Re: Signifigance of Peak flow readings?
I looked at a chart online & see that your numbers were pretty close to normal for your height & age. That said though, "normal" is different for everyone. For those of us with asthma, we measure peak flows against our personal best to see how we are doing. And they always make you do it 3 times, normally you do it 3 times & take the highest of the 3 numbers. That doesn't necessarily mean that you don't have asthma though. Peak flows don't give the whole picture, and are more used as a quick check to see where you stand at a given moment than as a way to diagnose. An asthma specialist might give you a pulmonary function test, or a methacholine challenge test to help diagnose. As far as being worse at night, that is common, although not always the case. When my asthma is not well controlled, am usually at my worst in the even hours (maybe 7-10 pm), but once I go to bed, if I lay still and don't talk or take deep breaths, my asthma settles down & I can sleep thru the night. It is totally an individual thing. What inhalers do you have? Have they helped you?
