Otherwise, when no air has moved for three seconds, the following happens:
•
For verifications or single-flow calibrations
The results display.
•
For multiple-flow calibrations
Another simulated exhalation screen appears. Repeat from
twice more.

10. Review your results.
Check the error percentages for the expired and inspired volumes. Both/all must be
less than ±3% for your calibration to be acceptable. For single-flow calibrations, the
measured and adjusted curves should match. See the following examples.
