Abordnet

Hi, all!   I used to post here a lot in my student days - been lurking for a few days now.  Don't know what's up with all the cross-posting - SMN didn't have this problem last time I checked in. Anyway, I am in the Army's ICU nursing course and I am trying to clarify some ABG questions.  Does anyone remember that article about interpreting ABG's that involved a square separated into four quadrants?  You made each quadrant stand for something, such as lungs or kidneys and you used arrows to indicate the direction of the disturbance?  If anyone remembers that article, would you please let me know the details so I can track down a copy? Thanks! Terri
