Led by the IRFU's Player Welfare Co-Ordinator, Shane Mooney, the SAFE (Standard Approach to Field Emergencies) Rugby course was designed to show step-by step processes of attending to somebody who has collapsed and is in need of assistance.
Players and staff were shown examples of situations, both on the field and off, where somebody may experience sudden cardiac issues.
With IRFU staff on hand to assist, the players practised clearing airways, chest compressions and breathing air into dolls, with the aim to replicate a real life- scenario.
Ulster Rugby's Medical Director, Dr Michael Webb, says that the course provided a vital reminder of the importance of knowing what to do in a medical emergency, whether it be for a fellow player or member of the public.
"It's really exciting that we have been able to get so many players and staff together to learn a really important life skill. You never know when you will be confronted by a person who has collapsed or suffered an emergency, to know how to save a life is a wonderful skill to have.
"There have been a number of high profile cases within sport recently and also with spectators, you never know what you will encounter when you have big crowds at a stadium. To have people on-hand to deliver effective CPR and use an AED will save lives."
Dr Webb was encouraged by the involvement of the Senior Men's team, who were eager to learn and practise the skills.
"We floated idea this by the players and they have been really enthusiastic about taking part, they have driven it, came in on their day off to do the training and I hope have taken a lot out of it."
Ulster player, Alan O'Connor, said he found the course very valuable adding; "It's a life skill, if someone is in need, it really helps if you know the basics of what to do.
"If somebody needs help and I'm around hopefully now I can help them. Knowing the basics of CPR and how to manage the situation around a sudden cardiac arrest could save someone's life."
