Hapnikupööre

Hapnikupööre, also known as oxygen toxicity or oxygen poisoning, is a condition that occurs when the body is exposed to high concentrations of oxygen for an extended period. This can happen in various settings, including high-altitude environments, underwater diving, and medical treatments involving hyperbaric oxygen therapy. The primary risk factor is the prolonged inhalation of oxygen at concentrations above 21%, which is the norm at sea level.

The symptoms of hapnikupööre can vary but typically include visual disturbances, such as seeing halos around lights or experiencing blind spots, as well as neurological symptoms like headache, dizziness, and confusion. In severe cases, it can lead to seizures, coma, or even death. The condition is particularly dangerous for individuals with pre-existing respiratory or neurological conditions, as well as for those who are physically active or have a high metabolic rate.

Prevention and management of hapnikupööre involve limiting exposure to high concentrations of oxygen and ensuring proper ventilation. In medical settings, hyperbaric oxygen therapy is used to treat conditions like carbon monoxide poisoning, but it must be administered carefully to avoid oxygen toxicity. For divers, the use of oxygen tanks is regulated to prevent oxygen toxicity, and decompression procedures are followed to allow the body to expel excess nitrogen safely. Understanding the risks and taking appropriate precautions can help mitigate the dangers associated with hapnikupööre.
