Peak Flow Meter Results
Is it common to feel light-headed after blowing too hard into a peak flow meter? Does it have anything to do with the asthma? (if the reading is in the green zone) Thanks.
Light-headedness may occur with particularly forceful expiration, and is not specifically associated with asthma. If it is mild, then it is not likely to be a cause for much concern. However, you should make your physician aware of its occurrence.
