Note: Patient efforts is acceptable
when:

Indicated to the user by the breath
rate being displayed in green (>65
breaths per minute).
Lasted a full 12 seconds manoeuvre.
Indicated to the user by a green line
being displayed – the patient should
ideally continue until the test is
automatically terminated at 15s.
Interruption i.e. Did not cough.
Once the test has finished the display will
show current test (shown in black – if
more then one manoeuvre has been
performed then the best manoeuvre will
also be displayed in blue) the MVV rate,
the % variation between manoeuvres the
breath rate and an ATS quality warning for
the test session.
'Touch' Again to repeat the manoeuvre,
Reject to reject the current manoeuvre,
Results to display a list of indices, the
values obtained, % predicted where
applicable and also a quality statement
concerning the test session.
To meet the ATS quality criteria for a
Good blow the manoeuvre should last 15
