Erythrocyte Transfusion
Rejuvenated RBC and VO2 Max in Healthy Subjects
To compare the physiologic benefits of rejuvenated RBCs (rejRBCs) to standards RBCs (PRBCs), we will emulate critical conditions by safely maximizing stress on the cardiovascular system, in an elective, feasible volunteer study.
