Cheers mate. Ditto on both your comments. The bottle in the fridge is very handy.......spot the sticker on the front door and straight to the fridge for a comprehensive history. Saves a load of time, especially in cases where the patient is alone and unconscious. Also, no world in which I'd push an asthmatic to talk if they were bad, I'll be the one telling the patient not to try and talk but to concentrate on their breathing, and the peak flow goes out of the window fairly early on. Is this because I am incredibly altruistic and thoughtful........well......a bit......on a good day......but also because like Tom says, asthmatics have a nasty habit of going wrong......I'm not doing anything to encourage them!!
