Summary

This study used a special lung imaging technique called electrical impedance tomography (EIT) to see how air moves in the lungs of people with post-COVID breathing trouble. Researchers compared 100 patients who had COVID-19 and still felt short of breath with 50 healthy volunteers. The goal was to find differences in lung ventilation that might explain ongoing symptoms.
