What is liquid nitrogen cryotherapy

After the development of the vacuum flask to store subzero liquid elements, such as nitrogen, oxygen and hydrogen the use of cryotherapy dramatically increased.

By the 1940’s , liquid nitrogen became more readily available , and the most common method of application was by means of a cotton applicator. In 1961 , Cooper and Lee introduced a closed-system apparatus to spray liquid nitrogen. In the late 1960’s , metal probes became available.

By 1995 Whole Body Cryotherapy became a standard procedure in Departments of Pulmonary Medicine in Russia.

Liquid nitrogen is the best and universal freezing source because of its low boiling point and its ease of use. Other sources that are used to freeze , such as Freon , carbon dioxide , and nitrous oxide, do exist, but they are not as efficient  because of their higher boiling points.

During procedure  1,5 kg  of liquid nitrogen ( 1 min procedure )  is used and  it takes 5 kg  to freeze  out  the Cryosauna (cabin startup).

The proper choice of equipment for cryotherapeutical treatment – is the main reason for good medical and commercial success. The temperature in cryosauna should be more than -130°C. Utilization experience shows, that this requirement is met only in cryosaunas using liquid nitrogen as a cooling source. The gas cooling before it’s supplying into the procedure cabin causes its saturation (enrichment) of nitrogen vapors, therefore the patient should be protected with different means against breathing such air. The most reliable and safe equipment for cryogenic treatment is cryosauna KRION, where patient is immersed in cryogenic gas up to the shoulders. The area above the cabin is ventilated, so the patient breathes pure air. The cabin has elevator for low height patients.
