Joining Brian and myself in our virtual studio is Dr Erica Tinson one of our fabulous lecturers in Emergency and Critical Care here at the RVC. Erica has an interest in a variety of topics though we thought that we would discuss the highs and lows of sodium. We focus on the management of the extremes of both, hopefully not something you see commonly, but we hope will help when you do. We hope that you enjoy.

Normal Na+ is the patients normal sodium concentration.
