Sauerstoffverfügbarkeit

Sauerstoffvergiftung refers to the toxic effects of breathing excessive concentrations of oxygen. While oxygen is essential for life, prolonged exposure to high partial pressures can lead to cellular damage, particularly in the lungs and central nervous system. This condition is most commonly encountered in scenarios involving hyperbaric oxygen therapy or deep-sea diving.

In the lungs, high oxygen levels can cause inflammation, fluid buildup, and impaired gas exchange, a condition known as pulmonary oxygen toxicity. Symptoms may include chest pain, coughing, and shortness of breath. In more severe cases, it can lead to acute respiratory distress syndrome.

Central nervous system (CNS) oxygen toxicity is a more immediate concern during hyperbaric exposures. It can manifest as visual disturbances, ringing in the ears, nausea, muscle twitching, and in extreme situations, convulsions. These neurological symptoms are related to the increased partial pressure of oxygen affecting brain function.

The risk of oxygen toxicity is primarily determined by the partial pressure of oxygen and the duration of exposure. Lower concentrations or shorter exposure times generally pose little to no risk. Medical professionals carefully manage oxygen therapy and diving protocols to stay within safe limits and prevent adverse effects. Divers often use breathing gas mixtures with lower oxygen percentages at greater depths to mitigate this risk.
