title: [Comparative studies of the circulatory system during high frequency inspiratory ventilation and inspiratory positive pressure ventilation].
abstract: The studies were carried out in 14 dogs in which two different ventilation techniques were used under the general anaesthesia: HFIV and IPPV. Functioning of the cardio-vascular system was evaluated, basing on the measurements of pulse rate, pressure in the peripheral vessels, pulmonary artery and central venous pressure and calculation of the stroke volume, cardiac index, and pulmonary vessels resistance index. It was found that both techniques of ventilation did not exert any effect on the functioning of cardio-vascular system. Stroke volume was lower during IPPV than that during HFIV ventilation.
