* Conditions for measurements in typical precision:
The measurement is started after the preheating mode of the module;
Ambient pressure: 750mmHg to 760mmHg; room temperature: 22 to 28 ;
℃
℃
The gas under test is dry, and the balance gas is N2;
The deflation rate is 150ml/min, the respiration rate is no greater than 30BrPM, with a
fluctuation less than ±3BrPM, and the inhale interval/exhale interval is 1:2;
In other conditions, the measurement precision should meet the requirements of EN864 or
ISO9918: ±4mmHg (0 to 40mmHg) or ±12% of the reading (41 to 99mmHg)

* Precision applies for breath rates of up to 80 bpm. For breath rates above 80 bpm, accuracy
complies with EN 864/ISO 9918 (4 mmHg or ±12% of reading whichever is greater) for EtCO

values exceeding 18 mmHg. To achieve the specified accuracies for breath rates above 60
breaths/minute, the Microstream® FilterLine H Set for Infant/Neonatal (p/n 006324) must be
used.
The accuracy specification is maintained to within 4% of the values indicated in the above table
in the presence of interfering gases according to EN864 Section Eleven, Part 101.
