Before and after a breathing treatment your peak expiratory flow rate (PEFR) will be measured with a meter. It is best to conduct this measurement while standing, if your condition permits. You’ll be asked exhale forcefully and rapidly with lips sealed around the meter’s mouthpiece. This allows your emergency medicine (EM) doctor to determine if there has been measurable improvement in your breathing. Age and height are factors important in determining normal PEFR.
