Dr. Mehmet Oz aided a man who called out for a doctor and then collapsed at a Pennsylvania Republican event this weekend. 

"I'm a doctor, it's my calling, I'll always be a doctor, and whether I go into politics or any other profession, I'll always be a physician," said Oz, according to Fox 56.

Oz, who is running as a Republican for Senate in Pennsylvania, was slated to deliver a speech at the Pennsylvania Republican Caucus meeting Saturday morning near Pittsburgh when an unidentified committee member with the caucus called for a doctor and reportedly had a seizure and lost consciousness.

Oz, a cardiothoracic surgeon, was able to stabilize the man until emergency medical personnel arrived on the scene. 

"I started practicing the ABCs, and it's a bit of a teachable moment. So, the first thing you do is check the airway, that's the A. Are they breathing, that's the B, and then C is their circulation, is their blood flowing," Oz said, Fox 56 reported.

"Once he got to the emergency room, he got stabilized. He says he's doing okay, and I'll keep checking up on him," said Oz. "I'm optimistic that we'll find out what's happening and be able to address it expeditiously," said Oz.
