súrefniseitrun

Súrefniseitrun, also known as oxygen toxicity, is a condition that can occur when an individual is exposed to excessively high levels of oxygen for prolonged periods. This can happen in various settings, including hyperbaric oxygen therapy, diving, and in neonatal intensive care units. The body's cells rely on oxygen for respiration, but in high concentrations, oxygen can become harmful by generating reactive oxygen species (ROS). These ROS can damage cellular components such as lipids, proteins, and DNA, leading to inflammation and tissue damage.

The symptoms of súrefniseitrun vary depending on the concentration of oxygen and the duration of exposure. In the lungs, it can manifest as substernal pain, coughing, and difficulty breathing, a condition known as pulmonary oxygen toxicity. Central nervous system (CNS) oxygen toxicity can occur with higher partial pressures of oxygen and presents with symptoms like visual disturbances, twitching, nausea, dizziness, and seizures. Ocular toxicity, affecting the eyes, is another potential consequence.

Management and prevention of súrefniseitrun involve carefully controlling oxygen concentrations and exposure times. Medical professionals utilize guidelines and monitoring to ensure safe administration of oxygen therapy. For divers, decompression schedules and limits on depth and time are crucial for avoiding this condition. While oxygen is vital for life, understanding its potential toxicity is essential for safe medical and recreational practices.
