Summary

This study looks at 170 adults with severe breathing failure (ARDS) in the ICU. Researchers will take a blood sample to measure a clotting marker and then check if those who develop a pulmonary embolism (a blood clot in the lung) have higher levels. The goal is to see if this blood test can help doctors detect dangerous clots earlier.
