Optimizing Packed Red Blood Cell Transfusions: Viscosity, Volume, and Time
Tóm tắt
A straightforward formula,
$${V=({\frac{{H_i\cdot b}}{2}-1})\,{\cdot\,V_{_i}}}$$
which minimizes the product of transfusion time and volume has been derived. V
i represents the initial volume of the packed red blood cells (PRBCs) whereas H
i represents their initial hematocrit. The coefficient b is based upon an approximate exponential representation of viscosity as a function of added volume V and H
i. This formula allows for the minimization of both the volume of diluent, added to a known volume of PRBCs, as well as a minimization of the transfusion time.
