Chambers raise air pressure to 1.5–3× normal levels, letting oxygen dissolve into blood plasma—not just red blood cells.
HBOT is a medical treatment where a patient breathes 100% pure oxygen in a pressurized chamber at pressures higher than normal atmospheric pressure (usually 2 to 3 atmospheres absolute, ATA). This increases the amount of oxygen dissolved in the blood plasma, significantly enhancing oxygen delivery to tissues, especially those with poor circulation or hypoxia (low oxygen) due to injury or disease

-
Expertise: Wound care, lymphedema, diving medicine, and hyperbaric oxygen therapy.
-
Opinion: Dr. Guilliod emphasizes that HBOT provides a "hyperoxigenated" environment that improves oxygen supply to hypoxic tissues, aids wound healing, and supports clinical management of various pathological processes. His center holds a Level 1 Accreditation with Distinction from the Undersea and Hyperbaric Medicine Society (UHMS), reflecting the highest standards of care and safety
-
Credentials: Board-certified internist with expertise in geriatric medicine and palliative care.
-
Contribution: Authored a review on hypoxia and HBOT explaining the physiological basis of HBOT, highlighting how increased oxygen under pressure changes cellular function and tissue repair mechanisms. He notes that HBOT can induce permanent beneficial changes in tissue structure and function after multiple treatments
