The purpose of this study is to look at red blood cell(RBC)transfusions in trauma patients and evaluate for any differences between the age of the RBCs and how they were stored. The investigators will specifically look for the following differences between study groups:

  1. the transfused red blood cells' ability to delivery oxygen to the tissues
  2. changes in the how the RBCs' look or act under a microscope and
  3. how the subject's internal organs are working and if they develop any infections
