Why Back Extrapolation?
A delayed start of the expiration in the forced expiration breathing
maneuver provides incorrect results for various parameters.
Back extrapolation means that in case of a delayed expiration the
system determines the correct start of expiration.

Why inspiratory back extrapolation?
In case of a delayed inspiration during the FIV1 breathing maneuver
and if “always“ is preset, the system determines the correct start of
inspiration.
