oksygenförgiftning

Oksygenforgiftning, also known as oxygen toxicity, is a condition that can occur when a person inhales too much oxygen at elevated partial pressures. This typically happens in environments with higher than normal atmospheric pressure, such as during scuba diving or when using hyperbaric oxygen therapy. The excess oxygen can interfere with normal cellular functions, particularly in the lungs and the central nervous system.

Symptoms of oxygen toxicity can vary depending on the duration and level of oxygen exposure. Pulmonary oxygen toxicity primarily affects the lungs and can manifest as chest pain, coughing, and shortness of breath. It develops over longer periods of breathing high concentrations of oxygen. Central nervous system (CNS) oxygen toxicity, also known as the Paul Bert effect, occurs more rapidly and at higher partial pressures. Symptoms can include visual disturbances, ringing in the ears, nausea, muscle twitching, and in severe cases, convulsions or seizures.

The risk of oxygen toxicity is managed by limiting the partial pressure and duration of oxygen exposure. For divers, this involves adhering to dive tables and limits for oxygen use at different depths. In medical settings, hyperbaric oxygen therapy protocols are carefully designed to minimize risk. Treatment for oxygen toxicity involves reducing or ceasing oxygen exposure. Prompt recognition and management are crucial to prevent serious complications.
