[Experience in using artificial pulmonary ventilation with an inverse ratio of the respiratory-cycle phases in acute lung injury in the victims of severe wounds and mechanical damages]

Abstract

The possibility of using the methods of artificial pulmonary ventilation (APV) with positive pressure at the end of expiration (PPEE) and inverse ratio of the respiratory cycle phases for treatment of patients with grave wounds and mechanical injuries is assessed. PPEE is shown to have negative influence on gas exchange respiratory biomechanics and hemodynamics. The using of APV with inversed phases of the respiratory cycle allow to avoid the negative influence of APV on hemodynamics, improve the gas exchange and respiratory biomechanics indices as well as to reduce the amount of complications. The criteria are proposed showing when it is expedient to substitute the routine APV for the APV with inversed respiratory cycle phases.
