Abstract

Obstructive sleep apnea (OSA) is a sleep disorder with no breathing symptoms due to repetitive upper airway resistance. OSA is a disease that can have significant effects on the cerebral cardiovascular system. Active treatment is needed to prevent these complications. The use of continuous positive airway pressure (CPAP), the standard therapy of OSA, has comparative therapeutic effects. On the other hand, there is no comparison report of the polysomnography (PSG) results before and after CPAP therapy without using a mask. This paper reports a patient who was diagnosed as OSA and used CPAP every night for more than 2 years. The patient showed a decrease in the apnea-hypopnea index from 64.7/h to 12.9/h. In addition, other sleep-related indicators improved significantly. The daily use of CPAP as a treatment for OSA for more than 2 years may improve the PSG results. Constant follow up of PSG will be needed to adjust the appropriate CPAP pressure to patients because there might be a change in the Apnea-Hypopnea Index and other sleep-related indicators for constant CPAP users for at least 2 years.

폐쇄성 수면 무호흡은 반복적인 상기도 저항으로 인해 호흡이 없는 상태를 말하며, 뇌 심혈관계 질환과의 연관성이 있어 적극적인 치료가 필요하다. 대표적인 방법인 지속적 양압기의 치료효과는 많은 연구로 입증되었다. 그러나 지속적 양압기 사용 전과 후의 마스크를 착용하지 않은 상태에서의 수면다원검사 결과를 비교한 것은 없다. 본 증례에서 폐쇄성 수면 무호흡으로 진단된 환자가 2년 이상 꾸준히 지속적 양압기를 사용한 후 재검사를 통해 무호흡-저호흡 지수의 감소(64.7/h에서 12.9/h) 및 그 외 수면관련 지표들도 호전된 결과를 보였다. CPAP의 장기적 사용은 상기도 저항이 감소할 수 있는 기전을 제공하는 것으로 사료되며, 이로 인한 무호흡-저호흡 지수가 변화 가능성이 있으므로 꾸준한 수면다원검사의 추적관찰이 필요하겠다.
