WebMar 8, 2024 · In situations when PLR is limited, and a high risk of lung edema is present (high EVLW, high PVPI), one may use the mini-fluid challenge test—rapid bolus of 60–100 mL via a central venous catheter with simultaneous observation of VTI of stroke volume with the continuous method. WebDec 12, 2024 · The goal of fluid resuscitation is to increase the stressed blood volume and MCFP more than the CVP, and thereby increase the pressure gradient for venous return. However, hemodynamic effects of a fluid bolus (in the fluid responders) are short-lived, with the net effect being the shift of fluid into the interstitial compartment with tissue edema.
