The subject should then inhale to TLC (Total Lung Capac
ity), lungs
full, then perform a ‘Valsalva’ manoeuvre, a forced exhalation
against the MicroRPM with as much effort as possible for as long as
possible (minimum 2 seconds).
The display will report the result, the maximum average expiratory
pressure sustained over a 1 second period of the test, in cmH2O.
Ideally, the subject should repeat this test 3 times to ascertain a
best value.
To repeat either the PImax or PEmax tests the MicroRPM must firstly
be returned to the ‘Off’ position.
