Abstract
A device for the survey of the breathing ventilation and oxygen consumption has a mask M, worn by the person being examined, a control modulus that realizes a sample method of the breathing volume and of the turnover management, and a radio transmitter 25 that sends the signals to a fixed reception and elaboration unity UF. The device is portable due to the very small dimensions thereof, and very light due to the presence of a slow analyzer that has the advantages of the quick analyzers, by means of controlled turnover sampling that makes the micro mixing chamber 3 at fixed capacity equivalent to a dynamic chamber at variable capacity. At the end of each breathing action, when the air flow is annulled, the impulses due to the moment of inertia of the turbine 7 are suppressed by means of the pressure transducer 9 that identifies the annulment of the flow and corrects the signal still provided by turbine 7.
