Home Lung Function Test

Test Overview

A home lung function test uses a peak flow meter to monitor and evaluate any breathing problems you may have on a day-to-day basis. A peak flow meter allows you to measure your peak expiratory flow.

If you have a lung disease, such as asthma, your doctor may test your peak inspiratory flow (PIF) and peak expiratory flow (PEF) to measure the amount of air you can inhale and exhale. This is part of a more complete lung function test.
