999: On the Front Line - Season 12

The paramedics plan to take a woman is in the advanced stages of labour to hospital, but when her waters suddenly break, they have to think again. A diabetic man has a painful urine infection, and a 14-month-old is choking and won't feed. A woman collapses at home and needs help getting up, but her daughter is more worried about her increasing confusion.

The paramedics find a man experiencing a life-threatening diabetic hypoglycaemia. It takes the efforts of the fire service to reach the patient, and the only way is up a ladder and through an upstairs window. A woman with dangerously low oxygen levels is struggling to breathe, and sleepwalking may be the reason why an elderly woman has fallen and injured her side.

In Worcester, paramedics are called to reports of a man unconscious in the town centre. A friend says he's been taking drugs, so they quickly get him into the ambulance. A 27-stone man has lost the vision in one eye and has very high blood pressure. Getting him out of the house and into an ambulance requires specialist help and equipment.

When a car collides with two children walking home from school, two ambulances, a doctor and a critical care paramedic are sent to the scene. Paramedics also treat a man who's having back-to-back epileptic seizures, and a four-month-old baby with a barking cough is finding it increasingly difficult to breathe.

Paramedics are called to a rare and unusual stomach condition that's left a patient in agony. On the night shift, a young man is intoxicated and passed out in the street. An elderly man has fallen at home and can't get back up, and a confused and disorientated woman has one of the highest blood pressure readings the paramedics have ever seen.

Paramedics are called out to a woman who got tangled up in her dogs' leads, leaving her lapsing in and out of consciousness on her 45th wedding anniversary. Meanwhile, a man is in severe pain with an umbilical hernia and a woman has a suspected seizure at work. The paramedics also attend a baby that's just been born, with the mother having to deliver her baby on the bathroom floor.

Paramedics help a man with a history of heart attacks experiencing severe chest pain. Treatment at the scene does little to improve his condition, so he is rushed to hospital. Paramedics also treat an elderly man who's collapsed underneath his bed, a baby struggling to breathe, and a 102-year-old woman who may have developed deep vein thrombosis but is reluctant to go to hospital.

A man has been making repeated calls claiming to be having a heart attack. He lives near the hospital and in the past has used an ambulance as a taxi to get him home. Paramedics also treat a woman who is in agony with a slipped disc, a man with a chronic lung disease who can hardly breathe, and a patient who is unresponsive.
