  • One unit of PRBC contains 200–300 mL, one unit of plasma contains 200 mL and one unit of platelets (from eight donors or apheresis from one donor) contains 180–350 mL.

  • ACH, acute care hospital; HR, heart rate; PRBCs, packed red blood cells; REBOA, resuscitative endovascular balloon occlusion of the aorta; SBP, systolic blood pressure (lowest registered during acute incident); TCH, tertiary care hospital.
