Accuracy
a
a. Accuracy applies for respiration rate up to 80 b/min. For respiration rate above 80 b/min, the
accuracy complies with EN 864/ISO 9918 (4 mmHg or ±12% of indicated value, whichever
is greater) for End-tidal CO

values exceeding 19 mmHg. The above accuracy is maintained
to within 4% for the following gas mixtures: CO
