Brief Summary:
The waveform plethysmographic signal can be used to establish an index for predicting fluid responsiveness (∆POP: respiratory variation of the plethysmographic waveform of pulse oximetry). This index was validated in some studies and because of its non-invasiveness it seems very interesting in anesthesia.
However, in a previous study the investigators evaluated the correlation between the results provided by this index (∆POP) and those of the reference index (∆PP: pulse pressure variation), and the obtained results were significantly lower than what had been previously described. In this study, the index was calculated from a recording of a filtered signal. This unavoidable application of a filter on anesthesia monitors could contribute to the discrepancy between the ∆POP and the ∆PP.
The realization of a new study, comparing ∆PP and ∆POP obtained from an unfiltered plethysmographic signal, should answer the ∆POP ability to be used in place of ∆PP.
