Changes in red blood cell integrity related to infusion pumps: a comparison of three different pump mechanisms.


OBJECTIVE To study the effects of three different infusion pumps on red blood cell (RBC) integrity. SETTING Laboratory. INTERVENTIONS Transfusion of packed RBCs using three different pumps (syringe pump, conventional peristaltic pump, and a new volumetric pump with shuttle mechanism). Flow rate was set at 20 mL/hr and duration was 2.5 hrs, simulating a… (More)
