Correct Method for using a peak flow meter.

When you are given a peak flow meter, there are "average" readings on the form enclosed. HOWEVER, I NEVER go by these values because each person is as different as a snowflake. To get your reading, perform the test on a day when you are feeling your best. Do it 3 times. The higest number will be your baseline from now on. Perform the peak flow upon rising & again in the evening. If you keep a diary, you will start to notice patterns after about a month. The small pocket calendars are the best because you can carry it with you. Write the am reading at the top & the pm reading at the bottom. Also make a note if it is raining or sunny, pollen content, temp, humidity, & make a little note if you are already having breathing problems. After about a month, you will note that your readings may be higher in the am than during the pm because you have been out in the elements & exposed to triggers. You may also note that it may be higher upon rising. If this is the case, then you need to check your bedroom for dust mites (cover mattress & pillow), purchase HIPA filter for your heat & a/c system, try blinds instead of curtains, etc. When you go to see your MD, take the calendar w/you. This will give the MD an insight on your asthma activity.

An example of different variables: If you had 3 women, all age 42 (for example), all the same heighth, weight ... it would depend on if how active each woman was, whether she smoked or not, any illnesses she might have. I am 52 yrs old, 5'4", 130 lbs & my usual is around 600 which is more than the enclosure indicates. That's because I do lung exercises during my asthma mgt teaching.

Hope this info helps. Sorry to take so long in answering. Our computer is in my son's room & he's been ill the last several days. Let me know if you need any more info. I'm going to try to post some more asthma educational info on Wednesday. Take care!
