ABSTRACT

Introduction: Obstructive sleep apnea is a disease characterized by recurrent obstruction or collapse of the upper airway. Epworth Sleepiness Scale (ESS) assesses the subjective daytime sleepiness of patients with a questionnaire, being this the most used in nowadays. It’s been found that the arousals produced during sleep disorders can develop excessive daytime sleepiness. Objective: To describe a correlation between arousal index and ESS. Design: Analytic descriptive cross-sectional study. Methodology: Review of sleep study, obtain values of ESS and arousal index and then describe a possible correlation between them. Results: 130 patients were assessed and it was established that there is no statistically significant correlation between the ESS values and the arousal index. Discussion: The subjectivity of ESS can lead to finding some variation in the tested outcomes; on the other hand, it’s important to keep in mind that there are other factors that can improve the daytime sleepiness measured with ESS, such as increased nocturnal hypoxemia. Furthermore, it’s convenient to identify that there are other elements of sleep microstructure that can generate different results when comparing its definition and taking arousal parameters into account, such as the cyclic alternative pattern and its subtypes. Conclusion: There is no correlation between ESS and arousal index.
