1 Pleth variability index to monitor the respiratory variations in the pulse oximeter plethysmographic waveform amplitude and predict fluid responsiveness in the operating theatre  M. Cannesson, O. Desebbe, P. Rosamel, B. Delannoy, J. Robin, O. Bastien, J.-J.

2 Fig 1 Pleth variability index (PVI) and perfusion index (PI) evolutions during volume expansion in a responder to volume expansion and in a non-responder to volume expansion. PVI (blue line) and PI (red line) evolutions during volume expansion. Black arrow shows volume expansion beginning and red arrow shows volume expansion ending. Volume expansion was performed over a 10 min period. We observed a PVI value of 21% at baseline in the responder patient. This value decreased progressively to reach 9% after volume expansion. In the non-responder patient, baseline PVI was 9% and PVI after volume expansion was 6%. At the same time, we observed a steady PI value in both patients.
