Pupils at St Helena School learn what could be their most important lesson yet - how to save a life.

Year 11 prefects at St Helena School spent their afternoon getting hands on CPR lessons with Kathryne Burke, a nurse from the University of Essex.

This is part of World Restart a Heart day, a partnership between the Resuscitation Council, British Heart Foundation, British Red Cross, St John Ambulance and every ambulance service in the UK.

This is the fifth year the scheme dedicated to educating and raising awareness of how to help someone who is suffering a cardiac arrest has been running.

Claire Wild, health and welfare officer at St Helena School, has been supporting the initiative to teach pupils CPR.

Some of the pupils, like Jurij Sevcenko, who took part in Tuesdays class had done CPR lessons before.

He said: "I've done it once in year 6, but it's good to recap, just in case really. It's a good skill to have and to remember."

Emma Pugh, who had never learned CPR before, said: "If you're in a situation you would be more confident.

"I want to go into the medical profession so it's very useful and like Miss said, it'll make us stand out."

Kathryne Burke, said: "They were excellent, and had a very mature attitude. They all gave it a go. They were fearless actually.

"They are all perfectly capable of delivering good chest compressions. They really went for it."

After learning the key elements involved in CPR, further classes throughout the school are being rolled out and lessons on child CPR, how to use a defibrillator and the recovery position are next on the list.
