1. A method for adaptively triggering respiration phases in a breathing device, comprising the steps of:

  • providing exclusively pneumatic breathing assistance to a patient via a tubing system connected to a breathing circuit in which the patient participates;

    determining a first respiration indicator signal in said breathing gas circuit based on at least one parameter selected from the group consisting of flow and pressure in said breathing gas circuit;

    comparing said first respiration indicator signal with a trigger requirement in said exclusively pneumatic breathing assistance;

    generating a trigger signal to trigger a respiratory phase in said exclusively pneumatic breathing assistance when said first respiration indicator signal satisfies said trigger requirement;

    measuring an excitable cell signal related to respiration in said patient participating in said breathing gas circuit;

    determining a second respiration indicator signal based on the measured excitable cell signal; and

    adapting said trigger requirement dependent on said second respiration indicator signal.
