What Is Ozone Concentration?

Ozone concentration refers to the content of ozone in a unit volume. The mass ratio unit is mg / L, g / m3, and the volume ratio unit is 1%, 5%, etc. The health department often uses the ppm unit. These units are often used to indicate the ozone generator outlet concentration or atmospheric ozone concentration. The ozone concentration indicates the ability of the ozone preparation equipment to generate ozone, and refers to the sum of the weight of ozone in a unit volume. The larger the value, the faster the ozone preparation equipment generates ozone. Ozone is very unstable and will decompose on its own.

What is the safe concentration of ozone in medical applications? ^[2]

Medical ozone is often at different concentrations when it is generated. The amount of ozone is greater than the amount of medical pure oxygen at the inlet of the ozone generator. It is called the percentage concentration, and the unit is micrograms per milliliter (ug / ml). Under standard conditions, the mass of one liter of oxygen is 1.4 grams. Standard condition: Generally refers to the case where the temperature is 0 ° C (273.15K) and the pressure (or pressure) is 101.325 kPa (1 standard atmosphere, 760 mm Hg).

60ug / ml of ozone is considered to be the upper limit of the ozone blood treatment method. The use of ozone infusion of blood above 60 ug / ml may cause red blood cells to fold and cause hemolysis. Dr.sweet et al.'S experiments showed that ozone at concentrations above 72 ug / ml can inhibit the growth of healthy cells. If we keep the ozone concentration below 60ug / ml, there will be no problems with treatment such as ozone autotransfusion.
