Assessment of this response by monitoring changes in some hemodynamic characteristics in relation to spontaneous breathing efforts would be very helpful for the management of the critically ill. This unfortunately remains a difficult clinical problem as discussed in the previous issue of the journal. Technical factors and physiological factors limit the usefulness of current techniques. It is becoming increasingly apparent that excess fluid is detrimental to patient outcome 1 and that there is a limit to volume responsiveness of the heart 2 . It would therefore be potentially useful to be able to predict when volume infusions will be futile for the management of critically ill patients. Perel and colleagues 3 followed by other workers 4 introduced the use of respiratory variations in systolic pressure for the prediction of fluid responsiveness methods of detecting these variations have even been automated with monitoring devices. Based on the presumed physiological mechanism 5 however the prediction was that that these techniques probably would not work in subjects with spontaneous efforts and this was indeed supported in an earlier study by Rooke and colleagues 6 . In the previous issue of Critical Care Heenen and colleagues 7 confirmed that pulse pressure variations .
