Summary

This completed study used a special imaging method called electrical impedance tomography (EIT) to look at lung function in 100 people with long COVID who have trouble breathing, compared to 50 healthy volunteers. The goal was to see if EIT can detect changes in how air moves through the lungs. This is an observational study, not a treatment, so it aims to improve understanding rather than test a new therapy.
