When the call went up, ‘is there a doctor on board?’ a celebrity GP in the US put his hand up — and ended up saving a passenger’s life, mid-flight.

Dr Mikhail Varshavski, a primary care physician from New York City, who’s better known as Doctor Mike, was on a Delta flight when the medical emergency occurred.

Twenty-six-year-old Matt Faraco from Atlanta, Georgia, started to go into anaphylactic shock two hours into the flight between New York and Tel Aviv, according to a report on Fox News.

“I was on the plane and I actually hadn’t eaten anything, but I noticed my hands were swelling. I told the stewardess I was feeling unwell,” Mr Faraco told Fox News.
