Prevalence of OSAS in Chinese Elderly and Its CPAP Compliance

As OSA may increase the risk of cardiovascular mortality, all elderly subjects with AHI ≥ 15 or those with AHI ≥ 5 plus either cardiovascular risk factors or ESS score ≥ 10 received patient education program. Elderly subjects who agree for home CPAP treatment were prescribed nasal CPAP units with time clocks to assess objective compliance (run time). ESS, sleep apnea specific quality of life index (SAQLI), and cognitive function tests were performed at baseline, 3 months, 6 months and 12 months after CPAP treatment.
