In this episode of Clinical Adventurer, we uncover what really happens when oxygen and carbon dioxide move through the lungs and bloodstream. You’ll learn how perfusion andventilation-perfusion (V/Q) matching keep gas exchange efficient — and what happens when they don’t. We’ll break down oxygen transport, hemoglobin affinity, and the body’s smart adaptations to low oxygen levels. Plus, we’ll explore how carbon dioxide is carried and the chemistry that drives it all. This is the essential gas exchange knowledge that connects the physiology to what you see at the bedside.
