Medical argon is used in cryotherapy to destroy diseased cells. In addition, cryosurgical needles are cooled with the gas and it is used as a resonance gas in laser devices.
Medical helium is used in cryotherapy for the ablation of tumors. In this process, tissue affected by cancer, preferably in the liver, kidneys, prostate and breast, is destroyed by extreme cold.
Medical carbon dioxide is suitable for endoscopy applications in minimally invasive surgery to “inflate” body cavities in order to create a better overview and accessibility. Liquid carbon dioxide, similar to medical nitrogen, is also used as an icing agent or coolant.
Medical carbon dioxide is also used in in-vitro fertilization (IVF) to create a body-like environment in incubators. This supports the optimal development of embryos outside the body.
Medical nitrogen is used as deep-frozen liquid nitrogen at temperatures below -190°C. It is used, for example, in cryotherapy. It is used in cryotherapy, for example to freeze warts, scar tissue or precursors of skin cancer. Medical nitrogen is also used to preserve biological samples and materials.
