Central Nervous System Oxygen Toxicity and Hyperbaric Oxygen Seizures

Area of Science:

• Hyperbaric medicine
• Neuroscience
• Biochemistry

Background:

• Hyperbaric oxygen (O2) therapy, while beneficial, poses a risk of central nervous system (CNS) O2 toxicity.
• Understanding the molecular mechanisms of CNS O2 toxicity is crucial for patient safety.

Purpose of the Study:

• To review existing literature on CNS O2 toxicity.
• To elucidate the physiological changes and molecular mechanisms underlying CNS O2 toxicity.

Main Methods:

• A comprehensive literature review was conducted across various scientific fields.
• Analysis of physiological changes induced by increased oxygen partial pressures (Po2).

Main Results:

• Elevated Po2 can lead to CNS O2 toxicity by overwhelming protective mechanisms and overstimulating neural networks.
• Specific CNS regions exhibit varying susceptibility to oxygen toxicity.
• Severe cases of CNS O2 toxicity can result in seizures and fatality.

Conclusions:

• Increased scientific evidence highlights the need for further investigation into CNS O2 toxicity.
• The growing use of hyperbaric O2 treatments necessitates continued research to ensure therapeutic safety.
