FIELD: medicine.
SUBSTANCE: group of inventions relates to medicine. System for pressure maintenance for generation and supply of respiratory gas flow into patient's airway contains pressure generator; gas pressure sensor; sensor of gas consumption and controller, connected with possibility of interaction with pressure sensors and consumption and control of pressure generator operation. Controller automatically identifies interface device by supplying multitude of pressures to interface device with application of system for pressure maintenance and determination of multitude of rates of output flow from interface device, determination of zero or minimal changes of output flow rate, corresponding to changes of level of supplied pressures, when multitude of pressures are higher than specified initial pressure, and comparison of particular rate of output flow and specified initial pressure with multitude of preliminarily determined rates of output flow and pressure points for identification if interface device. Particular flow rate corresponds to one of multitude of pressures, which is higher than particular specified initial pressure. Controller is made with possibility of regulating operation parameters of system for pressure maintenance or providing possibility of functioning of system for pressure maintenance on the basis of identification of interface device type. Method for identification of interface device is disclosed.
EFFECT: technical result consists in minimisation of inadvertent leak of respiratory gas taking into account of interface type.
