Been gone nearly 2 years and back in the ICU. Need a little refresher but hosp. is not a teaching hospital. When doing bloods, I've been 'pushed' into doing VBGs from small, peripheral lines. This makes no sense to me. Even if, as some of my colleagues are stating, we're doing it to follow a trend, we're only trending the perfusion to that arm, no? I don't see the point?
Also, how reliable is a CVP reading from a PICC?
Many thanks for the input!
