Study Summary
The purpose of this study is to determine how red blood cell transfusions, particularly the length of storage time of units of packed red blood cells, affects the cardiovascular function in patients receiving transfusions. This study will also determine the most ideal way of storing and processing blood, and assess how transfusion affects a person's ability to exercise and how their blood vessels relax and contract.
Primary Outcome
Brachial artery flow-mediated dilation (FMD) will be performed by using ultrasonography. The brachial artery of the non-dominant arm will be imaged using a high-resolution 13 MHz ultrasound transducer. A blood pressure cuff on the forearm will be inflated to supra-systolic pressures to produce 5 minutes of ischemia. After cuff deflation, imaging of the brachial artery will be performed continuously for the next 120 seconds and the flow-mediated dilation will be calculated. Change in FMD is the p
