Hyperbaric Oxygen Therapy

Basics

Administration of 100% oxygen at >1 atm (typically 2–3 atm)
Mechanisms of action:
- Increases oxygen availability at the cellular level:
  - Breathing 100% oxygen at 3 atm supplies enough dissolved oxygen to support life without hemoglobin
- Compresses formed gas bubbles (in cases of air embolism or decompression sickness)
2 types of hyperbaric oxygen chambers:
- Monoplace:
  - Accommodates 1 supine patient
  - Technician outside the chamber for monitoring
  - Compressed with 100% oxygen
Multiplace:
- Holds multiple patients
- Holds attendants who “dive” with the patients
