Recently, several emergency cardiopulmonary bypass (ECPB) systems have been designed for the support of the arrested patient refractory to resuscitation. We have developed a compact ECPB system utilizing a Bio-Medicus centrifugal pump and a Bentley BCM-7 membrane oxygenator featuring rapid setup and prime. In contrast to other systems, our design provides a choice of configurations for ECPB which allow its continued use from initiation of membrane assist throughout any operative intervention. The safety and efficacy or this system has been tested using a canine model. Five animals were cannulated via the external jugular vein and the femoral artery, placed on ECPB (mean flow 80cc/kg/min), and monitored for 6 hours. Arterial and venous pressures and blood gases were easily maintained by standard manipulations. Serum hemoglobin, BUN, creatinine, and urine output remained stable at levels normal or bypass. Platelets, fibrinogen, and hemoglobin exhibited dilutional decreases at one hour, then stabilized. In summary, this system safely provides short term emergency metabolic and respiratory support while offering unique advantages in mobility, flexibility, and ease of use.
