EDECMO 44: Bob Bartlett: Peristaltic Pumps, Hollow Fibers, and the History of ECMO

1 In this episode, Zack Shinar interviews Dr. Bob Bartlett from the University of Michigan.  Dr. Bartlett has revolutionized the world with his leadership and innovation from the very beginnings of ECMO.  Zack and Bob discuss the history of ECMO and the prior use of roller pumps and bubble oxygenators.  They go on to describe the advantages of centrifugal pumps and hollow fiber oxygenators.  Additionally, they talk about PMP (polymethylpentene)-coated membranes inside oxygenators and their improved ability to safely oxygenate blood.  They discuss anticoagulation and how Bob believes that direct thrombin inhibitors are superior.  They wrap it up with a discussion on the future of ECMO and how peristaltic pumps have some significant advantages2. 3,4 References 1.
