The spread of the single values within the measurement interval is high (in single cases up to 17%-points) in case of insufficient acclimatization. Brain cells can begin to die within five minutes of oxygen deprivation. The most common causes of hypoxaemia are respiratory disease such as emphysema, pulmonary edema, high altitude, shock . For instance, it is often helpful for people who suffer from chronic lung disease, who may need repeated assessments of oxygen levels. Your body tightly regulates the amount of oxygen saturation in your blood, because low blood oxygen levels (hypoxemia) can lead to many serious conditions and damage to individual organ systems, especially your brain and heart. Town B has only 10 Ubers. Oxygen saturation is the measure of how much oxygen is traveling through your body in your red blood cells. The amount of oxygen in your blood is described by the "oxygen saturation" - which is literally the percentage of your blood that is 'fully loaded' with oxygen. However, this isnt always the final or best answer. This oxygen to altitude chart extrapolates the amount of oxygen (as a percentage) to real altitude.
