CPB FMEA #3: Heat exchanger leak in the oxygenator or cardioplegia heat exchanger.

This week’s FEMA is prompted by the recent chatter on the list servers about cleaning heater/coolers (H/C). The discussion centered on two aspects: 1) how to clean the water reservoir to kill microbial contamination without damaging the equipment and 2)… Read More

What Are The Native Reservoir And The Ready Reservoir?

Yes, it is possible to to ‘dry out’ a patient during cardiopulmonary bypass (CPB). The article (referenced below) is about pediatric patients, but I believe there is an adult correlation as well. What I learned is that patients coming off… Read More

Should Perfusionists Use a Transfusion Trigger on Cardiopulmonary Bypass?

I recently attended both the New Advances in Blood Management (NABM) and the Society for the Advancement of Blood Management (SABM) in Kansas City in 2009.  At both meetings the consensus was that a low hematocrit is bad and a… Read More

How Ultrafiltration And MUF During Cardiopulmonary Bypass Really Work!

  The mechanical separation of capillaries by edema decreases perfused capillary density which disrupts the oxygen pressure field. This can impact most of the soft tissues and organ systems in several ways and is frequently associated with organ failure. For… Read More

Perfusion Theory is an educational platform for the Oxygen Pressure Field Theory (OPFT). August Krogh’s theoretical concept of the oxygen pressure field is explained and then applied to clinical applications in perfusion practice.
