Apnea alarm delay AwRR: 10 to 40 s
* Conditions for measurements in typical precision:
The measurement is started after the preheating mode of the module;
Ambient pressure: 750 mmHg to 760 mmHg; room temperature: 22℃ to 28℃;
The gas under test is dry, and the balance gas is N2;
The deflation rate is 100 ml/min, the respiration rate is no greater than 50 BrPM, with a
fluctuation less than ±3 BrPM, and the inhale interval/exhale interval is 1:2;
When the working temperature is from 15 to 25 degree, or from 50 to 55 degree, or when the
breath rate is greater than 50Brpm, the measurement precision should meet the requirements of
ISO21647: ±4mmHg (0 to 40mmHg) or ±12% of the reading (41 to 99 mmHg)
