EditorWe read with great interest the study by Solus-Biguenet and colleagues1 regarding the evaluation of fluid responsiveness using non-invasive predictors during major hepatic surgery. The authors compared the value of several indices of fluid responsiveness and concluded that the respiratory variations in arterial pulse pressure obtained from the invasive (PPVart) and FinapressTM (PPVfina) arterial pressure curves were the most accurate predictors of response to volume expansion. Moreover, they concluded that respiratory variations in the pulse oximetry waveform (PPVsat) were greater in responders than in non-responders to volume expansion even if the predictive value of this parameter was weaker than PPVart and PPVfina. These results are extremely interesting, as pulse oximeters are non-invasive, inexpensive, and are daily used in the operating theatre. Thus, the results from this study suggest that PPVsat may be a useful
