Staff from seven secondary schools were taught life-saving skills at Calderdale Royal Hospital.
They were invited to the training so that they could deliver basic life support training to school children across the district.
Calderdale and Huddersfield NHS Foundation Trust provided the training, donated a manikin to each school and has purchased manikins for other schools to use.
The session was led by accident and emergency consultant Dr Andy Lockey. He said: “We would like every secondary school child in the Calderdale area to be taught basic life support at caldeskills. Evidence shows that this will lead to many lives being saved in the future by equipping each child with lifelong skills. As an organisation, we see this as a great example of helping the local community to prevent serious health issues.”
More schools will attend another session in the summer.
