Accuracy of stroke volume variation compared with pleth variability index to predict fluid responsiveness in mechanically ventilated patients undergoing major surgery.

Pleth variability index is a weak predictor of fluid responsiveness in patients receiving norepinephrine.

The second study evaluated pleth variability index in spontaneously breathing adults during regional anesthesia.

It is using Rohrscheib's Pleth LLC of Batesville, a Web development and marketing agency.

DPOP (Delta-POP or [DELTA]POP) is a physiological parameter calculated from the pulse oximeter signal--the photoplethysmogram or "pleth"--which measures the strength of respiratory modulations present in the waveform.

Respiratory variations in the photoplethysmographic waveform amplitude (APOP) and the pleth variability index (PVI) are proposed as noninvasive alternatives [2, 3].

Theoretically, the relatively frequent pleth oscillations (vasomotion) in micro-capillaries (smallest capillaries) overlap the less frequent heart rate dependent oscillations in macro-capillaries (largest capillaries).

Masimo (Nasdaq: MASI), Irvine, Calif., has announced that a new study published in the peer-reviewed journal Critical Care Medicine demonstrates that noninvasive, continuous monitoring of Masimo Pleth Variability Index (PVI[R]) predicts fluid responsiveness with high sensitivity (95%) and specificity (91%) in mechanically-ventilated patients in the Intensive Care Unit (ICU).(1) Multiple previous studies have shown that PVI predicts fluid responsiveness in surgical patientshelping clinicians improve fluid management to reduce patient risk,(2, 3, 4) but this is the first published study demonstrating its effectiveness in predicting fluid responsiveness in critically-ill ICU patients.

Where this unit also shines is in the data presented beyond Sp[O.sub.2] and heart rate--it shows perfusion index (PI), respiratory rate and pleth variability index.
