Examples of conditions that can affect your oxygen saturation include: Oxygen saturation is measured in one of two ways: an arterial blood gas test (ABG or Sa02) or pulse oximetry (Sp02). Although air contains 20.9% oxygen at all altitudes, lower air pressure at high altitude makes it feel like there is a lower percentage of oxygen. This level is measured by an oximeter that clips to the tip of a finger. By clicking Accept, you consent to the use of ALL the cookies. Unlike the ABG test, pulse oximetry does not involve a needle (non-invasive).

This explains why athletes for endurance sports will often train at higher altitudes: the demands they put on their body while having less oxygen activates the feedback loop for increased production of red blood cells (and Haemoglobin). As the elevation increases, SpO2 will gradually decrease. : Light can be blinding on the high altitude salt flats, or dense and green in the rainforest.
