Apparently, her husband was in this afternoon.  He had a box of her pain medications.  It is unclear whether she took a bunch of these or precisely what happened.  I was contacted that she was less responsive.  She periodically has some difficulty to arouse due to pain medications, which she has been requesting repeatedly, though at times does not appear to have objective signs of ongoing pain.  The nurse found her and was unable to arouse her at this point.  There was a concern that she had taken some medications from home.  She was given Narcan and appeared to come around some.  Breathing remained somewhat labored and she had some diffuse scattered rhonchi, which certainly changed from this a.m.  Additional Narcan was given as well as some medications to reverse a possible benzodiazepine toxicity.  With O2 via mask, oxygenation was stable at 90% to 95% after initial hypoxia was noted.  A chest x-ray was obtained at this time.  An ECG was obtained, which shows a sinus tachycardia, noted to have ischemic abnormalities.
