How To Avoid Oxygen Toxicity

Oxygen toxicity happens when tissues are exposed to too much oxygen for too long, causing damage—mainly affecting the lungs and nervous system. It’s a concern mostly in medical, diving, or hyperbaric environments.

How to Avoid Oxygen Toxicity:

Use Oxygen Carefully
- Only use supplemental oxygen if prescribed.
- Avoid unnecessary high oxygen concentrations, especially for extended periods.
Follow Medical Guidance
- For patients on oxygen therapy, follow prescribed flow rates and duration.
- Regularly monitor blood oxygen levels (SpO2) and blood gases as recommended.
Limit Exposure in Hyperbaric Environments
- Divers should follow dive tables and limits for oxygen partial pressure.
- Avoid breathing 100% oxygen at high pressure for too long.
- Use appropriate gas mixes (e.g., Nitrox) and equipment.
Avoid Prolonged High FiO2 in Medical Settings
- Healthcare providers aim to maintain oxygen saturation within safe ranges (usually 92-96%) to avoid excess oxygen.
Monitor for Symptoms
- Symptoms of oxygen toxicity include visual changes, ringing in ears, nausea, muscle twitching, dizziness, or seizures.
- Seek immediate help if symptoms appear.

Summary

Use oxygen only when necessary and at the lowest effective concentration.
Follow safety protocols for oxygen therapy and diving.
Regular monitoring prevents excessive oxygen exposure.
