Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
This is a single-center, randomized, partially blinded study to determine whether 42-day old red blood cells (RBCs) deliver oxygen as effectively as 7-day old RBCs and also to determine whether transfusion with 28-day old RBCs is non-inferior to 7-day old RBCs with respect to oxygen delivery. In this study, subjects will be randomized to be transfused with 2 units of autologous (one's own) RBCs that are either 7-, 28-, or 42-days old. Endpoints include changes in exercise duration and VO2 max (test of oxygen consumption/delivery) between groups.
