A team of 60 health professionals is preparing for Saturday's U2 concert that could draw 100,000 to the outdoor venue at Magnetic Hill in Moncton.

Moncton has hosted a series of high-profile outdoor concerts starting with the Rolling Stones concert in 2005.

Dr. Gary Duguay, who is leading the concert's medical team, said he is looking forward to the event and working with the large group of health professionals.

He said an event that could see 100,000 pack into the outdoor venue attracts a certain type of medical volunteer.

"Knowing most of the volunteers, they're kind of adrenaline junkies — the kind of people who enjoy their work in the emergency room so they enjoy just as much to see all the chaos and the action behind the scenes," he said.

Duguay said he won't see much of the show, but he'll make sure his volunteers get a break now and then to take in the performances, such as U2 and Arcade Fire.

Duguay said the medical team is ready for anything that could happen during the event.

The Moncton doctor was involved with the inaugural mega concert at Magnetic Hill back in 2005. At the time, the medical professionals did not know what to expect.

Other than a few cases of heatstroke and dehydration, Duguay said the first outdoor mega-concert went smoothly.

Then came the Country Rocks the Hill concert in 2007, when torrential rain flooded the grounds and the medical tent.

The doctor said chaos erupted just as the concert was ending.

"Two paramedics came running down from one of the satellite tents with a patient who was having a cardiac arrest," Duguay said.

Duguay said they had to perform CPR and use a defibrillator, with water pouring on them and rising below them.

The patient survived and Duguay said it was the most remarkable case of his career.
