Adaptive servo ventilation is an effective treatment for which sleep-related breathing disorder?

• A. Obesity hypoventilation syndrome
• B. Hunter-Cheyne-Stokes breathing pattern
• C. Nocturnal asthma
• D. Congenital central hypoventilation syndrome

Answer: (B)

Adaptive servo ventilation is designed to treat central sleep apnea by delivering breath-by-breath pressure support that automatically adjusts to the patient’s ventilation. It aims to stabilize the waxing and waning pattern of breathing seen in central pauses, particularly in Cheyne-Stokes respiration, where cycles of increasing and decreasing tidal volumes alternate with apneas. By modulating support to match the patient's actual needs, ASV smooths these cycles and improves both sleep quality and gas exchange. The other conditions listed involve different physiologies—obesity-related hypoventilation, nocturnal asthma (an obstructive process), or congenital central hypoventilation syndrome (a developmental control issue)—and are not the primary targets for ASV, making Hunter-Cheyne-Stokes breathing the best fit.
