If done before 14 days may cause high 2,3-DPG which impairs O2 up-take. AS-3 and AS-5 cannot be rejuvenated Deglyced RBCs storage and description - Answer-37C warmer or waterbath (20-25 minutes) washed with solutions of decreasing osmolarity to avoid hemolysis. must remove cryoprotectant agents, minimial free hgb, and result in recovery of at least 80% RBC volume. open system:1-6C with 24 hr expiration. closed system: 14 days or as FDA approved What should the osmolality of a deglyced unit be? - Answer-500. Osmolality is a fxn of free glycerol therefore an increase is a result of improper deglycing What should free hgb in last wash be from decglyed unit? - Answer-200 Washed RBCs storage - Answer-1-6C washed with sterile normal saline to remove most of plasma 24 hour expiration FFP storage and description - Answer-prepared from WB or collected using apheresis. frozen at -18C or below contains max levels of labile or nonlabile coag factors Thaw between 30-37C Thawed plasma - Answer-FFP thawed but not transfused within 24 hrs can be stored 1-6C for 5 days reduction in Factors V and VIILiquid plasma - Answer-plasma separated from WB at any time during storage, up to 5 days after the expiration date of WB. supernatant levels of potassium and ammonia are increased Cryo - Answer-prepared from WB collected into CPDA-1 or CPD precipitates when FFP thawed between 1-6C stored at -18C or colder suspended in less than 15mL plasma contains factor VII and fibrinogen and most of XIII single unit store at 20-24 for 6 hrs pooled store at 20-24 for 4 hours
