ABG VALUES - siren

Posted: Nov 11, 2009

Is the base excess in ABG values always a negative? I have only heard things such as base excess -2.9. However, this doctor is stating just base excess of 2.9.

Base excess - MT17

Normal base excess values are -5 to +3, if that helps any?

base excess positive/base deficit negative sm - flybye

The words "base deficit" and "base excess" are equivalent and are generally used interchangeably. The only difference is that base deficit is expressed as a negative number and base excess is expressed as a positive number.

So in your case, base excess, it would be a positive or 2.9.

USUALLY the docs don't mix it up, but i've heard them say "negative base excess" before...

keeps us on our toes...

Do some of these lab values seem impossibly high, particularly the AST and ALT? He clearly states these values. Her Chem-7 from yesterday revealed sodium 134, potassium 7.8, chloride 92, bicarbonate 25, sugar 293, BUN 120, creatinine 7.2, calcium 8.8, AST 2898, ALT 3595, ammonia 97, total bilirubin 2.3. ...

Ok. I have a question about how to properly transcribe PSA values. In every previous job I have had transcribing urology notes, I was told that if they give you a single number like 1,2,3..to transcribe it as 1.0, 2.0, 3.0, etc. I would get in trouble if I left off the .0 after the number. I also think this looks better on paper. However, my editor on this account (who I think is very old-school) says to leave the .0 off. What do you guys think? I already had ...

I am preparing for the RMT exam. How much detail of the normal lab values do I need to know? Do I have to memorize all the normal values at the least? I find that impossible. Do I have to know what test will diagnose for which disease or particular study? For example, do I have to know that white blood cells are involved in the CBC test or that PSA stands for prostrate specific antigen and is a cancer marker? How much information about the drugs do I need to know? What kind of lab valu ...

Sorry, my math really sucks and I can't seem to find a site that will 'convert' decimals to regular numbers. If a patient's lab test reads as 23.0 and the doctor dictates it as 23,000 are these both correct ways of putting it? Also had absolute segment coung of 17.48 that was dictated as 17, 480 and bands of 0.23 that were dictated as 230. If these are just other ways of expressing the same number and are all correct, great- I just want to be sure that is the case. I ...
