Hypertension indicates?

• A. Hypercapnia
• B. Hypotension
• C. Hypoxemia
• D. Normal oxygenation

Answer: (C)

Pulmonary hypertension signals elevated pressures in the pulmonary circulation that typically arise from chronic low oxygen levels in the lungs. When PaO2 is reduced, the small pulmonary arteries constrict (hypoxic pulmonary vasoconstriction) and, over time, can remodel, increasing vascular resistance and pressure. This higher pressure state reflects impaired oxygenation, not normal oxygenation, and is not directly about systemic blood pressure or CO2 levels. So hypertension in this context indicates hypoxemia.
