Stephanie Carpluk, 19, said her scarf got caught on a spinning scrubber brush while she was working alone Sunday at the Golden Nozzle car wash in Easthampton, Mass., WCVB-TV, Boston, reported Wednesday.
Carpluk lost consciousness as the scarf tightened around her neck and car wash customer John O'Leary jumped from his vehicle inside the wash and cut through the scarf with a pocket knife. O'Leary said he used mouth-to-mouth resuscitation to revive Carpluk.
"I didn't know what to think. I was just scared. I didn't know what the outcome was going to be. I started hearing little things like, 'You're breathing. You're going to be alright. You're back, just stay with me, stay with me,'" Carpluk told WCVB-TV.
Carpluk was taken to the Baystate Medical Center in Springfield, Mass., and was released Tuesday. Doctors expect her to make a full recovery, the television station reported.
