I am an EMT working for a northern ambulance service. Around 70-80%, if not more of the jobs we go to are not life threatening incidents, however this does not mean you should not call an ambulance.
If an old person falls ( Doris down jobs we call them) and can not get up, ring us, there is no reason for them to wait on the floor for hours then call relatives who then call us. If they are on the floor call us. Some one earlier mentioned their child having an astma attack and not responding to their inhalers, then call us, breathing problems are given a very high priority and we carry two drugs we can give to help. No ambulance crew is going to critiscise a parent for calling an ambulance becaue their child is having breathing problems. An ambulance with a paramedic crew is not only about transport. If you are in severe pain then call us, we carry morphine and gas and air. A diabetic acting strange then give us a call we carry three drugs we can use.
111 has made our lives even busier. The call takers are not medically trained and just follow a script. When certain key words are used or there is an agregate high score for symptoms they call an ambulance. Weoften arrive at jobs where people are surprised to see us because 111 has called an ambulance. We also arrive at jobs where people are vey ill but dont want to be a bother, usually old people or mothers with young babies.
The vast majority of jobs that are inappropriate for us are down to people simply not knowing when to call for us, there are some entitled people who "pay your wages" but they are in the minority.
Women in labour, well if it is unexpected call us we can get you in much quicker than a taxi and if tehre are any complications again we can help.Yes we all moan about having 9 months to plan for it but I like births, they are yhe only time we take non sick people in and they are usually happy affairs.
The idea of charging for an ambulance sounds good at first but I am very much opposed to it. It would without doubt deter the old ill people, people on benefits, disabled etc who need us. The drunken idiots would not even thing about it and would not pay anyway.
