How Hyperbaric Oxygen Therapy Works
It's not just about breathing oxygen. It's about how your body uses it.
During Hyperbaric Oxygen Therapy, increased atmospheric pressure allows significantly more oxygen to dissolve into your blood plasma. This additional oxygen is then transported throughout the body, supporting the natural biological processes involved in healing, recovery, performance and overall wellbeing.
THE SCIENCE

You relax in the chamber
Pressure increases
Oxygen dissolves into plasma
Delivered throughout body
More than just
breathing oxygen
Under normal conditions, almost all of the oxygen you breathe is transported by haemoglobin within your red blood cells, leaving very little dissolved directly in the blood plasma. During Hyperbaric Oxygen Therapy, increased atmospheric pressure allows significantly more oxygen to dissolve into the plasma itself.
Because plasma circulates throughout the entire body, this additional dissolved oxygen can be delivered beyond the normal oxygen-carrying capacity of haemoglobin, supporting the body's natural processes involved in healing, recovery and cellular function.
DID YOU KNOW?
Your red blood cells are already carrying almost as much oxygen as they can under normal conditions. The unique benefit of HBOT comes from increasing the amount of oxygen dissolved directly into your blood plasma.
WHAT HAPPENS DURING A SESSION?

Pressurisation
The chamber is gradually pressurised while you relax comfortably.
Plasma Oxygenation

More oxygen dissolves into your plasma and circulates throughout the body.

Cellular Response
Cells receive increased oxygen availability to support normal metabolic activity.

Recovery
The body begins responding both during and after your session.
Every session is supervised by our trained team, ensuring your safety, comfort and a personalised treatment experience from start to finish.
WHAT HAPPENS OVER TIME?
Some physiological effects occur during every session, while others develop gradually through repeated exposure over time.

DID YOU KNOW?
Research suggests some of the biological effects associated with HBOT continue developing after you leave the chamber, which is why consistency is often considered just as important as any individual session.
WHY PRESSURE MATTERS
Personalised pressure.
Personalised results.
Hyperbaric Oxygen Therapy is not a one-size-fits-all treatment. Different treatment pressures may support different physiological responses, which is why treatment recommendations should always be guided by both the available evidence and the individual.
At Renume, we consider your goals, medical history, comfort and the relevant treatment protocols when recommending pressure and session frequency.
The most appropriate pressure isn't always the highest. It's the one that's right for you.

As treatment pressure increases, so does the amount of oxygen dissolved into the blood plasma. However, HBOT isn't simply a case of "more is better". Different treatment pressures are associated with different physiological responses, which is why a range of evidence-based treatment protocols exist.

Brain & Nervous System
Supports cognitive function, mood, and neurological recovery.
Circulation
Promotes healthy blood flow and support vascular function.
Oxygen Delivery
Enhances oxygen transport to tissues throughout the body.
Bones & Soft Tissue
Supports tissue repair, wound healing, and bone health.
Muscles & Connective Tissue
Aids recovery from exercise, injury, and inflammation.
Immune Function
Supports immune regulation and overall resilience.
EVIDENCE-LED CARE
Backed by science. Focused on you.
Hyperbaric Oxygen Therapy continues to be researched across areas including recovery, wound healing, neurological health, sports performance, and healthy ageing.
While research is growing, treatment protocols should always be based on current evidence and your individual circumstances.
* HBOT is intended to support health, recovery and wellbeing. It is not a replacement for medical care, and suitability depends on your individual health, goals and medical history.
