Understanding Hypoxemia: Causes and Case Studies

This chapter explores the complexities of hypoxemia, focusing on the various causes such as low inspired oxygen, VQ mismatch, and intra-pulmonary shunts. Through clinical case studies, the dialogue examines how physiological mechanisms and pre-existing conditions contribute to hypoxemia and the implications for treatment. Key concepts like hypoxic pulmonary vasoconstriction and the A-a gradient are also discussed, emphasizing their relevance in managing respiratory distress.
