Objective: knowing the physiological changes to lower barometric pressure in acute situations, since the amount of oxygen is reduced in the atmosphere, the pressure of inspired oxygen and therefore oxygen uptake. In Colombia about half of the population is between the heights of 1500-3000 meters above sea level, necessary for physiological adaptations begin by falling barometric. Materials and methods: an observational study was conducted where they participated voluntarily 15 subjects, graduate students from the National University of Colombia in Bogotá. The age range was between 23 and 33
years, blood pressure measurements, lactate, hematocrit, oxygen saturation and heart rate were performed. These physiological indices were measured on two occasions; 2600
meters and 3800 meters. Results: heart rate d differ significantly between the two levels with p = 0.0001913 but lactate there were no significant differences, with p = 0.73 in the two levels, the Oxygen saturation by pulse oximetry was a difference significant compared taken at 2600 m with respect to 3800 m with p = 0.0006787, hematocrit increased significantly from 2600 m to 3800 m with a p-value = 6.078x10-07, in blood pressure there
was no difference significant in the two measurements. Conclusions: exposure to high altitudes lead to significant changes in hematocrit, oxygen saturation and heart rate as
compensation measures to environmental demands, which must be taken into account for adaptive processes and physical activity.
