EMS LHP EP67 - DOSED-VF

The EMS Lighthouse Project

If one is good, two must be better, right? If it applies to cookies and ice cream, why not defibrillators? That’s the question the DOSED-VF trial set out to answer. We’ve covered this topic in episodes 12 and 27, including going over the pilot trial of DOSED-VF. But now the full meal deal is available. And you may have heard it was stopped early because… well, you’d best listen to find out.

As a special bonus, Dr. Jarvis explains the difference between odds and risk after falling into the statistical rabbit hole. Remember, this podcast also has a YouTube version complete with graphs and charts (oh, my!): https://www.youtube.com/@FlightbridgeedHEMS/playlists
