2) Prepare yourself psychologically to be verbally abused, spat at, assaulted, and not be able to react how you normally would were you not in uniform.
3) Realise that you are on your own. Management will very rarely support you should things go wrong. Their good name is far more valuable than you. You're just an ambulance driver remember?
4) CYA. It pains me deeply to say it, but if in any doubt as to the seriousness of a patients condition, cover your arse and take them to the fucking hospital. See point 3 above and 5 below and remember, nobody thanks you for doing the patient and the hospital a favour by offering advice to someone with a cold instead of taking them to hospital.
5) Complete your paperwork as if it's going to go to coroner's court.
6) Some people will assume that you know everything there is to know about their obscure medical condition. Handle the news that your patients has Proteus Syndrome in two ways. Either nod sympathetically and take them to hospital without further discussion of the syndrome to avoid being exposed as a fraud, or politely explain that you know absolutely nothing of their syndrome. Not only that, but you have never even heard of it, not vaguely. However, you should explain that if they cut their leg off you're their man.
7) Never panic. If you can't help but panic, then never let people detect even the slightest hint of panic. It is important that you look calm-as-fuck at all times. You need to look like not a day goes past when you don't get sent to a bus that's flipped over onto it's roof, slid over a cliff and landed in a river...then caught fire...then been attacked by a huge pack of rabid dingos. Don't let anyone see that you are thinking 'what the fuck am I going to do here!?'. Stroll over to the scene with your hands in your pockets, carefully put on your high-visibility jacket, adjust your sunglasses, and hope to fuck that backup arrives sooner rather than later (hold on this is St John, we will have to request backup as they will only have sent one ambulance to 'investigate').
8) If you are ever unsure how to handle a situation, do not panic (see above). People may have called you because they thought they didn't know how to get Jim out from behind the awkward bit of piping at the steel factory, but they probably do. Don't worry, they will figure it out and let you know then you can steal the idea. Sometimes remaining silent and thoughtful can be a handy. If that technique doesn't appear to be working try the "hmmmm what do you think?" or "hmmmm you know what's painful jim, you let us know how we should get you out?". Always works when you're stuck for a solution to those sticky ones..
9) When you arrive at hospital and the triage nurse walks past you like you are Patrick Swayze from Ghost and attempts to take a history directly from the patient who they have yet to realise has advanced dementia, do not get upset. They are not showing a complete contempt for you and your profession, the triage nurse is merely attempting to cut out the middle man and go directly to the root of the problem. Makes sense.
Triage Nurse: "What's brought you in today then love?"
Lady with Dementia: "Brought me where? Who are you?"
Triage Nurse: "Do you have any pain?"
Lady with Dementia: "Pain? No? I don't think so"
Triage Nurse: "Do you know what day it is today lovely?"
Lady with Dementia : "No, is it Sunday?"
Triage Nurse: "Do you know who the Prime Minister is?"
Lady with Dementia: "Who?"
Triage Nurse: "Do you have any allergies?"
It doesn't matter that you've obtained a thorough and detailed history of the problem from the patient's family and the staff at the nursing home (as is your job), the triage nurse will be able to extract a better history from the lady. Calmly let her persevere with this until she gives up and comes back to speak to you, then calmly correct all her misconceptions one at a time as she tries to type them into the computer.
10) If you injure yourself operating a piece of ambulance equipment, quickly read the operations manual on how to correctly operate the piece of equipment before you complete the incident report.
11) If you attend someone who is seriously ill at a doctors surgery, do not expect any useful assistance from the doctor. Don't get me wrong, GP's are great, but it's not really their thing this emergency stuff. Expecting a GP to know how to handle someone who collapses through the door without first referring to a textbook, is like expecting a neurosurgeon to run a GP surgery, or an obstetrician to perform a heart bypass. It's just not their thing, they've learnt it, but they've not had to do it in years. Some GP's are great at this emergency stuff, but quite often you might need to politely suggest the correct treatment for the patient.
