High altitudes can cause low oxygen saturation levels or desaturation of an individual's blood. It happens because of low atmospheric pressure at high altitudes. Oxygen saturation levels refer to the extent hemoglobin is bound or saturated to oxygen.
High altitude environments can be debilitating to unacclimatized individuals exposed to elevations above 3,000 m (9,843 ft) for periods ranging from several hours to days. Moderate hypoxia induces substantial alterations in physiological and psychological parameters within a few hours
