mHBOT vs HBOT: What’s the Difference Between Mild and Clinical Hyperbaric Oxygen?
What Is HBOT (Clinical Hyperbaric Oxygen Therapy)?
HBOT (Hyperbaric Oxygen Therapy) refers to clinical-grade hyperbaric treatment as defined by the Undersea and Hyperbaric Medical Society (UHMS).（HBOT）
According to UHMS, HBOT is an intervention in which an individual:
-
Breathes near-100% medical-grade oxygen (≥99%)
-
Inside a hyperbaric chamber
-
At a pressure of ≥1.4 ATA
-
Typically using an oxygen mask or hood
HBOT systems are usually:
-
Installed in hospitals or medical facilities
-
Classified as medical devices
-
Used under physician supervision
-
Applied for approved clinical indications
Because of these requirements, HBOT is subject to strict medical regulations, certifications, and clinical oversight.
What Is mHBOT (Mild Hyperbaric Oxygen Therapy)?
mHBOT (Mild Hyperbaric Oxygen Therapy) refers to low-pressure hyperbaric systems designed for wellness, recovery, and performance support, rather than clinical treatment.
Typical characteristics of mHBOT include:
-
Operating pressure between 1.3–1.5 ATA
-
Use of oxygen-enriched air inside the chamber (not 100% oxygen)
-
Whole-chamber pressurization
-
Non-medical classification in most markets
mHBOT systems are commonly used in:
-
Wellness centers
-
Sports recovery facilities
-
Longevity and performance studios
-
Home or commercial non-medical settings
Importantly, mHBOT does not meet the UHMS definition of clinical HBOT, because it does not deliver near-100% medical oxygen via mask at pressure.
Key Differences Between mHBOT and HBOT
| Feature | mHBOT | HBOT |
|---|---|---|
| Pressure | 1.3–1.5 ATA | ≥1.4 ATA |
| Oxygen Delivery | Oxygen-enriched air | ≥99% medical oxygen |
| Oxygen Method | Whole-chamber | Mask / hood |
| Regulatory Status | Non-medical (wellness) | Medical device |
| Typical Locations | Wellness, recovery centers | Hospitals, clinics |
| Intended Use | Wellness & recovery support | Clinical treatment |
Why the Difference Matters
Understanding the distinction between mHBOT and HBOT is critical for:
-
User safety
-
Regulatory compliance
-
Accurate product positioning
-
Long-term business sustainability
Marketing an mHBOT system as “medical-grade HBOT” may expose manufacturers and distributors to regulatory, legal, and commercial risks, especially in Europe, North America, and the Middle East.
Choosing the Right System
-
HBOT is appropriate for licensed medical environments requiring clinical oxygen delivery under medical supervision.
-
mHBOT is ideal for users seeking pressurized oxygen-enriched environments for wellness, recovery, relaxation, and performance support—without medical claims.
Many customers prefer mHBOT due to:
-
Lower operating costs
-
Easier installation
-
Broader accessibility
-
Fewer regulatory barriers
Final Thoughts
mHBOT and HBOT are related technologies, but they serve different purposes and follow different standards.
A transparent, compliant explanation builds trust with clients, partners, and regulators—and ensures sustainable growth in the global hyperbaric market.
