Doctors at the University of Cicinnati Medical Center shared a lot of information on Buffalo Bills safety Damar Hamlin's condition.
CNN's Dr. Sanjay Gupta explains what it all means:
- The key message: The doctors have described "a substantial amount of improvement" since it's only been two and a half days since Hamlin collapsed on field during a game on Monday night, Gupta says. "Not only in terms of his overall status, but also ... his neurological status in particular."
- What to consider: "One of the things that you worry about when somebody has cardiac arrest is that there simply wasn't enough oxygenated blood getting to the body, including the brain. And as a result, you don't really know sometimes until someone actually has woken up from sedation and tested the way he was," Gupta explained.
- Positive points in Hamlin's health status: "Being able to communicate. He can't talk — he still has a breathing tube in — but was able to communicate, shake his head, nod his head, things like that. And he's also moving his hands and feet," Gupta noted, adding that's important, "because you worry about spinal cord injuries as well. Those things appear to be doing well. He does not appear to have any deficit there."
- But doctors still describe him as "critically ill": "That's important to remember. I mean it's only been two and a half days. There may be sort of periods of a little bit of roller coaster still in terms of recovery is what you sometimes see with critically ill patients. It may not be a linear track towards improvement," Gupta noted.
