We conducted a randomised prospective open cross over trial on 44 patients with acute respiratory failure in the general intensive care unit of a university hospital. After a stabilization period of 8 h a cross over trial of 2 X 2 h was conducted. Apart from the PRVC VC mode ventilator settings were comparable. The following parameters were recorded for each patient days on ventilator failure in the assigned mode of ventilation peak inspiratory pressure 50 cmH2O and survival. Results In the crossover trial peak inspiratory pressure was significantly lower using PRVC than with VC 20 cmH2O vs 24 cmH2O P . No other statistically significant differences were found. Conclusions Peak inspiratory pressure was significantly lower during PRVC ventilation than during VC ventilation and thus PRVC may be superior to VC in certain patients. However in this small group of patients we could not demonstrate that PRVC improved outcome. intensive care mechanical ventilation respiratory failure Introduction During mechanical ventilation the application of positive pressure with a peak inspiratory pressure PIP in excess of 50-60 cmH2O may result in a barotrauma 1 . Gross overinflation leads to rupture of the airways which may result in pneumothorax pneumomediastinum or subcutaneous emphysema. Animal experiments have established that even PIP at a level of 30-40 cmH2O results in lung overinflation and may
