Researchers track Long-Term lung damage in critical COVID patients

This study aims to understand how often severe COVID-19 pneumonia leads to permanent lung scarring (pulmonary fibrosis). Researchers will review the medical records of 200 critically ill patients to identify who developed fibrosis, what factors increased the risk, and how it affected their recovery—specifically how many days they survived without needing a breathing machine. The goal is to gather knowledge to help future patients, not to test a new treatment.
