Abstract

The invention relates to a device for assessing the applied air pressure during automatic respiration through positive airway pressure. The air pressure applied is varied by the device according to the invention so that at least three different pressure values can be adjusted. The corresponding respiratory gas flow is measured. On the basis of the relation of the measured respiratory gas flows to each other it is determined whether the applied air pressure is below or above an optimal air pressure or whether the applied air pressure is the optimal air pressure. The device according to the invention can be applied for adjusting the optimal air pressure in respirators used in the CPAP therapy. The device according to the invention provides the advantage of enabling an easy and reliable control of the applied air pressure.
