Once ports have been opened on a unit of blood, it must be used within?
system at 1 - 6 degree celcius has a shelf life of ?
6 anticoagulant additive solutions?
- Sodium Citrate
- Citric Acid
- Monobasic sodium phosphate
Preservative solutions are based on what?
FDA requirement that 70% of red cells (RBC) must survive 24 hours post transfusion.
Additive solutions must ensure what?
75% of RBCs survive 24 hrs post transfusion
Red Cell Products with Citrate Phosphate Dextrose (CPD or CP2D) Shelf Life ?
21 Days @ 1-6 °C
Red Cell Products with Citrate Phosphate Dextrose Adenine (CPDA-1 ) shelf life?
35 days @ 1 - 6 °C
Red Cell Products with
Additive systems: AS-1, AS-3, AS-5 shelf life ?
42 days @ 1 - 6 °C
pH blood storage lesion?
- Increase in [H+] as the RBC metabolize glucose
- pH drops over time
2,3 DPG blood storage lesion?
- ↓ in 2,3 DPG as pH decreases
- Release of O2 to tissues will decrease
Within 3-8 hours after transfusion previously stored RBC will regenerate what?
50% of normal 2,3 DPG levels
Does K+ decrease or increase in the unit as the red cells lyse over time?
Na/K+ blood storage lesion ?
Na/K pump will not function in the cold temperatures so K will not be pumped into the RBC
ATP storage lesion ?
Gradually decreases as RBC use for glycolysis
Donor Unit (BAG A) is centrifuged at a low speed (soft spin)
packed cells and platelet rich plasma (PRP)
PRP is expressed into the first satellite bag
The platelets are placed on a rotator or rocker bed to become ‘unpacked’
Platelets are stored at ?

- These are good for 5 days
The platelet poor plasma (PPP) is placed in the freezer and is FRESH FROZEN PLASMA.
- Good for 1 year at (-18C)
- Once thawed for transfusion, stored at 1-6C and good for 5 days.
- Fresh frozen plasma (FFP)
- Stored at -18C
-Thaw FFP at 4C for
-Hardspin of slushy product

outdate and storage temps ?
1 year @ (-18 °C)
PRBC will be good for
4 hours unrefrigerated or 24 hours in proper refrigeration
Units of platelets or cryoprecipitate that have been pooled to achieve an adult dose will be good for
4 hours only.
