light (soft) spin
To separate red cells from platelet-rich plasma (PRP)
a hard spin
To concentrate platelets into a button and leave platelet-poor plasma at the top
shelf life of pooled random platelets
Typically expire after 4-5 days from the time of pooling
common uses of apheresis
Collecting platelets or plasma for transfusions, treating conditions by removing harmful
components, and stem cell harvesting
What is apheresis?
A medical procedure that removes whole blood, separates it into components, and returns the
desired component or removes harmful substances
What is leukapheresis?
Apheresis procedure that removes white blood cells from the blood
What is plateletpheresis?
Apheresis procedure that collects platelets from the blood
What is plasmapheresis?
Apheresis procedure that collects plasma from the blood
What is erythrocytopheresis?
Apheresis procedure that collects red blood cells from the blood
,whole blood
Unseparated blood collected into an approved container containing an anticoagulant
preservative solution
What is cryoprecipitate?
A protein-rich product derived from fresh frozen plasma that contains high concentrations of
fibrinogen and clotting factors
required temperature for storing whole blood after collection
At room temperature or on cool packs (not frozen)
What are the donor requirements for blood donation?
Typically 17+ years old (or 16 with parental consent) and at least 110 lbs, feeling well, and
hydrated
What is the role of the buffy coat in blood components?
It contains white blood cells and some platelets and
anticoagulants such as citrate during apheresis
To prevent clotting in the machine
What is Fresh Frozen Plasma (FFP)?
Plasma frozen within eight hours of collection
What happens to the remaining blood after apheresis?
It is returned to the patient, often with a replacement fluid like saline or albumin
What is the shelf life of whole blood?
21 days
What is the storage temperature range for whole blood?
1°C to 6°C
What anticoagulant is used in the ACD-A formula?
Acid-citrate-dextrose formula A (ACD-A)
What is the maximum volume collected per blood donation?
450-500 mL
, What are Packed Red Blood Cells (PRBCs) primarily used for?
To carry oxygen for patients with anemia or significant blood loss
What is the shelf life of PRBCs with modern additive solutions?
Up to 42 days
volume of a unit of PRBCs
Around 200-250 mL of red cell in a unit
leukoreduced PRBCs
They are filtered to remove most white blood cells
What are the storage conditions for platelets?
20-24°C room temp with constant gentle rocking
minimum platelet count required for random-donor platelets
At least 5.5 × 10^10 platelets AND MUST be prepared in 8 hrs of collection from whole blood
donation
first soft spin = platelet rich plasma
2nd hard spin = separates plt from plasma
minimum platelet collected from apheresis
3 x 10^11 PLATELET
What is the shelf life of platelets?
Up to 5 days from collection days
What is the risk associated with room temperature storage of platelets?
Increased risk of bacterial growth
What is the purpose of apheresis in platelet donation?
To collect a concentrated dose of platelets from a single donor
What is the equivalent platelet yield of a single donor platelet (SDP) donation?
Equivalent to 5-10 random units
the processing requirement for collected plasma
It must be frozen within 24 hours
