FIELD: medicine, medicinal equipment. ^ SUBSTANCE: one should carry out additional pulmonary ventilation at the background of stabilized positive end-expiratory pressure (PEEP). At expiration in case of PEEP one should expect a patient's independent respiratory attempt, moreover, it is necessary to compare the current PEEP value at permissible threshold value of pressure fluctuation in a patient's lungs to identify a patient's own respiratory attempt. Additional act of inhalation should be carried out at identifying a patient's own respiratory attempt or the time of inhalation delay achieved maximally permissible value. One should create PEEP by applying an effort that creates the pressure of respiratory mixture at inhalation line of respiratory contour, up to a reverse respiratory valve; one part of this respiratory mixture should be supplied towards the exit of respiratory contour for overlapping the expiration line and, additionally, it is necessary to force respiratory mixture into respiratory contour out of inhalation line, if the value of the pressure behind reverse valve of inhalation being below the pressure before reverse valve of inhalation. At the entrance of the reverse valve of inhalation respiratory mixture exists constantly. The innovation deals with additional pulmonary ventilation, compensation of leakages out of respiratory contour and maintaining constant level of PEEP at waiting for the onset of a patient's respiratory attempt at expiration. The innovation enables to automatically maintain the constant level of PEEP while waiting for a patient's respiratory attempt at expiration. ^ EFFECT: higher efficiency. ^ 5 cl, 2 dwg |
