Study Notes
Oxygen Toxicity: Effects and Considerations
- Oxygen toxicity can be recovered from in the long term, with protocols in place to avoid its effects in various fields, including diving, hyperbaric medicine, neonatal care, and spaceflight.
- The rarity of seizures due to oxygen toxicity has increased due to these protocols, with pulmonary and ocular damage largely confined to managing premature infants.
- Recreational use of oxygen in oxygen bars has raised concerns, with the FDA warning individuals with heart or lung disease against using them.
- Scuba divers use breathing gases with high oxygen content, requiring specific training.
- Oxygen toxicity can be classified by the affected organs into three principal forms: central nervous system, pulmonary, and ocular.
- Central nervous system oxygen toxicity can cause seizures, rigidity, convulsions, and unconsciousness, especially concerning for divers under greater than atmospheric pressures.
- Pulmonary oxygen toxicity results in lung damage, causing pain and breathing difficulties.
- Ocular oxygen toxicity can lead to eye alterations, myopia, and partial detachment of the retina.
- Oxygen toxicity can cause oxidative damage to various organs, including red blood cells, liver, heart, endocrine glands, kidneys, and general cellular damage.
- Unusual circumstances, such as spaceflight, may lead to bone damage due to high oxygen concentrations.
- Central nervous system oxygen toxicity manifests as visual changes, ringing in the ears, nausea, twitching, behavioral changes, and seizures.
- Pulmonary oxygen toxicity symptoms include inflammation, coughing, shortness of breath, pulmonary edema, reduced lung function, and hypoxemia.
