antigen is found on
RBC
antibody is found
in plasma for the antigen that they do not have
A: antibody

immunogemic
most likely to cause reaction due to incompatibility
which blood system is most important
ABO
which blood system is 2nd important
Rh system
Rh antigens are
highly immunogenic
Rh+ can receive
Rh+
Rh-
Rh- can receive
Rh- only
when do Rh antibodies develop
after exposure
- transfusion
- pregnancy
main cause of hemolytic disease in newborn
Rh
which blood type is universal recipient
AB+
which blood type is universal donor

does the Rh matter for FFP

agglutination
occurs if antigen is mixed with its corresponding antibody
type and screen purpose
to detect antibodies commonly associated w/non-ABO hemolytic reactions
type and screen time
45-90 mins
incidence of reaction after T+S
<1%
type and cross purpose
- confirm ABO/Rh typing
- detects antibodies to other systems
- detects antibodies in low titers
type and cross time
15 - 60 mins
which blood test is mixing pt blood with donor blood
type and cross
incidence of reaction after T+C
~ 0%
what are donor bloods tested for
Hep B
Hep C
HIV
syphilis
blood donation preservative
CPDA-1
CPDA -1
Citrate
Phosphate
Dextrose
Adenosine
CPDA shelf life
35d
Citrate function
anti-coag
binds Ca2+
Phosphate function
buffer
Dextrose function
red cell energy source
adenosine function
precursor for ATP synthesis
best blood to give if you have it
whole blood
PRBC shelf life
35 days
PRBC effect
1 unit will raise :
Hg 1g/dL
Hct 3%
PRBC SE
citrate toxicity
hypothermia
hyperkalemia
decr 2,3-DPG
when is transfusion considered
Hg 6-10 g/dL
which pts need higher Hg
CAD
cardiopulm
cerebrovascular
elderly
how many donors are needed for 1 bag of plts
6-8
plt storage
20-24C
Plt effect
1 unit will raise plts by 5k-10k
plt indication
thrombocytopenia
plt dysfunction
is ABO compatibility req for plts
no
only prophyaltic indication for plts
TBI
FFP contains
plasma proteins
most clotting factors
