ARDS Biomarkers: Blood, Alveolar, and Bronchial Indicators Explained #3624556 (License: Personal Use)

The image depicts the pathophysiological cascade of Acute Respiratory Distress Syndrome (ARDS), highlighting measurable biomarkers in peripheral blood (SP-A, SP-B, SP-C, SP-D, KL-6, CC16) and within lung tissue-specifically surfactant proteins from alveolar type II cells and KL-6/CC16 from bronchial epithelium. Arrows indicate how systemic and local biomarker profiles reflect disease severity and progression, supporting early diagnosis and monitoring.

Used in medical education, clinical guideline pages, or research summaries on ARDS diagnostics; targets pulmonologists, critical care physicians, and biomedical researchers seeking visual reinforcement of biomarker localization and utility.
