999: On the Front Line

The documentary following the paramedics of West Midlands Ambulance Service returns. On the way back to base, one team is flagged down by police officers dealing with a man who has overdosed on drugs. They are also called out to a woman with gynaecological problems, who is losing a lot of blood and needs to go to hospital, and a man who has a condition where his throat swells up and closes without warning.

Paramedics are called out to a young woman who has had a seizure on a bus. She has epilepsy but the frequency of her seizures has increased dramatically in recent days. The crews also help a man with a lung condition who uses his own source of oxygen, but the canister is in another room and he's too weak to reach it; a young woman with terminal cancer who has collapsed and can't get up; a husband who is worried that if his wife goes into hospital, she won't come out again, but her dementia has reached the stage where a visit to hospital is unavoidable; and a man with low blood oxygen levels who needs the paramedics' help just to breathe.

Police find a man lying unconscious in the street following a suspected drug overdose. When a man is found collapsed outside his house clutching his chest, the paramedics need to act quickly as he may be having a heart attack. A category one call - the highest priority - comes through for a woman collapsed on her bathroom floor and an elderly woman climbs on a chair to reach a daddy long-legs, with painful consequences.

A call comes in from a GP surgery for a child suffering a severe asthma attack and paramedics are called out to a young woman with multiple sclerosis who is in considerable pain. A man with advanced bowel cancer who is struggling to breathe is seen to by a district nurse so as to avoid a visit to A&E. Plus, a patient is having their 10th nose bleed in 11 days.

Calls to the ambulance service reach new heights in the early hours of Saturday morning as the clubs start to empty. A young woman is found intoxicated by the side of the road and an amateur boxer has vomited in his sleep and is difficult to rouse after losing a fight. Paramedics are called for a woman who has gone into premature labour at 32 weeks.

On a Friday night, the paramedics are called out to a man who has reportedly collapsed in the street and isn't breathing. Paramedics also treat a man lying unconscious in an alleyway surrounded by needles who's taken a drug overdose but refuses to go to hospital, and a four-year-old who has a high temperature and a nasty cough. On the same shift, a man is struggling to breathe with an abnormal heart rhythm and a woman has fallen and can't get up. The paramedics need to make sure she hasn't broken any bones.

On a Thursday day shift, a young man has come off his motorbike and slid along the road while not wearing any protective clothing. A young boy is complaining of chest pains; there's a family history of heart problems and his mum is worried about him. On the same shift, a man with only one leg has suspected deep vein thrombosis and needs to be treated in hospital. Paramedics arrive at an address to find a doctor in hospital scrubs holding a baby. It's a father and son and the baby has a worrying cough while a woman is complaining of severe abdominal pain.

A call comes in from the police saying a young man has collapsed outside a nightclub and isn't breathing. It's a category one emergency - the highest priority - meaning there's an immediate threat to life. A young woman is having a sickle cell crisis. This genetic condition makes her normally round blood cells form a sickle shape, sticking together and causing excruciating pain. A woman has the highest blood pressure that one of the paramedics has ever seen, and she needs to go to hospital urgently. A former soldier collapses and is trapped behind a door, and a woman has crippling chest pains. Her condition is a medical mystery that can only be solved with a trip to A&E.

Paramedics treat a woman with a possible bleed on the brain, a baby whose heart is beating extremely fast, a man showing signs of a stroke, and a woman who may have sepsis

Paramedics treat a woman whose defibrillator inside her chest has delivered an electric shock to her heart, and a man who's had bowel surgery who thinks he may have an infection
