Know CPR, have AED handy - it works.

RICHMOND – A 57-year-old grandfather watching his granddaughter play in a high school basketball game collapsed in the stands Tuesday night, and authorities are crediting the skillful, quick use of an AED in reviving him.

Richmond-Burton High School athletic trainer Julianne Stewart administered a shock to the Poplar Grove man with an automated external defibrillator – one of four the school has on premises. He had suffered a heart attack and collapsed face forward about 7:15 p.m., just before half time, school and emergency officials said.

“Julianne Stewart had the wherewithal to get the AED and ... she delivered a shock to revive the gentleman,” Richmond Township Fire Protection District Chief Rick Gallas said. “By the time we got there, he was breathing and starting to talk.”

A Richmond emergency crew took the man, whose name was not released, to Centegra Hospital – McHenry.

Gallas also credited Dave Ernst, a father who was in the stands for his daughter’s basketball game, for performing CPR on the man before Stewart came over with the defibrillator.

“Dave determined that [the man] was not breathing; he was turning purple, and did CPR on him,” he said.

Richmond-Burton Principal Tom DuBois said the incident was a bit frightening, but that everyone involved responded appropriately and everyone was happy about the positive outcome.

“His son and daughter-in-law just stopped by to thank us,” DuBois said Wednesday morning. “They were on their way to the hospital to go see him. … He appears to be doing OK.”

Gallas said the quick response should greatly benefit the man’s recovery.

“It just goes to show the value of CPR and the use of an AED in the field,” said Gallas, who added that the fire department will present both Ernst and Stewart with a life safety award.

Ernst and Stewart were unavailable to comment Wednesday.
