I am a neonatal nurse practitioner and we deal with asphyxia frequently unfortunately.
What they posted is very grim, sadly

Chase may need a tracheostomy if he cannot keep his own airway protected from secretions and his autonomic dysfunction will make him prone to stroke, which will only damage things more. The only "bright side" (which is a very dismal side indeed) is that likely the personality and sentience that was the little boy has likely gone. Hopefully he will not have enough consciousness to be uncomfortable from contractures and other issues.
This is the hardest to see in patients.....their personality/soul/essence/etc has left the building, but their brain stem is intact. Parents are left caring for a shell that will keep on for a long time
I so wish his family didn't have to go through this.
