a drop in 1+ of what 3 blood components characterizes anemia?
|
anemia = decreased HGB, HTC, or RBC mass
|
|
|
the SOB of anemia is caused by _______
|
decreased O2 carrying capacity of the blood "tissue SOB"
|
|
|
severity of anemia is related to HGB/HTC release. Decrease below what values of HGB and HTC indicate anemia in men? In women?
|
Males: HGB = <13g/dl & HCT <39%; Females: HGB = < 12g/dl & HCT <36%
|
|
|
what are the 3 main reasons for having anemia? 1) _______ loss, 2) decreased ____________, 3) short _________ (______) of RBCs
|
1) blood loss, 2) decreased production, 3) short survivial (hemolysis)
|
|
|
what 3 phases of RBC of the production process can be interrupted to cause anemia? Name of the few of the diseases that impaired production causes.
|
Phases: prolif, diff, and mat; diseases: aplastic anemia, megaloblastic anemia, iron deficiency anemia, anemia of chronic disease, myelophthisic anemia, anemia of renal failure
|
|
|
decreased Hb could be due to blood loss, what should be checked?
|
stool for occult blood (if chronic and slow, may not be visible to pt)
|
|
|
decreased Hb could be due to underproduction what values should be looked at?
|
retic count (should be dec'd); RBC indexes and bm are "informative"
|
|
|
decreased Hb could be due to hemolysis (uncommonly); what will the retic count, bilirubin, haptoglobin, and RBC morphs look like?
|
1) retic count: inc'd; 2) bilirubin: inc'd; 3) haptoglobin: dec'd; abnormal RBC morph
|
|
|
name some of the acute sx's of anemia
|
due to hemolysis/hemorrhage, so see: orthostatic hypoTN, tachycardia, shock
|
|
|
name some of the chronic sx's of anemia
