Response time

When measured with a watertrap and a 2.5 m-long sampling line:

<5.5 s @ 100 ml/min

<7 s @ 70 ml/min

Delay time

When measured with a watertrap and a 2.5m-long sampling line:

<5 s @ 100 ml/min

<6.5 s @ 70 ml/min

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 be ±4mmHg (0 to

40mmHg) or ±12% of the reading (41 to 99 mmHg)
