What is Oxygen Toxicity

High concentrations (70% or more) and for a long time (48 hours) consists of oxygen toxicity in the lungs of adults given continuous oxygen. The main pathological findings of intra-alveolar hemorrhage, alveolar and interstitial fibroblastic proliferation and hyaline-membrane husule is that the tissue.

And adults that use high concentrations of oxygen for a long time, but some of the toxicity of oxygen occur. The role of personal factors in the development of this disease has.

Clinical symptoms vary according to the disease requiring oxygen therapy. Usually, these patients with acute respiratory failure (dyspnea, syanoz, wheezing and respiratory acidosis further periods: drowsiness, mental disorders and coma) has symptoms.

Radiologic manifestations of the disease varies according to reason. Oxygen therapy is applied is one of the rapidly growing abnormal radiographic interstitial fibrosis in oxygen toxicity.

Prevansiyon and treatment of

Oxygen treatment when necessary to ensure that arterial blood pressure of 65-75 mm Hg, oxygen should be given oxygen. Frequent arterial blood analysis, and accordingly by adjusting the inspired oxygen concentration of 65-75 mm Hg, arterial oxygen pressure and thus tried to keep the oxygen toxicity is avoided. Hypoxemia in some patients, however, even though treatment is given for the high concentration of oxygen to meet the needs of physiological levels of oxygen in arterial blood is low. And the fatal hypoxemia (arterial blood oxygen pressure of less than 40-50 mm Hg) are available. Oxygen concentration of oxygen toxicity in these patients, fearing azaltmamalıdır definitely. Hypoxemia because the patient dies. Hypoxemia should be treated first and then the toxicity of oxygen. These patients are treated in intensive care units.
