Hypoxemia in Clinical Practice: Mechanisms, Diagnosis, and Management Strategies
Hypoxemia, defined as a reduced level of oxygen in arterial blood, is a critical clinical condition that can result from a variety of respiratory and systemic disorders. It is commonly encountered in emergency and critical care settings and requires prompt identification and management to prevent organ dysfunction and mortality[1]. This article explores the mechanisms underlying hypoxemia, including ventilation-perfusion mismatch, diffusion impairment, hypoventilation, and shunting. It also discusses diagnostic approaches such as arterial blood gas analysis and pulse oximetry, along with imaging and laboratory investigations. Furthermore, the article reviews management strategies, including oxygen therapy, ventilatory support, and treatment of underlying causes. Understanding hypoxemia is essential for clinicians to ensure timely intervention and improved patient outcomes
