(ABC 6) – Every day, first responders have to be ready to act on a moment’s notice.

For 23 years, Dan Buelow has been answering the call with the Norwich Township Fire Department. On Saturday, he did it again.

Buelow was in Harrisburg, Pennsylvania, with his son for a volleyball tournament when his attention shifted to a coach.

“I saw he was going down. I didn’t think anything except to get over there and help.”

The first thing the off-duty firefighter did was try to find out the man’s medical history. Then, he performed a sternal rub to test consciousness.

“We rub really hard on the chest. Sometimes it’s very uncomfortable and so people will go ‘ah.’ They’ll moan. They’ll yell at you.”

When the man stopped breathing, Buelow went to the next step.

“I went ahead and found my landmarks and I just started CPR.”

Unfamiliar with the environment, the veteran firefighter and EMT looked for an automated external defibrillator or AED, found it, and wasted no time putting it to use.
