A man who credits three Mount Royal University students with saving his life has made a donation he hopes could save the lives of others like him.

After a game of squash at the university's courts this month, Ayaz Kara suffered a heart attack. Three students trained in first aid administered CPR and then used an automated external defibrillator (AED) to restart his heart. In appreciation, Kara has donated five more of the devices to the university in the hopes they might help others like him.

"I'm really going to endeavour to do some fundraising and stuff like that to be able to get some other AEDs for other places that really need them," Kara said. "I think what happened to me, and a lot of people can be saved if they get the right treatment at the right time."

AEDs work by delivering an electrical shock to victims of cardiac emergencies in order to restart their heart.

The devices contain sensors which can track the heart's activity and advise the person using it whether a shock is required.

Roughly 40,000 cardiac arrests happen every year in Canada.

According to the Heart and Stroke Foundation, the use of an AED with CPR can increase the likelihood of surviving cardiac arrests by 75 per cent or more.
