Alyssa Milano's uncle Mitchell J. Carp, who was involved in a car accident last week, is still on life support.

In a video she shared on TikTok on Monday, the "Charmed" actress said her uncle is "still in and out of consciousness" as she expressed hope that her beloved relative will survive the ordeal, People reported.

"He is on life support," she said in the TikTok video. "My brother went there yesterday and played him some 'oldies' and his whole body started moving, so he really loved that."

"The nurses at the UCLA Medical Center and the doctors are taking such incredible care of Uncle Mitch, but he's got a long road ahead of him. He spiked a fever last night of 103, so we think that there is an infection that he is also beating throughout all of this. But he is a fighter, Uncle Mitch is a fighter, and the doctors say that every day is a miracle that he still hangs on," she said.

"So, thank you again, for your concern, for wanting to know how he is. Please, please, please get trained in CPR. You could be called upon to save a life at some point, and it's really, really valuable to know how to do that," Milano continued.

Last week, Milano's uncle suddenly became unconscious while driving on a Los Angeles freeway. The actress was sitting in the passenger seat.

Mitch "started to have an unknown medical issue" while driving last week. His Ford SUV then drifted to another lane and hit a vehicle, according to a press statement obtained by ET at the time. Milano later confirmed that her uncle Mitch suffered a "serious heart attack" while driving.

Milano described the car crash as "horrifying" although it was her presence of mind that saved them both. She used her hand to hit the brakes. Later, a "good Samaritan" helped them bring the Ford to a halt. The actress performed CPR on her uncle until medical assistance arrived.

"It was some of the most horrifying moments of my life," Milano said in the TikTok post.
