SYSTEM FOR PROVIDING PRESSURE PULSES TO AIRWAY OF SUBJECT Russian patent published in 2018 - IPC A61M16/00 

FIELD: medicine.

SUBSTANCE: group of inventions relates to medical equipment. Pressure generation system comprises a pressure generator. System sensors are configured to generate output signals on the parameters of pressurised gas flow. Processors are configured to execute modules of a computer program. Respiratory event detection module is configured to detect airway obstruction based on sensor signals. Pulse parameter module is configured to determine gas pulse parameters. Pulse comprises a temporary portion of gas. Pulse is configured to open the airway of the subject. Pulse parameter module is configured to correct parameters of the current gas pulse to increase the efficiency of the current pulse with respect to the previous pulses based on the information transmitted by the output signals during the previous pulses. Correction consists in changing the amplitude, period or time characteristics of the pulse. Parameters of the current gas pulse are determined before the current pulse is formed on the basis of an analysis of the efficiency of previous pulses. Parameters of the current pulse determine the pulse from start to finish and include the amplitude, period and / or time characteristics of the first pulse parameter. Control module is configured to control the pressure generator to generate, in response to the detection of airway obstruction, a breathable gas pulse to be delivered to the airway of the subject in accordance with the received pulse parameters. Control module is configured to control the pressure generator to provide a minimum amount of positive pressure airway support. Control module controls the pressure generator to deliver a pulse in addition to supporting the airways with positive pressure. Method of generating pressure is disclosed.

EFFECT: technical result is generation of pressure to support pressure in the treatment of apnoea.
