  • RESPIRATOR WITH AUTOMATICALLY CONTROLLED PRESSURE-ASSIST RESPIRATION
    Publication number: 20100307499
    Abstract: A respirator with an adjustable pressure or volume flow curve has a control and analyzing unit, which is set up to determine the resistance R and the alveolar pressure Palv(t). The control and analyzing unit checks the functional dependence of Palv(t) and of the tidal volume Vol(t) for time intervals in which an indicator of the quality of a linear functional dependence of Palv(t) and Vol(t) meets a preset threshold criterion and to determine the elastance E or compliance C from the rise of the alveolar pressure Palv(t) as a function of the volume Vol(t) only in the time intervals thus determined.
