Ozone treatment gas is produced in hospitals using medical-grade oxygen sources. The gas is extremely effective at eradicating bacteria, viruses, and other pathogens from hospital equipment such as suction tubes and IV needles. Ozone therapy uses low concentrations of ozone gas to cleanse and heal various parts of the body. The gas is commonly applied through a device called an ozonator. There are two main types of ozonators: continuous flow and pulsed. With both types of devices, you will need to purchase an ozonation cartridge that can be inserted into the machine during use. These can usually be replaced when they become depleted. Continuous-flow machines produce a constant stream of ozone, while pulsed-output machines release the gas intermittently. There are several different methods for utilizing ozone therapy to treat illnesses. One method involves injecting ozone directly into sore areas of the body, such as joint spaces or wounds. This procedure is called arthrosonomy. Ozone injected this way has been shown to relieve pain and inflammation associated with osteoarthritis and other joint problems. Another method is to expose patients to ozone inhalation. Patients are given special masks designed for this purpose.
