This could be a sign your asthma is getting worse. Asthma exacerbation severity can be quantified by comparing a patient’s current peak expiratory flow rate (PEFR) to their most recent personal best value. In the absence of a known recent personal best, this calculator can be used to estimate an expected “personal best.”. From changes in recorded values, patients and doctors may determine lung functionality, the severity of asthma symptoms, and treatment.

Peak flow measurement is mostly done by people who have asthma. Peak flow measurement can show the amount and rate of air that can be forcefully breathed out of the lungs. The measurement should be started after a full lung inhalation. Estimated/Expected Peak Expiratory Flow (Peak Flow) Quantifies asthma exacerbation severity. Use in patients age 5-80 years with asthma. Useful in patients who do not know their baseline peak expiratory flow rate (peak flow).
