Are dynamic changes of arterial waveform-derived variables more accurate than traditional static indices in predicting volume responsiveness in mechanically ventilated critically ill patients?
Dynamic arterial waveform variables provide highly accurate prediction of volume responsiveness in mechanically ventilated patients, outperforming traditional static indices.
: Dynamic changes of arterial waveform-derived variables during mechanical ventilation are highly accurate in predicting volume responsiveness in critically ill patients with an accuracy greater than that of traditional static indices of volume responsiveness. This technique, however, is limited to patients who receive controlled ventilation and who are not breathing spontaneously.
