Monitorización continua del shunt intrapulmonar mediante oximetría dual

We evaluated the modifications in gas exchange in 18 critical patients with acute respiratory failure after stepwise application of several levels of positive expiratory pressure (PEEP) by means of integrated and real time monitorization of arterial oxygen saturation (SaO 2 ) and, concomitantly, the continuous monitorization of oxygen saturation in pulmonary artery (SvO 2 )
