Abstract
This text outlines a structured approach to diagnose and manage hypoxemia in dogs and cats using pulse oximetry and arterial blood gas (ABG) analysis. It details the main causes-low FiO2, hypoventilation, and venous admixture-and explains how tools like the A-a gradient, partial pressure of oxygen/FiO2 ratio, and respiratory-rate oxygenation index help assess severity and guide therapy. Stepwise ABG interpretation is emphasized to tailor oxygen support, from conventional methods to high-flow oxygen therapy or mechanical ventilation in severe cases. Continuous monitoring improves prognosis and informs escalation of care.
