Licensed practical nurse Donna Davis sprang into action March 8 when she encountered an unresponsive man in the parking lot of a Walgreens store in Milwaukee, reports CBS affiliate WTVR.
'"He had no color, no pulse, nothing," she told the station. "He didn't look like he was breathing."
A woman who was with the unconscious man said he had taken heroin. Ms. Davis, who is studying to become a registered nurse, yelled for someone to grab Narcan from the Walgreens pharmacy.
The man regained consciousness after receiving the opioid overdose antidote, along with CPR from Ms. Davis.
"At the end of the day, I was only trying to do the right thing — and I would do it again for anybody," she told WTVR.
