Thanks so much. And yes, things just don't add up and we did have him moved to the most reputable hospital in the area since we didn't feel he was receiving the best care. We have spoken to the doctors and they don't have answers either. We think it was a combination of things, he was receiving 2 different meds for his blood pressure/heart rate plus the sedation for the pacemaker, then the fentanyl. This started as a mitro valve prolapse repair which lead to the pacemaker. Ultimately led to this unresponsive state plus his liver and kidneys are a concern as a result of this as well. Regardless, he is currently responding and following commands (squeeze my hand etc) and they are going to try and remove the ventilator later today. We just hope most of this is reversible.
