ABSTRACT

Introduction: Mexico City is located at an altitude of 2,240 meters above sea level, reason for which oxygen pressure is lower than at sea level. There is population of 403,511 elderly people over 70 years in whom arterial oxygen saturation values (SaO2) have not been established. Objective: To determine oxygen saturation in the elderly population of Mexico City. Methods: Elderly people over 70 years living in Mexico City were included. Non-smokers or with a smoking index less than 10. Those with cardiopulmonary disease, anemic syndrome and cancer were excluded. Oxygen saturation was measured with a pulse oximeter. Results: 50 men and 50 women were studied, age average of 80.67 ± 5.92 years; 20% of the women and 58% of the men were smokers. The SaO2 average of the population studied was 95.25 ± 1.65%, with equal results in men and women 95.22% and 95.28% respectively (p = 0.36). Persons without precedent versus those with precedent of smoking SaO2 was greater, 95.73% and 94.6% respectively (p = 0.24). We compared the population between 70-79 years of age with that of 80 years and older, SaO2 was 95.64% in the first group and 94.86% in the second (p = 0.14). Conclusions: The elderly population over 70 years of age residing in Mexico City without cardiopulmonary disease have mean arterial oxygen saturation of 95%.
