Just came across this review and figured I should share. The authors make a great synopsis and review of POCUS in acute illness:

MOPOCUS Review by Ha &To

The only thing I would add to this is a more physiological way to assess the IVC, which I’ve blogged about here.  Sadly, I’ve heard a few people stating how they didn’t want to get into the dogma of IVC ultrasound, that it wasn’t reliable, etc.  The IVC doesn’t lie. It’s just not a recipe. The IVC findings have to be integrated into the rest of the echo graphic and clinical examination.  Trying to use it as a single value is akin to using serum Na+ as a diagnostic test for volume. It works only sometimes.

Please spread among the POCUS non-believers. We’ll convert them, slowly but surely. But the sooner, the better for the patients. Again, there’s no excuse to practice acute care without ultrasound. It’s not right. I’m not saying every probe-toting MD is better than one without, but everyone would up their game by adding POCUS, once past the learning curve!

cheers!
