Hypoxia and Hypoxemia: Mechanisms and Etiologies - ABG Interpretation

Explore the mechanisms and etiologies of hypoxemia in this comprehensive 31-minute video lecture. Learn about impaired diffusion, ventilation/perfusion mismatch, and shunting. Delve into gas exchange processes, V/Q matching and mismatching, pulmonary embolism, and Tetralogy of Fallot. Understand the influence of shunt fraction on response to changes in FiO2. Develop a systematic approach to hypoxemia and examine various etiologies through patterns of radiographic abnormalities. Gain valuable insights into ABG interpretation and enhance your understanding of respiratory physiology.
