I've been reading about oxygen supplementation and have a question about the effects of oxygen supplementation in case of pneumonia.
Patients with aspiration pneumonitis or pneumonia may progress to acute lung injury and acute respiratory distress symptom (ALI/ARDS), which is characterized by hypoxemia and respiratory failure. - https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5564131/
Oxygen supplementation is one way to help patients who cannot breathe adequately on their own. - https://www.cochrane.org/CD006607/ARI_the-effectiveness-of-oxygen-for-adult-patients-with-pneumonia
Normal arterial oxygen is approximately 75 to 100 millimeters of mercury (mm Hg). Values under 60 mm Hg usually indicate the need for supplemental oxygen. - https://www.mayoclinic.org/symptoms/hypoxemia/basics/definition/sym-20050930
Supplementary oxygen is routinely administered to patients, even those with adequate oxygen saturations, in the belief that it increases oxygen delivery. But oxygen delivery depends not just on arterial oxygen content but also on perfusion. - https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3218982/
Does oxygen supplementation in case of pneumonia cause (positive or negative) effects other than possibly preventing hypoxemia?
