... In recent years, there has been a trend toward the use, in intensive care units (ICUs) and in operating theatres, of ‘minimally invasive’ haemodynamic monitoring systems for the continuous ... accuracy and precision in conditions of haemodynamic stability, or during changes in intra- vascular volume in the absence of signifi cant variation in vascular tone, and so...

... easily obtained and continu- ously measured with the arterial waveform analysis method in a busy intraoperative setting. Together with adequate hemoglobin lev els and arterial oxygen satura- tion, ... hospital discharge only. Conclusions The results of this study demonstrated that an optimiza- tion protocol based on flow-related hemodynamic para- meters obtained with the minim...
