FIELD: medical technology.
SUBSTANCE: group of inventions relates to medical technology. The artificial lung ventilation (ALV) device contains a fluid supply unit, a fluid removal unit, and a control device designed to determine or additionally evaluate the course of the compliance curve area by supplying and /or removing the fluid medium and by determining the compliance value based on the expression: С=V/Δp, wherein V is the fluid medium volume, volume of fluid introduced into or removed from the airway when the airway pressure changes, and Δp is pressure difference. The control device is configured to determine and set on the ALV device, taking into account the determined or additionally estimated course of the compliance curve area, the position of the pressure interval with pressures P1 and P2 at which at least one ALV process, that is, inhalation and exhalation, occurs between these pressures P1 and P2 and the value of the compliance of this ALV process is the greatest. The control device is also configured to determine the compliance values and based on those to determine for at least one next ALV process the position of the pressure interval with pressures P1 and P2 and to supply and /or remove the fluid in at least one next AVL process in the set pressure interval. At all points during the artificial lung ventilation process, the ALV has the ability to continuously actively control the evacuation of fluid from the patient's lungs during exhalation. The specified active control includes a continuous change in the pressure of the withdrawn fluid, resulting in continuous control of the rate of the withdrawal of the fluid. An alternative version of the ALV device and options for operating an AVL device are disclosed.
EFFECT: technical result consists in providing individual setup and safety.
