In this Clinical Adventurer episode, we go beyond theairways and dive deep into pulmonary circulation and the mechanics of gas exchange. We’ll break down how the unique design of pulmonary arteries and veins supports efficient oxygenation, and how ventilation, lung volumes,compliance, and airway resistance work together to power every breath. You’ll also learn how oxygen and carbon dioxide move through the body — and what happens when conditions like hypoventilation, hypoxemia, or pulmonary hypertension throw the system off balance. This is the essential respiratory knowledge that helps you level up your clinical practice.
