BP cuff or A line

I always check for corelation, if the values are significantly different then I take cuff pressures on other extremities. If my a-line is different then all of these, then I trust cuff. The reason why I check different cuff pressures is because it is fairly common for pts to have left subclavian stenosis that will give you a false low SBP. You can also try a "rose" on your aline if there is a "whip" in the reading. Sometimes that will help.

Hey fellow NICU nurses. I have a quick question for all of you gals and guys. Whenever a patient comes back from OR with a perfectly working A-Line do follow for of the A-line or a BP cuff? We follow the BP cuff I think A line there is less room for error (of course unless wave is dampened) and get a more accurate reading. Tell me what your ICU uses for recording BPs?
