Dry carbon dioxide baths (DCB / Reabox)
Dry Carbon Dioxide Bath Therapy (Reabox)
Industry clinical and economic procedure passport. Full biological mechanism (MoA), patient preparation protocol, first-choice equipment fleet, integration into the resort's master treatment rooms and market price benchmarks.
Clinical profile
Exposure of the skin to carbon dioxide, either in a water bath or in a "dry" gas bath without water. CO₂ dilates blood vessels and enhances skin microcirculation; traditional indications are chronic circulatory disorders. There are few large modern RCTs: the evidence consists of older reviews, physiological studies and isolated Russian RCTs within combined treatment.
Every statement links to a publication in the list below. This is a snapshot of published research, not a final assessment of the method: international practice and integrated protocols often run ahead of official publications. Draft based on published research; requires review by a physician. Revision: 2026-10-17.
Mechanism of action
Where studies show an effect
- Traditionally, chronic circulatory disorders in atherosclerosis: peripheral arterial occlusive disease of the legs, trophic ulcers, microangiopathies, mild hypertension; there is evidence of benefit in rehabilitation after myocardial infarction and stroke and in chronic venous insufficiency. [1]
- Post-thrombotic syndrome: dry carbon dioxide baths as part of a combination with laser and pulsed magnetic therapy (RCT). [4]
Open questions and study limitations
- The main review of indications was published in 1994; there are no current systematic reviews or large RCTs on carbon dioxide baths. [1]
- In the Russian RCT, dry baths were used only as part of a combined programme, so their own contribution was not isolated. [4]
- A related method, subcutaneous CO₂ insufflation, could not be assessed by a systematic review owing to the small number and low quality of studies. [5]
Safety
- The publications found report no safety data; in rats, prolonged CO₂ baths altered keratinocyte protein expression without changing capillary density. [6]

Evidence base
There is a physiological rationale and isolated RCTs within combined treatment; there are no up-to-date systematic reviews.

Publications were found in PubMed; titles and journals are given verbatim, conclusions are a brief summary of the abstracts under the conditions of the specific studies. The level shows the volume of published data, not the value of the method: A — Plenty of data: consistent systematic reviews and meta-analyses of RCTs; B — Some data: reviews or several RCTs, results are heterogeneous; C — Little data: single RCTs or controlled studies; D — Scarce data: mainly reviews, observational and experimental studies. The passport is updated as new work is published and with regard to international practice.
