Cardiac Nurses....have you ever....

Published

OK I typed up this huge whole scenario with background and everything and it didn't post....the computer locked up so I'm not going to retype the whole thing but here's my question.

Have you ever given Lopressor (25mg) to a pt with a HR of 130's and SBP of 60-70 (assymptomatic pt) in an effort to lower the HR?

Yes, I've given metoprolol IV with a low systolic and high HR. Their BP may be low R/T the low CO from the high HR.

In one specific instance, I gave cardizem a few times, then adenosine twice, then finally metoprolol 5mg IV, and it wasn't until the metoprolol that the HR went down and the BP came up.

MAP is a simple mathematical calculation. You do not need invasive monitoring to determine MAP, simply the BP.

AH I did not know that. I'll have to look it up. I've been told that under SBP of 80ish that's the relative cut off for good organ perfusion. It's nice to know there's a way to calculate it. That's why I was a little surprised that at SBP of 60 this pt was alert oriented and talking on the phone sitting up in a chair.

This is such a good place for info / experience. Thanks
