Allowable Blood Loss Calculation Formula

Allowable Blood Loss Calculation Formula. The allowable blood loss (abl) is calculated using the formula initially described by bourke in anesthesiology 1974. Albumin**, hespan®, dextran®) 1 ml whole blood.

In order to calculate the allowable blood loss (abl) for your patient you first need to know the patients estimated blood volume (ebv), the patient’s hematocrit (hct), and the minimum hematocrit you’ll allow (mhct).
