This episode explores how life can change in the blink of an eye and how life or death depends on the actions of those around you when things go wrong. Leanne is the sister in charge of Resus today. Kevin, who's 78, is rushed to A&E by ambulance a... (more)fter suffering a cardiac arrest while exercising at the gym. Luckily for Kevin, gym instructor Jeff was nearby and was trained to use the gym's portable defibrillator to save his life. Kevin's wife Maureen was next door in the gym's swimming pool while all this was going on and came out of the changing rooms to find out that her husband's heart had stopped for a minute. Kevin begins to stabilise and he's sent to the specialist cardiac catheter lab for an emergency procedure. Meanwhile, 23-year-old paramedic Declan has been brought into A&E by his colleague Amy. He's feeling dizzy and junior doctor Sammy is concerned that there are signs he may have a problem with his brain so she sends him for an emergency CT scan to find out what's happening. And 83-year-old Monica has been rushed to King's after falling at home. Monica suffers from osteoporosis and is complaining of numbness in her leg after the fall. Her initial x-ray appears to indicate that she's suffered a broken neck. As she's treated, Monica talks about scrumping apples as a child, missing out on being a mother and losing her husband in a tragic accident.
