The waiting room in Barnsley Casualty is overflowing today: Resus is crowded and there are no spare beds in the hospital. Sister Jane, who's running the hub, will have to juggle patients to make room for new emergencies.

Fifty-two-year-old warehouse worker Wojcieches is rushed in by ambulance after suffering an epileptic seizure at work. In Resus, staff nurse Amy takes charge of his care, but Wojcieches drifts in and out of consciousness. Too little recovery time between seizures could lead to permanent brain damage.

Dr Chris Yeoman is urgently called over to Resus where 64-year-old Lynn has severe abdominal pains that he suspects are caused by a ruptured appendix. If confirmed, Lynn will need an emergency appendectomy.

In Paediatrics, Junior Doctor Josh Gemmill faces a different sort of challenge. Fifteen-year-old Thomas has a ring stuck on his injured finger that's threatening to cut off his blood supply. When the hospital cutting equipment isn't strong enough to remove the ring, Dr Gemmill has no choice but to call in the Fire Brigade.

And staff nurse Mimi plays a vital role today in reducing queues in the waiting room. She runs Triage caring for patients like 22-year-old Elliot who was attacked by a street gang just hours after being involved in a car accident.
