Understanding the Difference Between HBOT, MedHBOT, and mHBOT
Pressure is only one part of the picture. Equipment, oxygen delivery, installation, operator competence, procedures and ongoing support all shape the operating environment.
Hyperbaric equipment is not one single category. Solid O2 uses the terms HBOT, MedHBOT and mHBOT as an educational framework to explain practical differences without implying that a marketing term determines legal status.

HBOT – Hyperbaric Oxygen Therapy
HBOT is an established clinical term for hyperbaric oxygen therapy delivered under medical protocols. Clinical installations commonly operate around or above 2 ATA, although protocols, equipment and statutory definitions vary. Depending on the chamber design, oxygen may be delivered through a hood or mask, or the chamber may use an oxygen-rich environment.
Clinical HBOT is generally provided in hospitals or appropriately equipped medical facilities with qualified medical oversight and requirements applicable to the facility, equipment and intended use. Research findings from clinical HBOT should not automatically be applied to equipment operating at different pressures or using different oxygen-delivery methods.
mHBOT – mild Hyperbaric Oxygen Therapy
mHBOT is a term commonly used in product marketing for lower-pressure systems, often around 1.5 ATA or below. This is not a universal statutory boundary. Product design, oxygen delivery, monitoring, servicing, operator training and technical support can vary significantly.
Lower pressure, fabric construction or oxygen delivered through a mask does not automatically remove legal, safety or regulatory obligations. Each product and installation should be assessed according to its own verified specifications, intended use and operating environment.
MedHBOT – Medium Hyperbaric Oxygen Therapy
MedHBOT means Medium Hyperbaric Oxygen Therapy. Solid O2 uses the term for its controlled medium-pressure operating model, generally within approximately 1.3 ATA to 2.2 ATA and always subject to the manufacturer’s approved operating parameters and the verified limits of the specific equipment.
Solid O2-supported MedHBOT systems use filtered ambient air for chamber pressurisation and an oxygen concentrator to deliver concentrated oxygen to the occupant through a mask. MedHBOT is a distinct operating environment, but Solid O2 applies professional hyperbaric safety principles, structured operator training and documented competency standards appropriate to the equipment and treatment environment being used.
The framework incorporates relevant internationally recognised hyperbaric, human-occupancy, pressure-safety, oxygen-safety and operational principles where reasonably applicable to the specific MedHBOT equipment and environment.
Practical comparison
| Framework term | Pressure description | Oxygen delivery | Typical environment |
|---|---|---|---|
| HBOT | Clinical protocols commonly around or above 2 ATA; protocols vary | Medical oxygen according to the chamber and clinical protocol | Hospitals and appropriately equipped medical facilities |
| MedHBOT | Generally approximately 1.3 ATA to 2.2 ATA, subject to model specifications | Concentrated oxygen via mask; chamber pressurised with filtered ambient air | Solid O2-supported professional, SME and home installations |
| mHBOT | Often marketed around 1.5 ATA or below; not a universal statutory boundary | Varies by product and setup | Commonly home or wellness environments |
What Actually Makes a MedHBOT Site Professional?
A chamber is only one component. Professional status depends on three current, documented pillars.
1. Equipment evidence
The chamber system is identified by serial number, used within verified limits and supported by current installation, service, maintenance and repair records. Any HM certificate is recorded only as one item in the evidence pack; HM is not presented as a regulator.
2. Service status
The system is serviced at least annually or every 1,000 operating hours, whichever occurs first, unless the manufacturer requires a shorter interval. Overdue service changes the current status.
3. Operator coverage
Qualification belongs to the trained individual and is portable only while certification or recertification, revision training, equipment competence, site induction and authorised scope remain current.
Status can change
Equipment, operator and site records should use precise terms such as confirmed, under review, action required, expired, overdue or not verified. A prior assessment should never be presented as a permanent statement of legal compliance.
Safety and suitability
Sessions should follow the manufacturer’s instructions, Solid O2 procedures and appropriate client screening. Suitability differs between individuals. Medical questions and urgent or complex conditions should be referred to an appropriately qualified healthcare professional or hospital facility.
Summary
HBOT, MedHBOT and mHBOT describe different operating contexts within Solid O2’s educational framework, but the terms are not interchangeable and do not imply equivalent outcomes. Compare the chamber design, verified operating limits, oxygen-delivery method, intended use, installation, operator competence, servicing and support model – not only the label.
