METHOD FOR COMPENSATING A PRESSURE DROP IN A VENTILATOR TUBE, VENTILATOR AND MEMORY MEDIUM

摘要

The method compensates the pressure loss along the breathing hose (9), by measuring the air flow for a given pressure at the respiration device side of the breathing hose via an air flow sensor (16) and calculating a parameter for a function allowing calculation of the pressure loss from the air flow. The air flow is measured again with the breathing mask (18) fitted to the patient (19) and a required pressure which is the sum of the selected mask pressure and a correction pressure dependent on the calculated pressure loss is provided. Also included are Independent claims for the following: (a) a respiration device; (b) a memory medium storing a pressure loss compensation program for use in a continuous positive airway pressure respiration device.
