HBOTLAB

  Every HBOT chamber is a pressure vessel for human occupancy. That is not a wellness industry phrase — it is an engineering classification that carries legal, structural, and safety obligations that every Indian patient deserves to understand.   Pressure vessel for human occupancy (PVHO): Any enclosed structure designed to be occupied by one or more persons at a pressure significantly above or below normal atmospheric levels. Every hyperbaric oxygen therapy chamber — hard or soft, hospital or wellness centre — is a PVHO. Governed internationally by ASME PVHO-1 engineering standards.     In 2025, two people died inside HBOT chambers in the United States. One was a five-year-old child. Four facility staff face second-degree murder charges. The US Food and Drug Administration issued a national safety letter. And India — where no regulation currently mandates PVHO certification — had already seen a chamber rupture with a patient inside in September 2024. This article ex...

  Radiation therapy saves lives. It also destroys the tissue in its path — permanently damaging blood vessels, creating lifelong hypoxia, and leaving survivors with complications that standard medicine has no mechanism to address. HBOT has that mechanism. hyperbaric oxygen therapy and cancer — radiation injury survivors HBOT tissue repair angiogenesis Hyperbaric oxygen therapy and cancer survivor care occupy the same clinical space for one reason: radiation permanently destroys the blood supply of the tissue it treats. Cancer cells die. The treatment works. But the radiation that kills tumour cells does not spare the healthy tissue in the radiation field. Blood vessels thicken and narrow. Capillaries are obliterated. The tissue that remains — the tissue the patient will live in for decades after remission — becomes chronically hypoxic, poorly healed, and incapable of responding to further treatment or surgical intervention. This is late radiation injury. It is not a complication of...
