light anesthesia
"I tried to tell the  anesthesiologist that I have sleep spends, use oxygen @ nite, have 3 included. Major veins and am very sensitive to drugs. He wouldn't listen.  Put me immediately out and my oxygen blood level went down to 51. Had I stayed at that level for 5 minutes I would have died.  The hospital changed the grrecords. I was conguiding. gasping for air. eye Dr said I Jerked side to side violently.  
Lucky it was at a time in procedure that it didn't matter.  Anes searched the sheets/ blankets for the meter and told eye Dr it had come off my finger."
