Why is citrate phosphate dextrose (CPD) is better than acid citrate dextrose (ACD) for storage of blood?
Because it is less acidic
Improves oxygen transpo
Hypeonicity of blood
More citrate ions
Citrate dextrose phosphate adenine (CDPA-1) helps in improving ATP synthesis during storage, thus increasing the shelf-life of storage up to35 days. Disadvantage of CDPA-1:Increases uric acid stone formation. Citrate phosphate dextroseImproves oxygen transpo Shelf life of the blood after adding above chemicals: - Acid citrate dextrose -> 21 days Citrate phosphate Dextrose -> 21 days Citrate phosphate Dextrose Adenine -> 35 days Saline Adenine Glucose Mannitol -> 42 days.
