Comparing Dynamic Compliance Values
If you compare the dynamic compliance value (COMP) from the ventilation calculations with the
value from the Spirometry measurement you may see a difference. This comes from the different
The algorithm in the ventilation calculations takes into account only two sets of paired AWP/
AWV data: those from complete expiration and complete inspiration, when AWF is zero.
The algorithm in the Spirometry application takes into account all sets of paired AWP/AWV data
(125 Hz sampling rate), over one complete breath cycle, and calculates an "averaged" compliance
using a least square method.
