Abstract
A process is provided for the automatic control of a respirator for changing over (triggering) between consecutive phases of respiration (inspiration and expiration phases), wherein a pneumatic breathing activity signal u(t) and a non-pneumatic breathing activity signal u(t) of a patient are picked up. The intervals Δ(t) and Δ(t) to the associated threshold variables are respectively determined starting from a preset reference point in time since the beginning of the present phase of respiration. The intervals are standardized to one another at δ(t) and δ(t), such that the intervals have equal interval values at a preset reference point in time. The standardized intervals δ(t) and δ(t) are averaged to a mean interval indicator and a changeover is made into the next phase of respiration when the combined interval indicator is 0.
