Question

Why do patients suffering from anemia generally not exhibit an increase in respiratory rate or tidal vol. even though their blood is not carrying adequate oxygen.

Answer 1

An increase in respiratory rate or tidal volume may effect the abount of oxygen in the blood.  Anemia is not the result of a lack of oxygen, it is the result of blood cells that carry oxygen.  The lack of blood carrying oxygen is a symptom, not a disease in an of itself.  It can be caused by many things including an insufficient number of red blood cells, a low hemoglobin content and abnormal hemoglobin, just to name a few.
