[A method of decreasing accidental positive exhalation pressure upon high frequency artificial respiration of newborn infants].
A simple method has been suggested for the reduction of excessive positive end-expiratory pressure (EPEEP) occurring during high-frequency ventilation with positive pressure in the newborn. The method employs a special conntecor with an inner diameter decreasing towards the end of the tube included into the inspiration line. The use of a connector during high-frequency jet ventilation of lung models from newborn with hyaline membrane disease and meconial aspiration reduced effectively EPEEP in the proximal end of the intubation tube. However, the same efficacy of EPEEP reduction in the lungs has been observed only on the model of hyaline membranes. On the models of lungs from newborn with meconial aspiration EPEEP reduced insignificantly. With the increase in gas mixture flow, the efficacy of the device enhanced.
