In a method for adaptive triggering of respiratory phases in a breathing
device, and a breathing device operating according to the method, first
respiration indicator signal is determined based on at least one of the
parameters flow and pressure, the respiration indicator signal is compared
with a trigger requirement and a trigger signal is generated when the
respiration indicator signal fulfils the trigger requirement. In order to
shorten response times to respiration changes without losing stability, an
excitable cell signal related to respiration is measured, and a second
respiration indicator signal is determined based on the measured excitable
cell signal, and the trigger requirement is adapted in relation to the
second respiration indicator signal.
