Asthma sufferers should use a peak-flow meter every day to assesses lung function. To use it, simply stand up, take a deep breath, put the meter in your mouth and blow as hard and long as possible. Repeat 2 times, then record the best of the 3. Readings that are 80%-100% of your “personal best” are ideal. Any lower and it’s a sign that your asthma is getting worse and you should call your doctor.
