Peak Flow Calculator

Calculates an estimated peak expiratory flow rate (PEFR) using basic demographic data including age, height, and sex. The tool applies established medical formulas to predict a user's expected maximum airflow when breathing out forcefully. This prediction serves as a valuable baseline measurement for tracking respiratory function over time, assisting in understanding potential changes in lung capacity. Healthcare professionals or individuals managing chronic respiratory conditions like asthma find this calculator useful. It provides an objective estimate against which actual peak flow readings can be compared during routine monitoring. By establishing an expected range, the tool helps users and clinicians track disease progression or response to treatment more effectively, aiding in proactive management strategies.
