title: [Computer evaluation of hemodynamic changes during mechanical ventilation with a body respirator].
abstract: The Authors study the variations of the cardiac output (C.O.), of the mean pulmonary arterial pressure (mPAP) and of the pulmonary vascular resistance (P.V.R.) in fine patients, affected by chronic respiratory failure, during the mechanical ventilation with a body respirator. In all the patients a reduction of the mPAP and of the CO are present. The PVR varies proportionally to the improvement of the respiratory indices. The Authors conclude that the haemodinamic changes are not exclusively due to the mechanical effect of the body respirator, but also to the correction of the respiratory situation and particularly due to the intra-alveolar pressure.
