Ottawa now has its first ever outdoor defibrillator. It's located at St. Luke's Park off Elgin Street in a weather-resistant, heated case so it can be used all year round.

The automated external defibrillator (AED) can help save someone's life in the case of a sudden cardiac arrest. The machine has step by step directions on it for those with no CPR training as well as vocal commands. Cardiac arrest survivor Katrysha Gellis says the most important step in responding to a medical situation is acting quickly.

"I actually suffered a cardiac arrest just after my 30th birthday. My heart stopped beating suddenly and I collapsed. Because I was with two colleagues at work who recognized I arrested and what to do, they were able to call 9-1-1 and get first responders on the way then they started doing chest units," she said.

"There was no defibrillator on site unfortunately, so my story could have had a different ending." Gellis says her situation was a stroke of luck. Firefighters were around the corner and within two-minutes, had a defibrillator on site.

She says not everyone has the same fortune and it's important to have AEDs accessible 24/7. "Cardiac arrest happens; every second matters. Within four minutes, brain damage is going to start to set in and if nothing is done after 10 minutes, brain damage is irreversible," Gellis said.
