Once the test has finished, the
display will show current test
(shown in black – if more than one
maneuver has been performed,
the best maneuver will also be
displayed in blue) the MVV rate,
the % variation between
maneuvers, the breath rate and
the ATS quality warning for the
test session.
Select ‘Again’ to repeat the
maneuver, ‘Reject’ to reject the
current maneuver, ‘Results’ to
display a list of indices, the values
obtained, % predicted where
applicable and a quality statement
concerning the test session.
To meet the ATS quality criteria
for a good blow, the maneuver
should last 15 seconds with a
breath rate greater than 65
breaths per minute. The ATS
reproducibility criterion is two
maneuvers with a good blow and
the MVV variability between
maneuvers should not exceed
20%.
