Abstract
A respiratory apparatus comprises, in the direction of flow of gas, a high frequency valve (3), a respiratory gas heater (4) and a jet outlet (5). Between the heater (14) and the outlet (5), steam from a steam generating device (10, 14) is injected via steam line (9) into a respiratory gas line (2) this injection being carried out as a function of the respiratory gas pulses. The steam has a high temperature and water content, making it possible to ensure-a high relative moisture in the expanded respiratory gas mixture at the desired temperature of 37 DEG C. Only a low heat capacity is required for further heating of the respiratory gas. The low volume in the respiratory gas and the steam line guarantee the sharpness of the high frequency pulses in the respiratory gas mixture. <IMAGE>
