Hyperbaric Oxygen Therapy Explained: Healing, Performance, and Wellness, Part 1

Hyperbaric Oxygen Therapy (HBOT): Beyond the Bends—Wounds, Stroke Recovery, Radiation Injury, and Performance. Nicole Garrett, founder and COO of Under Pressure Hyperbarics, details hyperbaric oxygen therapy (HBOT). She explains how HBOT treats divers’ decompression sickness by recompressing nitrogen bubbles and reducing inflammation, and how therapeutic benefits depend on reaching adequate pressure (commonly around 2.0 atmospheres or more; diver treatment may begin at 2.8). Garrett describes HBOT’s history, FDA-approved uses such as diabetic wound healing, radiation injury, and sudden sensorineural hearing loss (often combined with steroids), and off-label use for stroke/TBI recovery, cognitive issues, autoimmune flares, Crohn’s disease, athletic recovery, anti-aging research (including telomere findings), and adjunctive cancer care. She contrasts “soft” chambers with higher-pressure medical chambers, discusses treatment courses (often 10–60 sessions), safety and contraindications (ears, pneumothorax, retinal bubble procedures), and practical barriers like cost, insurance coverage, and facility/oxygen regulations.
