[Use of assisted forced ventilation of the lungs in patients during prolonged respiratory therapy].
A total of 338 patients were treated by prolonged forced ventilation of the lungs (AVL). The adult respiratory distress syndrome was detected in 78 patients. Control group consisted of 260 patients in need of prolonged AVL because of respiratory discomfort. Central hemodynamics was assessed by the Swan-Ganz balloon catheter. The advantages of assisted AVL are decreased resistance of the patient to the respirator, no suppression of muscular activity, decreased intrathoracic pressure, a lower probability of respiratory alkalosis or acidosis, and possibility of inspiration end positive pressure during spontaneous respiration. The shortcomings are poor reaction of trigger mechanisms to the beginning of a spontaneous act and rapid exhaustion of respiratory muscles in grave weak patients.
