Supine vs Prone Positioning: Impact on Lung Ventilation and Perfusion #3075984 (License: Personal Use)

This infographic demonstrates how gravitational forces influence alveolar shape and regional blood flow in the lungs depending on body position. In the supine position, ventral (front) regions show better shape matching under gravity, while dorsal (back) regions dominate in the prone position, improving ventilation-perfusion alignment. Foot illustrations (A-F) correlate with corresponding lung zones to reinforce anatomical orientation.

Used in medical education, ICU training, or respiratory therapy resources to explain positional optimization for patients with ARDS or hypoxemia; targets clinicians, students, and caregivers seeking evidence-based positioning strategies.
