Hypoxemia is defined as what?

Hypoxemia is defined as what?

• A. High oxygen in blood
• B. Inadequate oxygen in the blood
• C. Normal oxygen levels
• D. Excess carbon dioxide in blood

Answer: (B)

Hypoxemia means there isn’t enough oxygen in the arterial blood. It is defined by a low arterial oxygen tension (PaO2) and often a reduced oxygen saturation (SaO2) on monitoring. This contrasts with high oxygen levels, normal oxygen levels, or excess carbon dioxide. Clinically, hypoxemia indicates insufficient oxygen delivery to tissues and can arise from issues like ventilation-perfusion imbalance, diffusion problems, or hypoventilation. The phrase “inadequate oxygen in the blood” best captures what hypoxemia describes.
