I underwent surgery to repair a foot fracture. The surgery had no complications and I was sent to recovery with normal vital signs. I was given the upper limits of normal amounts of pain medication in recovery and then discharged to the floor after a short time. I was placed in my room where the nurse did receive report on me, which included the diagnosis of sleep apnea and obesity. The nurse did not put any monitroing equipment on me, including no pulse ox. I was not looked upon for the next 55 minutes. I was found 55 minutes later with a Oxygen level of 66%, bluish in color and not responsive. A code was called and I was given Narcan to arouse me. My question is what effects did this prolonged decreased oxygen level have on my body, (brain, organs etc)?
