Sir: We read with interest the study by Reuter et al. [
1] illustrating the influence of tidal volume (V
t) on stroke volume variation (SVV) evaluated by pulse contour analysis. The SVV—evaluated either by pulse contour or arterial pressure waveform analysis—has been proposed to assess the sensitivity of the heart to changes in cardiac preload (i.e. the slope of the Frank-Starling curve) and, hence, to detect fluid responsiveness in mechanically ventilated patients [
