Introduction Age may have influence in the response of the respiratory center and the dynamic systems that control breathing, so that younger patients presented respiratory events of shorter duration, compared with older patients,warning mechanisms which were more disturbed, they would present longer events. Objectives: To assess the influence of age in patients with sleep apnea–hypopnea sleep (OSA) on quantitative and qualitative profile (duration) of respiratory events. Materials and methods Data were collected prospectively from 81 patients polygraph SAHS during the months of September to November 2008. We evaluated the correlation between age and the duration and number of apneas. We used Spearman’s rho correlation. SPSS vs. 15.0 was used for statistical analysis, a value considered significant at P 0.05. Results A significant correlation between age of patients with SAHS and the duration and number of respiratory events, with a correlation coefficient of 0.447 and 0.21 respectively. Conclusion In OSAS patients was evidenced a longer duration of respiratory events in older patients. The cause is not clear and it could be in relation with respiratory control mechanisms or also with the natural history of the disease.
