So given the importance of these topics, the number of questions and discussions we’ve had on the twitterverse, and most importantly in the spirit of #FOAMed, here is the chapter from the POCUS book which was co-authored by Rory Spiegel (@EMnerd), Korbin Haycock (@korbinhaycockmd) and myself.
We’re also in there introducing our VEXUS score, and if anyone wants to use/validate it clinically, please do!
Love to hear anyone’s thoughts!
PS we’ll all be at H&R2019 and running workshops on venous congestion:
The rest of the chapters are here on Amazon and the e-version here on iTunes!
cheers

thinking critical care 
Thanks Philippe for this excellent work.
I am just curious if it is possible for a collapsible IVC and PW findings suggestive of venous congestion to coexist, say, for example, if the congestion actually leads to increased IAP (perhaps not to the extent of intra-abdominal hypertension) or even 3rd spacing to form ascites in a leaky patient.
My 2nd question is: does the physiological changes by pronation (e.g. variable change in transpulmonary pressure, slight “off loading” of the abdomen etc.) cause an observable change to the spectral findings? I often have this question in mind when I want to assess fluid status in a prone patient on whom doing an echo isn’t always possible.
Thanks and I look forward to the amazon stock becoming available.
