Summary
About the episode:
Cardiopulmonary resuscitation, or CPR, has been the gold standard for buying time in a medical emergency. But it's not very effective, especially for the majority of cardiac arrest cases. What is much more effective: employing advanced machinery like ECMO, extracorporeal membrane oxygenation, that can keep people alive for hours or even days and weeks while physicians address the medical emergency and the body heals. But can emergency medicine shift to get more patients on ECMO faster?
Guest:
Dr. Demetris Yannopoulous is a professor of medicine at the University of Minnesota Medical School where he is the director of resuscitation medicine.
Host:
Stephanie Desmon, MA, is a former journalist, author, and the director of public relations and communications for the Johns Hopkins Center for Communication Programs, the largest center at the Johns Hopkins Bloomberg School of Public Health.

| 0:00.0 | Welcome to Public Health On Call, a podcast from the Johns Hopkins Bloomberg School of Public Health, |
| 0:05.9 | where we bring evidence, experience, and perspective to make sense of today's leading health challenges. |
| 0:16.3 | If you have questions or ideas for us, please send an email to public health question at jhhhu.edu. |
| 0:23.8 | That's public health question at jhhu.edu for future podcast episodes. |
| 0:31.9 | This is Lindsay Smith Rogers. |
| 0:34.4 | Today, a look at the effectiveness of CPR, the gold standard technique when health professionals or members of the public are attempting to resuscitate someone in cardiac arrest. |
| 0:44.5 | Stephanie Desmond talks to Dr. Demetri Sianopoulos, a resuscitation expert at the University of Minnesota, about efforts to improve outcomes by using a method that gives doctors more time to |
| 0:56.5 | save their patients. Let's listen. Dmitriianopoulos, thanks so much for joining me. |
| 1:03.2 | Thank you so much for having me. It's a pleasure to be here. |
| 1:06.6 | So I have read with fascination about your work using a different form of CPR and testing it. |
| 1:14.7 | And I'd like to start sort of with just a reminder to people what CPR is, what it's for, and how effective it is. |
| 1:24.1 | Very good. That's a wonderful question. CPR is what we call chiro pulmonary resuscitation and the main |
| 1:32.0 | purpose of the intervention which is actually a medical intervention it can be performed by lay |
| 1:37.7 | person by medics by physicians by nurses is an intervention that takes over the function of the heart and the lungs. |
| 1:46.6 | And effectively, it's what we all see in the movies or in shows where somebody's |
| 1:51.8 | compressing somebody's chest, and that compression on the chest increases the pressure |
| 1:57.4 | inside the chest, like squeezing a toothpaste, and so it pushes the blood |
| 2:02.2 | out towards the brain and the rest of the organs. |
| 2:05.3 | And during the decompression phase allows the chest to fill back up with blood, and basically |
| 2:11.3 | that repetitive the heart pumping. |
| 2:15.2 | Now we also focus on giving oxygen. Circulation is there to give |
| 2:20.0 | oxygen. And by giving ventilations, the respiratory part of the CPR is there to change gases |
