<p>The invention relates to a method for the automatic control of a ventilator machine for changing over (triggering) between successive phases of ventilation (inspiration and expiration phases), in which a pneumatic signal for breathing activity U pneu (t) and a non-pneumatic signal for breathing activity u non-pneu (t) from a patient are sensed and, as from a preset reference time after the beginning of the current phase of ventilation, the respective distances ” pneu (t) and ” non-pneu (t) from associated threshold values are determined and these distances ” pneu (t) and ” non-pneu (t) are standardised in relation to one another, to become ´ pneu (t) and ´ non-pneu (t), in such a way that their values are the same at the preset reference time, a mean is formed of the standardised distances ´ pneu (t) and ´ non-pneu (t) to give a mean distance, and a changeover is made to the next phase of ventilation when the combined distance is 0.</p> |
