mode of testing and the display will

breathing hard to commence the
test.

The patient should be instructed to
tidal breath. The tidal breaths are
automatically detected prior to
commencing the MVV maneuver.
Once tidal breathing is complete,
the display will change and an
audible beep heard to instruct the
patient to start rapid, fast
breathing. The start button should
be touched using the stylus to start
registering the MVV maneuver.
