Comparative evaluation of the cardiorespiratory effects of assist control ventilation vs pressure support ventilation in patients following orthotopic liver transplantation.

Objective: 1) To compare the haemodynamic tolerance of ACV and PSV in patients mechanically ventilated after orthotopic liver transplantation; 2) to compare patients comfort during ACV and PSV.

Design: Prospective randomized cross-over study.

Setting: General ICU of the University of Rome "La Sapienza".

[Hemodynamic and respiratory aspects in orthotopic liver transplantation].

Intraoperative hemodynamic and respiratory data from one-year experience of orthotopic liver transplantation with veno-venous bypass (10 cases) were collected. Seven different phases of OLT was submitted to one way analysis of variance. Variability is due to degree and duration of liver disease.

Auto-PEEP and dynamic hyperinflation in COPD patients during controlled mechanical ventilation and high frequency jet ventilation.

We investigated the levels of auto-PEEP and dynamic hyperinflation during high frequency jet ventilation (HFJV) and controlled mechanical ventilation (CMV) in six patients with chronic obstructive pulmonary disease within the first 36 h of acute exacerbation. The comparative evaluation was performed at similar conditions of gas exchange in HFJV and CMV: PaO2 77.6 +/- 11 mmHg vs 80.
