Abstract: FIELD: medicine. 
     SUBSTANCE: invention relates to medical technology, namely to a method of forced ventilation with the removal of excess moisture from the patient's respiratory tract. During the treatment procedure, a positive pressure Ip is formed in the respiratory tract during inhalation, and a negative pressure Ep is formed during exhalation. Prior to the treatment procedure for forced ventilation of the respiratory system with the removal of excess moisture, the preliminary stage of registering the oxygen content in the patient's blood is carried out and during ten breathing cycles “inhale/pause/exhale”, the individual parameters of the patient's independent breathing are recorded. At each cycle, the following parameters are recorded: Ti - the time of inhalation, Tp - the time of pause between inhalation and exhalation, Te - the time of exhalation, Vi - the volume of air during inhalation, Ve - the volume of air during exhalation. The following breathing cycles are performed forcibly based on the average values of the patient's breathing parameters: Ticp - the time of inhalation, Trsr - the time of pause between inhalation and exhalation, Tesp - the time of exhalation, Vicp - the volume of air during inhalation, Vecp - the volume of air during exhalation. The treatment procedure for forced ventilation of the respiratory tract and removal of excess moisture from the patient's respiratory tract is carried out in the first or second mode of the intensity of the procedure. In the first mode of the intensity of the treatment procedure, the starting value of the positive pressure Ip in the inhaled air flow for the duration of inhalation is set to Ip=10 hPa and the starting value of the negative pressure Ep in the exhaled air flow for the duration of exhalation is set to Ep=15 hPa. Then, starting from the second cycle of breathing, the values of the parameters Ip and Ep are increased in each subsequent cycle by 5 hPa to the level when the current value of the volume of forced exhalation reaches four times the value of Vecp when the patient breathes independently. In the second mode of the intensity of the treatment procedure, the starting value of the positive pressure Ip in the inhaled air flow for the duration of inhalation is set to Ip=15 hPa and the starting value of the negative pressure Ep in the exhaled air flow for the duration of exhalation is set to Ep=25 hPa. Then, starting from the second cycle of breathing, the values of the parameters Ip and Ep are increased in each subsequent cycle by 10 hPa to the level when the current value of the volume of forced exhalation reaches eight times the value of Vecp when the patient breathes independently. The treatment procedure is carried out with a constant registration of the oxygen content in the patient's blood.   
     EFFECT: expansion of the arsenal of technical means that provides an increase in the efficiency of forced ventilation of the respiratory system with the removal of excess moisture.
