More than 5% or 0.1 liters of exhalation occurred
before the back extrapolated starting point (ATS
specification,,). To correct this, the patient should
blast out harder at the beginning of the maneuver.
The flow stopped abruptly. To correct this, the
patient should keep blowing longer until all air has
been expelled.
The patient coughed during the maneuver, or flow
was interrupted or uneven. Have the patient remove
his or her dentures and/or advise the patient to
refrain from coughing. Sometimes a glass of water
will help.
Each of the three calibration maneuvers was within
0.5% of the average. The existing calibration factor
will be replaced with the calibration factor from this
calibration.
The effort was acceptable--one with no obvious
faults.
The effort was acceptable.
This test has an FVC and FEVl within 5% (or an
MVV within 15%) of the existing BEST test.
This test has a lower FVC or FEV1 by at least 5%
(or lower MVV by at least 15%) and will not replace
the existing BEST test. To correct this, inhale more
fully before exhaling, and blast out harder at the start
(FVC), or pant more rapidly and deeply (MVV).
