8.5 Zeroing
Zeroing allows the CO
2
module to adjust to the optical characteristics, in order to
obtain accurate readings. While zeroing is recommended the first time a CO
2
module
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 module 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
module 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 module while the adapter or cannula is in the
patient’s airway.
