Are there instructions online for that model of peak flow meter? The only one I'm familiar with is when I see the doctor, the one there has a red thing I have to slide to zero then do 3 attempts at blowing and it's the best of 3 that counts. I don't understand the charts the averages are based on. I can never get anywhere near what the chart predicts. I think the point of having one at home is to plot your peak flow over the weeks to look for any trends and variations, not necessarily as a comparison of your results against the predicted average. Perhaps you can ask your pharmacist or doctor for advice?

As HungryHufflepuff say's it's to record your peak flow over time to see if there are any trends like better in the morning or worse at night etc.

I am lucky if I can reach 200 these days on PF. As aleady suggested take reaings morning and evening and keep a recod and see of a trend emerges. Being consistent seems to be the objective.

Only details your repsiratory team can answer. I am 23% projected which means I think that I only have 23% of what I would have if I had healthy lungs. It mihjt get it into perspective for you but its irrelevant i you think about it. You are where you are right now.

As HP mentions, in the uk we normally have a simple hand held tube & set the red arrow on zero, take three readings and record the best of the three night & morning before inhalers. It's a handy tool in asthma particularly.

480 and I'd be able to jump for joy!

Maybe 500 at a guess. You can only get an average because every 5'7, 58.5 year old male is different, weight, lifestyle, fitness & diet on different days all play a part.

Google 'peak flow' for more precise info, we're not medics here, just patients offering help & support where we can

that makes sense the charts i have seen online are a tad confusing.. i hope that between 450 and 500 is good for me
