SYSTEM AND METHOD FOR DELIVERY OF A RESPIRATORY GAS FLOW UNDER PRESSURE IN THE RESPIRATORY WAYS OF A SUBJECT USING STOCHASTIC FLUCTUATIONS

摘要

1. System (10), configured to deliver a stream of respiratory gas under pressure into the respiratory tract of a subject (12), wherein system (10) comprises: a pressure generator (14) configured to generate a stream of respiratory gas under pressure, so that one or more parameters of the gas flow of the respiratory gas under pressure provide therapeutic benefit for the subject (12); an interface circuit (16) of the subject, configured to deliver a stream of respiratory gas under pressure from the pressure generator (14) into the airways The object (12); as well as a mechanism (24, 26, 38) for pressure fluctuations made with the possibility of creating stochastic pressure fluctuations in the respiratory gas flow under pressure in the airways of the subject (12) or near them, while the mechanism for pressure fluctuations contains a processor (26), a module (38) fluctuations performed by the processor, as well as an element selected from the group consisting of (i) a valve (24) for pressure fluctuations, (ii) a component of a pressure generator (14), and (iii) a valve (24) for fluctuations pressure and component of the pressure generator (14), at The fluctuation module (38) is configured to (a) control the start and / or end of stochastic fluctuations, and (b) determine or set one or more of the following parameters: frequency range of stochastic fluctuations, average or median frequency of stochastic fluctuations, amplitude range of stochastic fluctuations fluctuations, average or median amplitude of stochastic fluctuations, the range of pressure levels in which stochastic fluctuations occur, as well as the maximum deviation from the average pressure level�
