Abstract
The invention relates to a method and a device for treating Cheyne-Stokes respiration, periodic respiration and central or mixed apnea. If the respiration waxes and wanes periodically, there is pressure support in phases of periodic respiration, taking into account the natural patient respiration.
Claims15
A ventilator, wherein the ventilator comprises
- a controllable respiratory gas source for predetermining ventilation parameters in a respiratory gas supply of a patient with periodic respiration,
- one or more elements for establishing a measure of a current ventilation parameter of the controllable respiratory gas source,
- one or more first storage elements for storing a measure of a preceding ventilation parameter of the controllable respiratory gas source in a recallable manner,
- one or more first comparison elements for deriving a first measure of a change (increase/decrease) in a current ventilation parameter of the controllable respiratory gas source compared to a preceding ventilation parameter of the controllable respiratory gas source,
- one or more elements for establishing a measure of a current respiration, one or more second storage elements for storing a measure of a preceding respiration in a recallable manner,
- one or more second comparison elements for deriving a second measure of a change (increase/decrease) in a current respiration compared to a preceding respiration,
- one or more third comparison elements for deriving a third measure of a change (increase/decrease) in a respiratory exertion from at least one of the first and second measures, and
- a control apparatus which controls at least one ventilation parameter dependent on the third measure.
