#Side effect of too much oxygen trial#
A Randomized Trial of Long-Term Oxygen for COPD with Moderate Desaturation. The New England Journal of Medicine.
However, recent research reviewed in this monograph demonstrates that surprisingly short exposures to oxygen can alter long term biochemical indicators of oxidant stress and may adversely affect outcomes.
With continued exposure, damage to the lung tissues may cause fluid leakage into the air sacs, accompanied by increasingly severe shortness of breath. Irritation of the large airways caused by the highly concentrated oxygen provokes this symptom. Coughing is typically the first symptom of pulmonary oxygen toxicity. The risk of pulmonary oxygen toxicity proves highest when inhaling pure oxygen for several hours to days. The risk for this side effect of oxygen therapy comes into play primarily when patients on home treatment increase the oxygen flow rate to a level higher than prescribed. Prolonged administration of highly concentrated oxygen can potentially damage the lung lining tissues and air sacs, a condition known as pulmonary oxygen toxicity. When it comes to oxygen therapy, there can be too much of a good thing. Starting patients with hypoxic respiratory drive on a low concentration of supplemental oxygen typically helps avoid this potentially serious side effect of oxygen therapy.The brain respiratory center monitors levels of oxygen and carbon dioxide in the blood 1.
