Blood Transfusion Volume CalculatorCanineFeline

Calculate blood transfusion volume for dogs and cats. Estimates the volume of whole blood or packed red blood cells (pRBC) needed to raise the patient's PCV (packed cell volume) to a target level. Uses species-specific blood volume constants (90 mL/kg for dogs, 60 mL/kg for cats) and standard donor PCV values. Used for anemia management, surgical hemorrhage replacement, immune-mediated hemolytic anemia (IMHA), blood loss estimation, and emergency transfusion planning. Common query: 'how much blood does my dog need for a transfusion' or 'transfusion volume for anemic cat'.
