Cleveland Clinic - the #1 cardio-vascular clinic in the world - is better.
CC website states that victims of cardiac arrest lose consciousness almost immediately.
Unconscious persons with no pulse and no blood pressure do not have to be restrained from thrashing about.
And, I have never heard of treating post-cardiac arrest victims with deep sleep sedation and intubation.
And, the fact that the family and the NFL have released ZERO detailed information for 36 hours simply pours gasoline on the speculative fire.
“Seizure-like activity, including abnormal/tonic movements of the body, extremities, and face and eyeball deviation, is a major sign/symptom of the “sudden” onset cardiac arrest, particularly ventricular fibrillation and tachycardia.”

Also, this young man is/was not breathing on his own, he is intubated (ie. on life support) and apparently they have been able to reduce his oxygen intake from 100% down to 50% due to some improvement. It is very possible that the CPR performed on the field caused some lung injuries or perhaps a broken rib or punctured lung. His Uncle says he has lung injury. So therefore he was/is intubated. I also ad that basically the young man died twice, once on field and once in hospital and had to be revived. So being in ICU and intubated with lung injury is not at all far fetched.
