FVC Test Starts for no
apparent reason
1. The minimum flow
required to start a test has
been exceeded.
2. Excessive electromagnetic
interference is affecting
the instrument.
1. Instruct the patient not to
move the handle abruptly,
which can cause air to flow
through the pneumotach
and start a test.
Turn off fans or close
heating and air
conditioning vents near the
test area. Close doors or
windows.

Delay pressing the “Start
New Test” button until just
prior to beginning the
maneuver.
2. Select a different location
or find and correct the
source of the interference.
