摘要：
FIELD: medicine.SUBSTANCE: breathing system containing a patient interface and a CPAP pneumoelement, in accordance with which, a damp air-oxygen breathing mixture is made up and supplied to the breathing system. The desired value of the breathing mixture constant overpressure at the respiratory circuit output is specified, the actual pressure of the breathing mixtures on the output of this circuit is measured, the measured and the specified pressure values are compared, the value of misalignment is determined, then breathing mixture flow control signals are formed continuously and output to control the flow until the said misalignment is eliminated. At that, the control signals frequency is significantly higher than the frequency of patients respiratory cycles. At that, it is supplemented with the following new operations: for a specific interacting breathing system, this system is automatically tested and during the testing process, values of the two correction factors are calculated and stored: the first factor characterizing the time constant of the CPAP pneumoelement and the second factor characterizing the air resistance of the breathing system. Then, taking into account the calculated values of the correction factors, the required value of the constant excess pressure at the breathing system output is clarified and stored, proceeding from the requirement that during the entire respiratory cycle, including during inspiration, it should not fall below atmospheric pressure, then the flow rate of the breathing mixture is controlled, such that the value of the excess pressure at breathing system output is maintained substantially constant and equal in magnitude to the refined predetermined value during the entire respiratory cycle. The device for method implementation includes a breathing mixture flow control module comprising the first controllable valve, a control unit, an information input and display module, a pressure pneumatic duct with a breathing mixture hu
