Procedure for determination of gas content |
| abstract |
A method for determining the gas content, e.g. of oxygen in breathing gas in a breathing apparatus, the gas content being determined in the method from the speed of sound in the breathing gas, is described. In order to resolve the problems caused by temperature variations in gas samples, the method according to the invention comprises the step that determination of the speed of sound is synchronised with one or a plurality of specific times in a respiratory cycle. Determination can then be made when conditions are most stable. A breathing apparatus with a gas meter for performing the method is also described. <IMAGE> |
