December 1, 2020 – Masimo announced the findings of a study published in the Ain-Shams Journal of Anesthesiology in which Dr. Diaaeldin Aboelnile and colleagues at Ain-Shams University in Cairo, Egypt compared two noninvasive methods of assessing fluid responsiveness in mechanically ventilated patients, dIVC and Masimo PVi.
Researchers found both methods to be “effective,” but determined that PVi was advantageous because of being “continuous, operator-independent, and more reliable than dIVC.” PVi (pleth variability index), is a measure of the dynamic changes in perfusion index that occur during the respiratory cycle.
Based on these findings, the researchers concluded, “The results of our study showed that assessment of PVi and dIVC noninvasively were good predictors for fluid management and responsiveness prediction using PLR technique in the surgical ICU mechanically ventilated patients.” They continued, “PVi and dIVC can be used in the assessment of fluid responsiveness of the intubated ventilated sedated patients with sinus rhythm in the ICU, and both methods are noninvasive and can be performed at the bedside, but PVi has the advantage of being continuous, operator-independent, and more reliable than dIVC.”
