* Accuracy applies for the following conditions:
1. Measurements begin after the CO
2
module warms up;
2. Ambient pressure is from 750 to 760 mmHg, and ambient temperature from 22 to 28ºC;
3. The measured gas is a dry gas and the balance gas N
2
;
4. Gas sample flow rate is 150ml/min, respiration rate is 30 rpm with a fluctuation between
±3 rpm, and I:E is 1:2.
For other conditions, the accuracy complies with EN864 or ISO9918: ±4mmHg (0 to
40mmHg) or 12% of the reading (41 to 99mmHg).
