Tune in to the next episode of 999: What’s Your Emergency at 9pm on Monday 3 October on Channel 4.
The last programme in this series explores the challenges that inevitably come with the end of life and how the emergency services have to learn to cope when dealing with death on a daily basis.
In Warrington, paramedics arrive at the home of a man having a suspected cardiac arrest. With CPR already in action and a defibrillator at close hand he is given the best possible chance of survival.
But death is not just a reality for ambulance staff with police officers being called to sudden deaths across the country every day. And some cases prove more complicated than others.
"Before I joined the police, I think I thought to die you had to be old," says PC Sarah Brockley. "I'm not frightened of it, but I hope it's a long time away yet."
999: What's Your Emergency? focuses on the work of police and paramedics in Cheshire. The series follows incidents from the moment the 999 call is made to the arrival of the frontline police and paramedics - the hard-working men and women who protect us from ourselves and each other while seeing us as we really are. They talk with honesty and wit about the ever-increasing challenges of modern Britain.
