This video transcript from Dr Gregory Weir's channel discusses the **potential risks and side effects associated with hyperbaric oxygen therapy (HBOT)**, primarily intended for his patients at Life Eugene Marais Hospital's Hyperbaric Unit. While HBOT is generally safe with minimal incidents, awareness of potential issues is crucial. A key risk is **fire** due to the 100% oxygen at high pressure; therefore, precautions like 100% cotton clothing and avoiding electronics are vital. **Ear pressure changes** are common, manageable through jaw protrusion, yawning, or gentle nose blowing. **Oxygen toxicity** to the brain (seizures in susceptible individuals) and lungs (shortness of breath, especially in asthmatics or smokers) are rare due to strict protocols but possible. **Blood glucose levels can drop**, especially in diabetics, necessitating pre-treatment meals and in-chamber sweets. Other potential side effects include **fatigue**, **changes in visual acuity** (particularly in those over 50 or with a family history of cataracts), **paresthesia**, increased sensitivity at surgical sites, and rarely, **claustrophobia**, mitigated by chamber design and communication. Open communication with the HBOT team is paramount for patient safety and addressing any concerns.

The potential risks, side effects, and complications of hyperbaric oxygen therapy are described to patients as informed consent before initiation of therapy.
