The Resus Tracks 05: Kenny (@heart_lung) Tackles Shock Perfusion! #FOAMed, #FOAMcc, #FOAMus

So finally got around to corralling Physiology Jedi Master Jon-Emile Kenny for a chat, which is always a tremendous learning opportunity. And this time was no different. Jon breaks down some of the mysteries around arteriolo-capillary coupling and shock flow, and brings up some really interesting potential uses of the critical collapse pressure of small arterioles, and hints at how we may be able to use some POCUS techniques to clinically assess tissue perfusion.

Here you go:

The Resus Tracks 03 – Shock Circulation with @EMnerd! #FOAMed, #FOAMcc, #FOAMer

Here we go!


Discussing with Rory is always awesome, because he manages to distill things to the most important stuff. In this one he basically says sure Phil, it’s fun to think up all kinds of semi-theoretico-imaginary hemodynamic stuff, but you gotta make sure you control the source!



Love to hear comments and criticisms!




Here is the open access paper I was talking about, graph on page 2.

H&R2019. A bit Bigger. A LOT Better! #HR2019

First of all thanks to all of last April’s participants and faculty who made this an awesome event. For those of you who missed the inaugural event, no worries, this edition will be even better. Building on the feedback, we’re cooking up a really nice little program that will keep H&R small, packed with clinically useful talks and both cutting and bleeding edge lectures (don’t expect guideline rehash!), and even more faculty interaction.

We will have some parallel tracks to make sure the ED people get some more ER-specific stuff, that the CC people get some esoteric tweaks about obscure ICU topics, and the hospitalists and pick and choose.

We’ve added a pre-conference course day packed with great stuff. The real problem will be choosing:

Felipe Teran (@FTeranMD) brings us a full day, resuscitative TEE workshop including basic certification – first time in Canada!

For educators and anyone wanting to up their presentation game, my good friend Haney Mallemat (@CriticalCareNow) brings his unique Keynotable workshop. If you’ve ever heard Haney talk, you know he is the leader of the pack when it comes to delivery, so not-to-miss opportunity to learn form the master.

Hospitalist POCUS? Check. Hospitalist procedures? Check. Percutaneous tracheostomy and emergency surgical airway? Check. Advanced POCUS like renovascular and transcranial doppler? Check. And a lot more…

Basic info:

May 22nd – pre-conference courses

May 23rd – The Hospitalist

May 24th – The Resuscitationist

Preliminary programme available October 1st here.


So mark your calendars. Bring the fam, check out Montreal, and pack in a bunch of solid, ready-to-use clinical knowledge but also some paradigm-shifting approaches and viewpoints!








Resuscitation Tracks 02: Hemodynamics w/@iceman_ex #FOAMed, #FOAMcc

So I’m in the process of putting together my resus handbook, and the really good thing about writing something up is that it forces one to beef up the entire mental database and fill in blanks that may sometimes be filled by belief, habit, culture or leaps of faith. So part of my process will involve discussing stuff with the brightest guys I know. Who happen to be pretty bright. So I figured it might be stuff worth sharing!

Here, Segun and I discuss the possible uses of Pmsa, of resuscitation philosophy, and touch on the issue of blood pressure vs perfusion. (please skip to 0:30 – sorry can’t cut out!)


Love to hear some additions to our discussion!

Here is the paper I was referring to, with the graph on page 2:

Working out the Clinical Kinks in Venous Congestion: A Discussion w/Rory & Korbin. #FOAMed, #FOAMcc, #FOAMus

It’s really exciting to be at the outer frontier, trying to figure out some new clinical areas. Now these have all been described, however the ability of clinicians to properly identify certain pathophysiological findings has been limited prior to POCUS. Following the trail being blazed by Dr. Andre Denault, we are also working on expanding the applications, particularly in resuscitation/deresuscitation and CHF/AKI. There are more questions than answers, but that’s exactly why it’s interesting.

So for those unfamiliar with the topic here is a small intro:

And for those following, here is the discussion:


Do expect more from us about this. Watch this space. It is practice changing.

The Right Stuff: A New Series on Nutrition. #FOAMed

So here is a little video intro to a new series of posts and discussions I’ll be putting up on the blog in the next weeks and months. And yes, it will tie in to acutely ill patients too…



So please do leave comments and invite yourself into this discussion.

Remember, you are what you eat. It’s true.





H&R2018 Keynote Lecture: Re-Defining Sepsis by Lawrence Lynn. #FOAMed, #FOAMcc

Lawrence’s work on sepsis analysis is truly groundbreaking. To put this in perspective, one has to recognize that sepsis is an exceedingly heterogeneous disease that, once upon a time, and for good reasons, an arbitrary definition was formulated. This, however, does not reflect sepsis adequately, and needs to change with observational data, as this has tremendous implications in therapeutics research.

Lawrence’s efforts have resulted in data systems revealing a number of different patterns of sepsis, with clear differences in physiologic effects or responses. This may explain why so many failed therapies for sepsis have occurred. It is entirely plausible that some of these therapies may have effects in some of these phenotypes of sepsis but get lost in the statistical mix.

Love to answer any questions anyone may have, and Lawrence will certainly chime in on the discussion!
