FIELD: medical engineering. SUBSTANCE: device has means 2-4 for monitoring one or more physiological variable parameters like air flow and sound arising in respiration, electroencephalographic parameters, electrooculogram parameters, electromyogram parameters and/or patient position. The device has means 4 for receiving data describing physiological patient state and means 5 for determining gas pressure or medicament quantity required for essentially preventing the mention state worsening. Means for determining the values optionally have an algorithm for shaping gas pressure signal that essentially mismatches by 180 deg in phase with patient respiration phase and/or sound produced. The device has optional means 6 for supplying gas to patient corresponding to predefined pressure. The device has optional unit 7 for supplying medicament to patient. EFFECT: enhanced effectiveness of treatment; suppressed soft palate vibrations. 19 cl, 5 dwg
