For the Masimo Sidestream CO
2
module:
The highly stable Masimo Sidestream CO
2
module requires no regular zeroing. A room air
reference measurement is performed when the NomoLine is disconnected from the gas inlet,
provided that CO
2
measurements are stable. This zeroing procedure is indicated by the blinking
green.
For the Respironics Mainstream CO
2
Module:
1.
Wait until the monitor’s warm-up message disappears; correctly install the mainstream CO
2
sensor to airway adaptor and remove it from breathing circuit, keep the monitor away from
CO
2
source.
