Mild Hyperbaric Oxygen Therapy (mHBOT)
Mild hyperbaric oxygen therapy, or mHBOT, refers to hyperbaric sessions conducted at lower pressures, generally from 1.3 to 2.0 ATA. Users sit or recline inside a sealed chamber that is pressurized above normal atmospheric pressure while breathing supplemental oxygen. OxyEdge manufactures hard-shell mHBOT chambers in the USA for wellness centers and homes, operating within this mild pressure range.
Key Facts
- mHBOT generally refers to pressures from 1.3 to 2.0 ATA.
- Sessions take place inside a sealed, pressurized chamber.
- OxyEdge hard-shell chambers operate within the mild hyperbaric range.
- Oxygen is supplied by a medical-grade concentrator during the session.
- OxyEdge chambers are intended for wellness use, not medical treatment claims.
- Available in single-person, two-person, and walk-in formats.
What is mild hyperbaric oxygen therapy?
Mild hyperbaric oxygen therapy is a session performed inside a chamber pressurized to a lower range than clinical high-pressure hyperbaric systems. The user breathes supplemental oxygen while the ambient pressure is elevated.
The mild in mHBOT refers to the operating pressure. Most mild systems operate between 1.3 and 2.0 ATA.
What pressures are used in mHBOT?
Pressure is commonly expressed in ATA, or atmospheres absolute. The table below shows how common mild pressures compare to sea-level pressure.
How is oxygen delivered during a session?
During an OxyEdge session, a medical-grade oxygen concentrator supplies oxygen to the user through a mask or open-flow system while the chamber is pressurized with ambient air.
This combination of elevated pressure and supplemental oxygen defines the mHBOT experience.
How does mHBOT differ from clinical hyperbaric therapy?
Clinical hyperbaric oxygen therapy is typically delivered at higher pressures in medical facilities under professional supervision. Mild hyperbaric therapy uses lower pressures and is used in wellness settings.
OxyEdge chambers are wellness products. OxyEdge does not make medical treatment claims about its chambers.
Frequently Asked Questions
What does mHBOT stand for?
mHBOT stands for mild hyperbaric oxygen therapy, referring to hyperbaric sessions performed at lower pressures, generally 1.3 to 2.0 ATA.
What pressure is considered mild?
Mild hyperbaric pressures generally fall between 1.3 and 2.0 ATA. OxyEdge hard-shell chambers operate within this range.
Is mHBOT the same as clinical hyperbaric therapy?
No. Clinical hyperbaric therapy uses higher pressures in medical settings, while mild hyperbaric therapy uses lower pressures in wellness settings.
How is oxygen supplied in an OxyEdge chamber?
A medical-grade oxygen concentrator supplies oxygen through a mask or open-flow system while the chamber is pressurized with ambient air.
