4 hrs

2

system at 1 - 6 degree celcius has a shelf life of ?

24 hrs

3

6 anticoagulant additive solutions?

- Sodium Citrate
- Citric Acid
- Dextrose
- Adenine
- Mannitol
- Monobasic sodium phosphate

4

Preservative solutions are based on what?

FDA requirement that 70% of red cells (RBC) must survive 24 hours post transfusion.

5

Additive solutions must ensure what?

75% of RBCs survive 24 hrs post transfusion

6

Red Cell Products with Citrate Phosphate Dextrose (CPD or CP2D) Shelf Life ?

21 Days @ 1-6 °C

7

Red Cell Products with Citrate Phosphate Dextrose Adenine (CPDA-1 ) shelf life?

35 days @ 1 - 6 °C

8

Red Cell Products with
Additive systems: AS-1, AS-3, AS-5 shelf life ?

42 days @ 1 - 6 °C

9

pH blood storage lesion?

- Increase in [H+] as the RBC metabolize glucose
- pH drops over time

10

2,3 DPG blood storage lesion?

- ↓ in 2,3 DPG as pH decreases
- Release of O2 to tissues will decrease

11

Within 3-8 hours after transfusion previously stored RBC will regenerate what?

50% of normal 2,3 DPG levels

12

Does K+ decrease or increase in the unit as the red cells lyse over time?

Increase

13

Na/K+ blood storage lesion ?

Na/K pump will not function in the cold temperatures so K will not be pumped into the RBC

14

ATP storage lesion ?

Gradually decreases as RBC use for glycolysis

15

Donor Unit (BAG A) is centrifuged at a low speed (soft spin)
Produces what?

packed cells and platelet rich plasma (PRP)

16

PRP is expressed into the first satellite bag

Bag B

17

The platelets are placed on a rotator or rocker bed to become ‘unpacked’
Platelets are stored at ?

- (25C) and under constant agitation
- These are good for 5 days

18

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.

19

Bag C
