Damar Hamlin remains in the ICU, Here's what we know about the Buffalo Bills player's condition
Damar Hamlin spent Monday night in an intensive care unit and remained there Tuesday in critical condition, the Buffalo Bills said in a statement.
The 24-year-old NFL player collapsed during a game against the Cincinnati Bengals on Monday night, and Bills officials said he suffered a cardiac arrest.
Hamlin's uncle, Dorrian Glenn, spoke to reporters outside the University of Cincinnati Medical Center on Tuesday night and said his nephew's heart stopped twice, once on the field and again at the hospital, CBS Chicago's Charlie De Mar reported. He also said Hamlin has lung damage and can't breathe on his own. The player had been receiving 100% oxygen from a ventilator but that is down to only 50%, he said.
What happened in the Monday Night Football game?
With 5:58 to go in the game's first quarter, Bengals wide receiver Tee Higgins, who was running the ball, hit Hamlin, a 24-year-old safety, in the chest with his helmet during a play. Hamlin dragged Higgins down to the ground. Hamlin stood up right after — but a few seconds later, collapsed.
Medical personnel attended to Hamlin for 19 minutes on the field, The Associated Press reported, and Hamlin received both CPR and required an automated external defibrillator. CBS Sports reported he was placed on a stretcher, then put in an ambulance, where he was given oxygen, to be taken to the hospital.
The remainder of the game between the Buffalo Bills and Cincinnati Bengals was postponed.
The Bills said early Tuesday that Hamlin had suffered cardiac arrest and his heartbeat was restored on the field, and he was transferred to the University of Cincinnati Medical Center for further testing and treatment. He was sedated and listed in critical condition, the team said.
Fans rallied outside the hospital overnight and donated millions of dollars to Hamlin's effort to buy Christmas toys for children from his hometown of McKees Rocks, Pennsylvania, outside Pittsburgh.
What is "commotio cordis"?
While it's not yet clear exactly what Hamlin experienced, CBS News medical contributor Dr. David Agus said Hamlin may have suffered what's known as commotio cordis, which is heart arrhythmia that occurs when someone takes a direct hit to their chest.
Agus said approximately 30 cases of commotio cordis occur in the U.S. every year, including among Little League players who get hit in the chest with a ball.
Describing the condition as "a confusion of the heart," where the heart muscle pumps erratically, Agus said the energy of the blow interferes with the electrical signals in the heart, creating a new beat known as ventricular fibrillation — a fast, erratic heartbeat that does not pump blood into the brain. When that happens, Agus said the heart needs to be shocked back into regular rhythm.
"That's why there are defibrillators on the sidelines of games, is to be able to use them to shock the best heart back into a regular rhythm," he said.
Agus said every minute blood flow is stopped to the brain increases the potential of severe consequences — including death.
"Every minute you wait is basically 10% increase likelihood of death — so the quicker you do it, the better," he said.
There is a question of whether Hamlin suffered any injury to his brain from his heart stopping. The faster they were able to get his heart started, Agus said, the more likely it is he will recover quickly.
"People who don't even know us are showing love and support and we're so thankful for that," Glenn, the player's uncle, said. "I know those prayers are helping because he's definitely recovering. ... God got a mission for him and that's why he's still here."
