Yeah, that was the sense I was getting about IVC compression with sonography, but my eyes were a little opened when I read the last comment of the blog post above: ICU Physiology in 1000 Words: In Defense of the Central Venous Pressure - PulmCCM the commenter says that IVC compression is not much better than CVP?? that's not what the attendings in our unit do?

Thanks, I thought it was a nice, quick description of the physiology of the CVP. I hope others find it useful too.

Increasing levophed does increase the CVP, it does so by increasing the mean systemic filling pressure which increases venous return to the right heart. see this post for a review http://pulmccm.org/main/2014/review-articles/icu-physiology-1000-words-defense-central-venous-pressure/
