Eligibility

Age
18 Years to 80 Years

Inclusion criteria

Inclusion criteria: Individuals of both sexes; Aged 18-80 years; With suspicion diagnosis of obstructive sleep apnea; Who underwent full polysomnography in sleep Institute of San Carlos; Technical data could be analyzed;

Exclusion criteria

Exclusion criteria: Patients who underwent polysomnography, but whose data are not technically acceptable.

Design outcomes

Secondary

MeasureTime frame
Increase in the correlation of the variability of oxygen saturation with the heart rate variability in different degrees of severity of obstructive sleep apnea and were considered mild apnea subjects with apnea / hypopnea index between 5 and 15 events per hour of sleep apnea moderate 16 to 30 events and severe apnea more than 30 events per hour of sleep.

Primary

MeasureTime frame
Presence of subclasses of individuals according to clinical parameters and in different stages of sleep. Measurements: Analysis of oxygen saturation variability and heart rate variability, combined with the other existing methods for analysis of the severity of obstructive sleep apnea, such as the index apnea / hypopnea per hour of sleep, the time of the saturation oxygen spent below 90% and the oxygen desaturation index per hour of sleep.
