blood administration Flashcards
blood components
RBC, plasma, platelets, cryoprecipitate
cryoprecipitate
comes from plasma after freeze-thaw cycle
- mainly fibrinogen
- given to people with low fibrinogen
FFP
can be stored for a year
- does not provide platelets
- typical volume is 200-250
Rh
identifies whether a persons blood type is negative or positive
Blood group O antigen and antibodies
- no antigens on red cells
- anti A and anti B antibodies in plasma
blood group A antigen and antibodies
- “A” antigens on red cells
- anti B antibodies in plasma
blood group B antigen and antibodies
- “B” antigens on red cells
- anti A antibodies in plasma
blood group AB antigen and antibodies
- A and B antigens on red cells
- no antibodies in plasma
O negative compatibility to RBC and plasma
- compatible to O negative RBC
- can have any plasma
- universal RBC donor
O positive compatibility to RBC and plasma
- compatible to O + and O - RBC
- can have any plasma
A negative compatibility to RBC and plasma
RBC: A- O-
Plasma: A, AB
A positive compatibility to RBC and plasma
RBC: A+,A-,O+,O-
plasma: A and AB
B negative compatibility to RBC and plasma
RBC: B-, O-
Plasma: B and AB
B positive compatibility to RBC and plasma
RBC: B+,B-,O+,O-
Plasma: B and AB
AB negative compatibility to RBC and plasma
RBC: AB-,A-,B-,O-
Plasma: only AB
AB positive compatibility to RBC and plasma
RBC: universal receiver of RBC
Plasma: only AB
PRBC indications for use
- chronic or symptomatic anemia (fatigue, SOB, reduced O2)
- Restoration of blood volume
- dont treat with hemoglobin unless 70
- typical bag volume is 250ml
PRBC effect on hemoglobin and hematocrit
raises hemoglobin 1g/dL
raises hematocrit 3%
indication for administration of plasma
procoagulant deficiencies; DIC; trauma
indication for administration of platelets
control bleeding in platelet deficiency; thrombocytopenia
gauge sizing
22-14 appropriate but 20-18 better for general population
priming solution for blood
only use normal saline
