摘要:
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 upneu(t) and a non-pneumatic breathing activity signal unon-pneu(t) of a patient are picked up. The intervals Δpneu(t) and Δnon-pneu(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 δpneu(t) and δnon-pneu(t), such that the intervals have equal interval values at a preset reference point in time. The standardized intervals δpneu(t) and δnon-pneu(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.
