question: My mom aspirated & had to be recessitated. Docs said she was out for 8-15 minutes. (2 different docs each say different times) She has 2 CT scans done and they eacChatDoctore back negative for any bleeding, swelling or a stroke. She s been on a vent for 6 days now. All vital signs are normal. BP is normal. Doctors say she s using the vent at minimal settings. But she is not showing signs of improvement such as foowing basic commands. She has been diagnosed with encepalopathy. What are the chances she will wake up from this?
