Summary

This study aims to better understand why some patients with ARDS (a severe lung condition) get very sick while others recover. Researchers will collect blood and lung fluid from 50 ICU patients to study their immune cells and inflammation patterns. The goal is to identify different patient types so that future treatments can be more personalized and effective.
