Description
Kentaro Okamoto and colleagues ask, in a 2026 intensive care study, whether a red cell transfusion truly raises venous oxygen levels in heart surgery patients, a common bedside hope. The measure, SvO2, balances oxygen supply against body use, but a rise does not always mean tissues fare better.
Records covered 1,352 patients given one unit with starting hemoglobin at or above 7.5 in the study rules. Hemoglobin rose modestly, yet average SvO2 barely moved, gaining just 0.08 points in the paired figures. Patients starting with low SvO2 were far likelier to respond, and each point higher at start cut response odds. Starting level alone predicted response moderately well, guiding smarter transfusion calls.
