As patient effort decreases, AVAPS automatically increases PS to
maintain the target tidal volume. The IPAP level will not rise above
IPAP Max, even if the target tidal volume is not reached. Conversely,
as patient effort increases, AVAPS will reduce PS. IPAP will not fall
below IPAP Min, even if the target tidal volume is exceeded.
If the Ramp function has been activated, it will take precedence over
the AVAPS feature. Once ramp is complete, AVAPS will resume.
