"It's really gutting to see. When you rock up [to a hospital] and then there are five, six, seven ambulances outside, knowing that we're going to be waiting for hours with that patient." These are the words of Welsh Ambulance Service first responder Will Moore on the pressures the essential service is facing at the moment.
Will, who works for the service in the Cardiff area, is just one of hundreds of paramedics and ambulance workers who help people across the city - and further afield when needed - every single day. They each have families, lives outside of their careers, yet every day are faced with the extreme pressures of the job.
In Will's case, as a rapid response paramedic, he is often the first on the scene of some of the most acute and serious calls the service receives. He spends the first crucial minutes assessing patients, reassuring family members, managing the scene, holding down the fort until backup arrives.
