Run quality check
The software will monitor P
ves
on cough peaks for 30 seconds. When a cough
peak is detected, the check will be performed and shown immediately. The
check is OK when there is a minimal 70% amplitude agreement between the
P
ves
and the P
abd
signals (the smaller spike must be at least 70% of the larger
spike). If EMG is being measured, the software will check whether the EMG
signal doubles during a cough. The result of the quality check is shown in a
message (Figure 2.24).

Results quality check OK
When no cough peaks are detected after 30 seconds, the message “no cough
detected” is displayed. When the check is not OK, the failed
channels are listed in the message box (Figure 2.25).
