannula to dissipate before zeroing.
 Do not attempt to zero the sensor while the adapter or cannula is in the
patient’s airway.
 Do not attempt zeroing if the temperature is not stable.
 Zeroing with CO
2
in the adapter or cannula can lead to inaccurate
