What is Anemia?
 Deficiency in the oxygen-carrying capacity of the blood due to a diminished erythrocyte mass.
 May be due to:
- Erythrocyte loss (bleeding)
- Decreased Erythrocyte production
 low erythropoietin
 Decreased marrow response to erythropoietin
- Increased Erythrocyte destruction (hemolysis)

Measurements of Anemia
 Hemoglobin = grams of hemoglobin per 100 mL of whole blood (g/dL)
 Hematocrit = percent of a sample of whole blood occupied by intact red blood cells
 RBC = millions of red blood cells per microL of whole blood
 MCV = Mean corpuscular volume
- If > 100 → Macrocytic anemia
- If 80 – 100 → Normocytic anemia
- If < 80 → Microcytic anemia
 RDW = Red blood cell distribution width
- = (Standard deviation of red cell volume ÷ mean cell volume) × 100
- Normal value is 11-15%
- If elevated, suggests large variability in sizes of RBCs

Symptoms of Anemia
 Decreased oxygenation
- Exertional dyspnea
- Dyspnea at rest
- Fatigue
- Bounding pulses
- Lethargy, confusion
 Decreased volume
- Fatigue
- Muscle cramps
- Postural dizziness
- syncope

Special Considerations in Determining Anemia
 Acute Bleed
Drop in Hgb or Hct may not be shown until 36 to 48 hours after acute bleed (even though patient may be hypotensive)
 Pregnancy
- In third trimester, RBC and plasma volume are expanded by 25 and 50%, respectively.
- Labs will show reductions in Hgb, Hct, and RBC count, often to anemic levels, but according to RBC mass, they are actually polycythemic
 Volume Depletion
Patient’s who are severely volume depleted may not show anemia until after rehydrated
