Hello out there! I've seen several cool peak flow meter gadgets on other websites, where do you find those and how do you customize them to your red, yellow and green zones?? Please help. I'm very new to blogging and would very much like to customize my page.
Talk to your asthma doctor about getting a digital peak flow meter. If you don't use your pf meter very much, then it wouldn't be very wise to invest in a digital one. But if you use it often, it might make recording your measurements easier. Just depends on how often you use it. I have the old fashioned kind.
