This cookie is used to detect the first pageview session of a user. A fall in inspired oxygen pressure reduces the driving pressure for gas exchange in the lungs and in turn produces a cascade of effects right down to the level of the mitochondria, the final destination of the oxygen. In this case, medications that improve heart function, such as beta-blockers for heart failure or prescription medications to treat heart arrhythmias, can help improve oxygenation. It is widely used in clinical practice, and denoted as SpO when measured using pulse oximetry. Normal oxygen saturation should be 96 to 97%. Although the percentage of oxygen in inspired air is constant at different altitudes, the fall in atmospheric pressure at higher altitude decreases the partial pressure of inspired oxygen and hence the driving pressure for gas exchange in the lungs. 2016 Jan 15;120(2):236-43. doi: 10.1152/japplphysiol.00476.2015.
