A school in Hounslow has become the latest to receive a potentially life-saving defibrillator as part of a national campaign.
Staff at St Michael & St Martin Catholic Primary School were shown how to use the equipment to restart the heart of someone who goes into cardiac arrest.
They received training from the London Ambulance Service (LAS) on Wednesday (April 13) using the defibrillator, which was donated by Foran Construction.
The Brentford -based firm provided the automated device, which provides spoken instructions for rescuers, in support of SADS UK's Big Shock campaign.
The national cardiac charity is lobbying to ensure all schools have a defibrillator, which it says boosts survival rates from around 5% when just using CPR to more than 50%.
Foran Construction directors Paul Lavelle and Aidan Thompson said they were told about the charity by Natasha Bradshaw, director of Mortlake Crematorium, where the company has carried out work.
"We both have children and we thought this was a very worthy cause. We're glad to be able to help the school protect its pupils' health," they said.
The school in Belgrave Road, Hounslow, has also been given leaflets showing the warning signs of an underlying cardiac condition to help identify anyone at risk and ensure they receive the necessary treatment.
Headteacher Nicola Duggan said: "It's a fabulous addition to our school to help safeguard the health of our pupils, and we're very grateful to Foran Construction for the donation."
At Christmas, heroic police officers were reunited with a young boy whose life they saved after he went into cardiac arrest at his home in Brentford.
