Some quick thinking co-workers are being credited with saving a man's life in DC.

It happened earlier this month in an office building in Dupont Circle.

According to DC's Fire and EMS Chief, Gregory Dean, a man went into cardiac arrest during a business meeting at FHI 360.

One of the man's colleagues, Danette Purvis, then decided to conduct CPR.

Purvis, and 20 other people, including emergency crews and a security guard, ultimately played a role in saving the man's life.

Purvis had only learned CPR one day before the incident.

"I just straightened his body out and I started chest compressions immediately," she said.

The man who went into cardiac arrest is Kenneth Miles. He is currently recovering at George Washington Hospital.

Mayor Muriel Bowser joined Chief Dean to thank the group for its actions Wednesday morning.
