The maneuver was interrupted by the press of a key
or a low battery.
The FVC or MVV maneuver did not start within 20
seconds after the beep.
The FVC terminated normally, but on analysis, no
exhalation was found.
The maneuver appeared too fragmented, did not
have enough breaths to analyze, or the breaths were
too inconsistent or uneven. The maneuver analysis
routine failed; the PneumoCheck was unable to
analyze the data.
The PneumoCheck is establishing a baseline for
future data for calibration. In the RETRIM mode, the
PneumoCheck uses a more accurate (and lengthy)
approach than in the STEADY mode. The RETRIM
message will be displayed for about 45 seconds.
The PneumoCheck is transmitting an FVC test to the
Printer/Charger.
The PneumoCheck is transmitting an MVV test to
