I created the same about four years ago, except mine is printed black on yellow, for best visual acutance, and laminated in credit card size so it slips easily into my wallet. It starts: "I'm handing you this because I'm having an asthma attack and I (quite literally) don't want to waste my breath talking." Goes on to name, DOB, address, phone, NOK, GP details, normal drug details, normal PEF/FEV1, says I've never been ventilated or to ITU but have been admitted many times and says I've no known drug allergies. Lists other known medical problems. Adds a quick family medical history and signs off with a suggestion that if I'm having some other emergency to think of this as a steroid card instead. It's saved me many valuable litres of O2 when I've needed them most. To any medics, EMTs etc. reading this - PLEASE do not make us poor asthmatics answer any more questions than absolutely necessary and please make as many of them yes/no questions as possible. e.g. NOT "what drugs do you take?" but "Do you use a reliever?", "Is it salbutamol", "is it bricanyl?" etc. etc. Better still, someone could produce a Q&A sheet that we could just tick boxes on or write the occasional answer - it could even have photos of inhalers for non-english speakers and folks too dumb/disinterested to know/care what they're taking.
