Nocturnal oxygen saturation is associated with all-cause mortality: a community-based study.

ABSTRACT:

Study objectives

Observational studies have demonstrated the association between the single-point measurement of oxygen saturation (SpO₂) level and mortality in the general population. This study aimed to evaluate whether nocturnal SpO₂ level could predict all-cause mortality in a community-based population.

Methods

The study samples were obtained from the Sleep Heart Health Study, which included 2,280 men and 2,606 women (mean age, 63.8 ± 11.1 years). A pulse oximeter based on overnight in-home polysomnography was used to monitor SpO₂ levels during total sleep time (SpO_2-TOTAL). Multivariable Cox proportional hazards analysis was performed to examine the association between nocturnal SpO₂ and all-cause mortality.
