In managing suspected sleep-disordered breathing, which therapy improves daytime sleepiness and reduces cardiovascular risk?

• A. CPAP
• B. CBT-I
• C. OSA surgery
• D. Melatonin

Answer: (A)

Continuous positive airway pressure acts as a pneumatic splint to keep the upper airway open during sleep, preventing obstructive apneas and hypopneas that cause oxygen desaturation and arousals. This improves sleep continuity, reduces daytime sleepiness, and, with good adherence, lowers cardiovascular risk by decreasing nocturnal blood pressure surges and sympathetic activation linked to apneas. Other options address insomnia, have variable effects on airway collapse, or are not suitable for treating airway obstruction. So CPAP best achieves both improved daytime sleepiness and reduced cardiovascular risk.
