Quantitative descriptive study of oxygen saturation in women living at altitudes greater than 2800 M.A.S.L. Huancavelica Peru

The objective of the research work was to determine the oxygen saturation (SpO2) in women of childbearing age who live at altitudes greater than 2800 meters above sea level (m.a.s.l) Huancavelica 2021. The study was observational, prospective, cross-sectional, in 151 healthy women of childbearing age, from 18 to 49 years old, the SpO2 was evaluated, through a pulse oximeter, to all women who attended the consultation between July and August of the year 2021, women without cardiopulmonary pathology were considered within the study group and those who accepted take part. Results: the average of the SpO2, of those who live between 2819 - 3499 m.a.s.l. is 93.72% and between 3500 - 4200 m.a.s.l., it is 90.85%; the minimum SpO2 was 85% and 83% respectively, the maximum SpO2 was 99% in both altitude floors. According to age, 92.91% were between 18 and 19 years old, 93.09% between 20 and 34 years old, and 91.74% between 35 and 49 years old. The average SpO2 of the pregnant women was 92.29% and in the non-pregnant women 92.67%, the minimum SpO2 was 88% and 83% respectively, while the maximum value was the same in both groups 99%. Conclusion: the inhabitants show lower saturations at higher altitudes, and it is observed to decrease after 35 years old, no difference is found between pregnant and non-pregnant women.
