method for evaluation of pulmonarem stress and atmungsvorrichtung

摘要

A method for assessing pulmonary stress, wherein a flow of respiratory gas is supplied to the lungs of a subject, an ensuing pressure is measured in relation to time and the pressure-time (P-t) relationship is analysed is disclosed. The method is characterised in that the analysis comprises the method step of determining the profile of the pressure-time (P-t) relationship. In short, the profile is straight (2A) when no stress is present, convex (2B) when there is a risk for overdistension and concave (2C) when alveolar units are opened up. Implemented in a breathing apparatus the method can be used to assist an operator in diagnostic and therapeutic considerations in relation to a patient. IMAGE
