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.
