Using Dynamic Variables to Guide Perioperative Fluid Management
Azriel Perel
Abstract
Dynamic variables that quantify the variations in the arterial pressure and plethysmographic waveforms during mechanical ventilation reflect fluid responsiveness. These variables may be helpful in identifying occult hypovolemia and in preventing unnecessary fluid administration.
