Wow. What a tool. I would first start off by hovering over the physician and doing so until he makes eye contact. I would clear my throat and repeat the bicarb level and pH. To be honest, you have to assert yourself in certain situations. By backing off, you are NOT being the patient's advocate. You might take a little heat, but who cares, someone's life is on the line. Push the BIcarb, get a drip called into the pharmacy, and prepare the electrolyte shifts. ICU_Dude
