Evaluation the data behind using pulse pressure variation (ppv) as a method to predict fluid/volume responsiveness in resuscitation. Pulse pressure variation (ppv) in mechanically ventilated patients pulse pressure variation (ppv) is a dynamic hemodynamic parameter that predicts fluid responsiveness with high specificity (91%) and moderate sensitivity (72%) in mechanically ventilated patients, serving as a valuable tool for guiding fluid management decisions Monitoring arterial pressure variation, i.e
Spv/ppv, helps to answer the question of fluid responsiveness and can be used to guide fluid expansion therapy.4 spv/ppv parameters cannot, however, indicate what type of fluid is the most suitable for the therapy The medical practitioner who performs any procedure is responsible for determining and utilizing the appropriate techniques, devices and treatments for each individual. Experimental data suggest that ppv can still predict fluid responsiveness in cases of increased intraabdominal pressure but that the threshold value might be higher than in the case of normal abdominal pressure (59).
