A fluid responder can still be the wrong patient to give fluid
Lede: Fluid responsiveness tells you whether stroke volume will rise—not whether the patient can safely absorb more volume.
Why it matters
A patient with ARDS, acute kidney injury, venous congestion, or right-ventricular dysfunction may be preload responsive and still be fluid intolerant. In that setting, a higher cardiac output can come at the cost of worse pulmonary edema, renal venous pressure, or ventricular interdependence.
The pearl
Responsiveness is necessary, but not sufficient. Give fluid only when there is evidence of hypoperfusion, demonstrable responsiveness, and acceptable tolerance.
