Objectives:
Stroke volume variation and pulse pressure variation do not reliably predict fluid responsiveness during low tidal volume ventilation. We hypothesized that with transient increase in tidal volume from 6 to 8 mL/kg predicted body weight, that is, “tidal volume challenge,” the changes in pulse pressure variation and stroke volume variation will predict fluid responsiveness.
