Anemia I Flashcards
proteins on membrane of RBC
spectrin
actin
increases RBC affinity for hemoglobin
decrease temp
decrease DPG
increase pH
decreases RBC affinity for HB
increase temp
increase DPG
decrease PH
two general ways to become anemic
decreased production
or increased destruction
MCV equation
%HCT x 10/RBC
MCH normal
27-34
MCHC normal
32-37
RDW normal
11.5-14.5
normal reticulocyte count
1%
increased RDW
ansiocytosis
increased variability in RBC size
polychromasa
indicates a shift in marrow reticulocytes nto the periphery in response to increase stimulation (aka increased epo)
you want to have increased reticulocytes when..
anemic
to show that your body is trying to compensate
reticulocyte production index
tells you if the bone marrow is adequately compensating for the degree of anemia
RPI equation
reticulocyte percentage x (HCT/normal HCT)/ maturation factor (days n marrow)
> 2: adequate response
<2: inadequate response
maturation term def and normal
maturation time of RBCs in days at various levels of anemia
normal = 1
