In this review we briefly discuss the physiological mechanisms responsible for arterial pressure generation with special focus on resistance compliance and pulse wave amplification phenomena. We also emphasize the utility of taking into consideration the overall arterial pressure set systolic diastolic mean and pulse pressures in order to define haemodynamic status better. Finally we review recent studies showing that quantification of respiratory variation in pulse and systolic arterial pressures can allow one to identify the mechanically ventilated patients who may benefit from volume resuscitation.
