I got an ER admit today who has COPD exacerbation. The ER nurse reported that she was given 2 g of magnesium IV to help with her oxygenation. I'd never heard of such a thing, and neither had the most senior nurse on my unit. I Googled and found one somewhat sketchy article that says that magnesium can increase oxygen binding to heme: http://drsircus.com/medicine/magnesi...ity-magnesium/
. Does anyone else do this or know if it's true?
