Simple 75-Second breath test could revolutionize asthma and COPD diagnosis

This study is testing a new, easy way to diagnose asthma and COPD using a handheld device that measures carbon dioxide in a person's breath. Instead of the current uncomfortable and time-consuming lung tests, participants simply breathe normally into the device for 75 seconds. The goal is to see if artificial intelligence can accurately identify the correct diagnosis from the breath patterns, which could make diagnosis faster and more accessible in community clinics.
