The user purchases a nose clip, detachable mouthpiece and disposable pulmonary
function meter filter, which must be a legally marketed product registered by the
FDA.
2) Clamp the nose clip, connect the mouthpiece, and breathe calmly for 4-5 times. After
the breathing is stable, inhale as much as possible at the end of the expiration at a
moderate speed (total lung volume), and then exhale to the end.
3) Repeat the above steps to check more than 3-5 times, and rest for more than 1 minute
between the 2 times.
4) Each time the tested patient completes a set of measured values, the monitoring page
will prompt whether the measured result is acceptable. Such as ticking is acceptable,
you can click "F3 Stop" to end this test and save the data. Such as the cross is an
unacceptable result and the reason is prompted, you can click " F1 start" to start a test.
5) The system will automatically obtain an acceptable quality level after the completion
of 3 blows. If there is a low- quality measurement record that is unacceptable for a
single operation, you can click to select the measured record to delete it.
