62 year old man was "found down" in his home by a family member earlier this AM.  Per the paramedics bring him into the ER, family members state that he's a diabetic and a chronic alcoholic.  Additionally, he'd been having bouts of fairly severe diarrhea for about 3 days prior to admission.  On presentation to the ER, the gentlemen is nonresponsive and slightly blue.  The paramedics tried to intubate but were unsuccessful, so they have been "bagging" him as best as they could en route.  Labs taken upon entrance to the ER:  ABG:  7.1/49/120/14             135  |   100   |   54   /  265                                                                                                         6   |     14   |  2.4   \     What do you think, by history and by labs and presentation, do you think is happening, at least in reference to his ACID/BASE STATUS;  additionally, you may want to think about what underlying processes may be contributing to his overall condition.
