Background
preload-responsive, stroke, EEOt, increases cardiac preload
STROKE, SEPTIC SHOCK
Fluid responsiveness is defined as an increase in cardiac index (CI) in response to an increase in preload [Several functional hemodynamic tests for assessing fluid responsiveness have been introduced in clinical practice in the last few years [The EEOt is based on an interruption of mechanical ventilation at the end of expiration for 15–30 s. This maneuver increases cardiac preload, venous return, and stroke volume (SV) in preload-responsive patients. In one study [We conducted this study to assess (1) if there was a correlation between the changes in carotid Doppler peak velocity (CDPV) or in corrected flow time (cFT) and the changes in CI induced by a 20-s EEOt; (2) if EEOt-induced changes in CDPV and cFT predict fluid responsiveness in patients admitted to intensive care unit (ICU) with septic shock.
