Method of establishing the influence of short-term oxygen inspiration and a device for carrying out the method

摘要

Force-measuring device having the following functions: It measures the strength a) before the very short-term test inspiration of pure oxygen (or of air, where appropriate, having an increased oxygen content) and b) after the actual inspiration of pure oxygen. It measures the arterial (and, if appropriate, the venous) oxygen partial pressure (= PaO2) transcutaneously before and after the very short test inspiration of pure oxygen. It measures the systolic blood pressure - by means of an electronic blood pressure instrument integrated in the force-measuring device - specifically to take account of the damping effect which may result on transcutaneous measurement of the PaO2 at particular measurement values. It supplies pure oxygen or air with an increased oxygen content - by means of an oxygen source integrated in the force-measuring device - for the purpose of inspiration by the subject. Moreover, other devices required for application of pure oxygen or air with an increased oxygen content (e.g. pressure gauge and pressure reducer, humidifier, flow meter, O2 masks or goggles or T-pieces, and the like) are integrated in it. By means of a computer integrated in the force-measuring device it determines the individual time required by a specific subject for inspiration of pure oxygen or of air with an increased oxygen content in order to achieve clearly improved strength. The following must be taken into account when determining the duration of inspiration: a) PaO2 (or, where appropriate, ... Original abstract incomplete.
