Updated:DUNWOODY, Ga. —
An off-duty Dunwoody police officer was in the right place at the right time when a man collapsed in an office building this week.
On Thursday, the officer and a heroic businessman walked Channel 2’s John Bachman through the rescue, and the officer revealed a little lifesaving box that's as standard issue as his gun.
Dunwoody police officer Chris Irwin had just completed his 12-hour shift Monday night and was on his way home when he heard a medical call at a nearby office building. He turned around and raced up to the 10th floor. He said a group of people were waving him down.
"It was intense. It really was a lot of commotion," Irwin told Bachman.
Mark Vosk was in a meeting at National Financial Services group with several people when one of the men went quiet.
"I hit him in the chest and said, ‘Bob?’ Nothing. His head rolled back and eyes started to roll back in his head," Vosk said.
Vosk and others started CPR and called 911. Irwin was closest, so he grabbed his portable defibrillator and got to work.
Today at 4, Irwin demonstrates the skills he used to help revive the patient.
