PPT-Blood Volume Analysis Can Distinguish True Anemia from Hemo

PY Van MD SD Cho MD SJ Underwood MS GJ Hamilton BS LB Ham MD MA Schreiber MD Background Hemorrhage leading cause of preventable death in trauma victims Decreased peripheral hematocrit pHct used as marker for blood loss. Mike Clark, M.D.. Anemia. is a decrease in the normal number of red blood cells (RBCs) or less than the normal quantity of hemoglobin in the blood. However, it can include decreased oxygen-binding ability of each hemoglobin molecule due to deformity or lack in numerical development as in some other types of hemoglobin deficiency.. Laboratory Procedures. Anemia. Defined:. A condition of reduced oxygen carrying capacity of erythrocytes. Erythrocyte disorders. May be associated with. : . Decreased production of . RBC’s. Increased destruction of . Hemolysis. is defined as the premature destruction of red blood cells (RBCs).. Anemia results when the rate of destruction exceeds the capacity of the marrow to produce RBCs. Normal RBC survival time is 110. Rafi Ahmed, MD. Hematology and Oncology Fellow. 4-10-14. Overview.

Decreased peripheral hematocrit (pHct) used as marker for blood loss. Anemia. True or absolute anemia is defined as a decrease in erythrocyte mass within the body. HCT, hemoglobin, and RBC count values are usually below their reference intervals.. Low erythrocyte parameters may also be present in blood when the total-body erythrocyte mass is normal (relative anemia). . Anemia is a condition in which the number of red blood cells or their oxygen-carrying capacity is insufficient to meet physiologic needs, which vary by age, sex, altitude, smoking, and pregnancy status.
