Medical CAT® CO₂ therapy
Medical CAT®-CO₂ therapy is a physical treatment procedure in which medical carbon dioxide (CO₂) is absorbed through the skin in a controlled manner. For this purpose, the body - with the exception of the head and shoulders - is embedded in a special treatment cover.
Carbon dioxide is converted into bicarbonate in the tissue. This causes a slight change in the pH value locally. This natural process supports the so-called Bohr effect. Oxygen can be delivered more easily from the blood to the tissue, which can support microcirculation and oxygen supply to the tissue.
The treatment takes place in a relaxed position while lying down, is non-invasive and has been used for many years in, among other things, vascular medicine, rehabilitation and wound care. Studies and reviews describe possible effects on blood flow, tissue oxygenation and wound healing; At the same time, it is emphasized that further research is required to classify the effectiveness and the optimal areas of application.
At Beyond Med, CAT®-CO₂ therapy is therefore only used after medical assessment as a possible component of a prevention, regeneration or therapy concept.

Medically assessed. Non-invasive. Calmly lying down.
Sequence
How does the treatment work?
During the treatment you will lie comfortably on a treatment table. The body is placed in a special treatment cover up to below the shoulders. The head and shoulders remain outside of the treatment and do not come into contact with the carbon dioxide.
After the cover has been put on, a light vacuum is first created. Medical CO₂ is then introduced in a controlled manner. The treatment takes about 30 minutes and is usually well tolerated.



Application
Applications studied
Microcirculation
Studies examined effects on skin blood flow and tissue oxygen supply [1, 2].
Circulatory disorders of the legs
Use in intermittent claudication (peripheral arterial disease) has been studied [3].
Wound healing disorders
Complementary use in impaired wound healing has been studied [4].
Limits of the evidence
For other applications the data are insufficient. Whether an application makes sense is decided medically on a case-by-case basis.
background
Why CO₂ instead of oxygen?
CAT® CO₂ therapy uses a natural physiological mechanism of the body. Absorption of carbon dioxide through the skin supports the so-called Bohr effect. This facilitates the release of oxygen from the blood to the tissue and can thereby improve the oxygen supply to the cells [1].
The assumed mechanism is therefore not based on additional oxygen but on better use of the oxygen already present in the tissue [1].
Advantages
Benefits of CAT® CO₂ therapy
- Non-invasive physical therapy procedure
- Relaxed application while lying down
- Studied with regard to tissue blood flow
- Used for years in balneology and vascular medicine, among others; the evidence is limited
series
Possible course of treatment
We determine the number of sessions individually. Depending on the medical question, a course of treatment may for example include:
- about 12 applications
- 1-2 applications per week
- approx. 30 minutes per treatment
The exact number of applications depends on the individual therapy goal and is determined as part of the medical consultation.
Important NOTE: CAT®-CO₂ therapy is a complementary medical procedure. Statements about possible areas of application are based on current scientific knowledge and many years of clinical experience. Whether treatment makes sense will be decided after an individual medical examination. A specific treatment success cannot be guaranteed. The therapy neither replaces necessary diagnostics nor guideline-based treatment of existing diseases.
