Expanded Information
The so-called hypoxic state is a condition in which patients with respiratory diseases have impaired lung function and decreased ability to combine oxygen with air, resulting in an inability to provide enough oxygen to the body's internal organs, which is referred to as hypoxia. Patients with chronic obstructive pulmonary disease (COPD), for example, may be in a hypoxic state.
Doctors generally recommend that patients with chronic obstructive pulmonary disease (COPD) have their venous blood tested for hypoxia, and if hypoxia exists, they may recommend purchasing a home oxygen concentrator as an adjunct to treatment. But even if you need to use an oxygen concentrator, it is only recommended that you inhale oxygen for about 10 hours a day. Therefore, consumers should buy and use it under the guidance of a doctor, and should not buy and use it blindly.
