Red blood cells are produced in the bone marrow
. They carry oxygen
around the body. When a patient does not have enough red blood cells
to carry oxygen, anemia
( Chapter 13) is said to result. Symptoms such as fatigue, dizziness, shortness and tachycardia may be noticed.
CBC (complete blood count
) is usually done to check the hemoglobin. Blood transfusion
( Chapter 1) may be ordered by the doctor if anemia is severe.
