Almost all living things need oxygen to survive, especially for humans. Humans need oxygen to live, and the minimum oxygen concentration in the air required for human breathing is 19.5 percent. The OSHA determined the optimal range of oxygen in the air for people runs between 19.5 and 23.5 percent. But what’s the minimum oxygen concentration for patients who need a medical oxygen generator?
The purity of bottled medical oxygen is ≥ 99.5%, and there’s no oxygen concentration specified for the medical oxygen generator. But relevant technical standards for oxygen production equipment are provided. Medical molecular sieve oxygen production equipment produce oxygen by molecular sieve variable pressure adsorption process, and oxygen concentration should be 90%~96% (VN). Generally speaking, no medical oxygen can be put into use in clinical treatment unless the oxygen concentration reaches 93%.
Patients will inhale air when using the medical oxygen generator, thus diluting the oxygen concentration. The oxygen concentration inhaled by the human body will also be reduced even if the medical oxygen generator is used due to the structure of the human body. The oxygen concentration must meet the minimum standard (93%) to ensure that patients can inhale sufficient oxygen concentration.
At present, medical oxygen generators with 93% oxygen concentration have mature technologies. As long as the product can be operated normally in use, it can ensure the basic oxygen requirements of patients and hospitals. But home or health care oxygen generator will have reduced oxygen concentrations due to unstrict production norms and standards, and it’s not a big deal if the medical oxygen generator is only used at home for the purpose of health care, instead of emergency. Select a professional oxygen generator or go to the hospital frequently for oxygen therapy if the patient needs strict oxygen therapy to treat oxygen deficiency.
