Oxygen-Enriched Atmospheres: Applications and Examples

• Earth's Atmosphere: ~21% oxygen, essential for life.
• Hyperbaric Oxygen Therapy (HBOT): Breathing pure oxygen in a pressurized chamber; treats decompression sickness, carbon monoxide poisoning, severe burns.
• Oxygen Tents: Historically used for respiratory illnesses (pneumonia, TB); still used in emergencies for respiratory distress.
• Oxygen Concentrators: Remove nitrogen to deliver pure oxygen for chronic conditions (COPD, emphysema).
• Oxygen Cylinders: Portable compressed oxygen for patients needing regular supplemental oxygen (travel, exercise).
