THis may sound like a stupid question but hey I'll ask it anyway!
I've just got a new peak flow meter after my cons nearly had a heart attack when I said I'd had my old one for about 10 years (not sure why as it still works as far as i can tell but hey!). So this one is completely different to the old one - it's a vitalograph one, and works to the new scale. Anyway my question is, it didn't come with a seperate mouthpiece - are they supposed to, or do I need to get that seperately or do I just use it as it is? It looks like I need one, and I had one for my old one, but as I say, this is a completely different one and not having had a new one for years I'm not sure what the norm is anymore! Obviously they have disposable mouthpieces at docs / costa but just not sure what should happen at home.
Any advice welcomed!!
Thanks in advance!
