| In the public consciousness: the atmosphere of oxygen is an inexhaustible resource, "hypoxia" is unfounded doubts style, real life people are less likely to encounter hypoxic damage!
The Chinese Geophysical Society Advisory Committee of forecasting natural disasters Professor Chen Yiwen said: "oxygen depletion" is the reality of human harm that has actually occurred, not the possible future risk!
Earth's atmosphere, "oxygen depletion" does not mean global consumption of oxygen containing atmosphere has done, but to population density, the burning of fossil fuels economically developed areas, and the vast majority of people live, work areas, due to excessive consumption of oxygen these areas in other parts of oxygen for long periods to get timely and effective supplement oxygen, resulting in lower space, the atmosphere in these areas long-term oxygen content close to or below the 19.5% level, these areas of serious damage to human health caused by long-term atmospheric oxygen conditions ! For example: Every year some 60 million Chinese died of lung cancer, lung cancer death rate has become China's first malignant tumor! Young people the incidence of coronary heart disease increased by 150% than the original! Many cities in China in recent years, large numbers "chronic laryngitis"! These are all with all that oxygen depletion, air pollution, lack of oxygen, in particular to people living in the modern city with air conditioning hypoxia is more severe.
Elderly due to degradation of the body, especially the lungs, respiratory function, reduced ability to transport blood the heart, so that elderly patients with chronic hypoxia, metabolism slows lead to premature aging, especially those who suffer from cardiovascular disease or respiratory diseases, due to oxygen exchange channels and transport channels have undergone barriers, lack of oxygen is even more obvious, more serious.Oxygen concentrators can generate 30% pure oxygen.It is a good choice for modern people.
Hypoxia is not far away from us, just you by my side. In this regard, numerous experts urge: Do not ignore the elderly population in the body of hypoxia-related symptoms and signals!Oxygen concentrator,portable oxygen concentrators are invented to meet the demands for the hypoxia.
Oxygenating the horn is sounded, the middle-aged science supplemental oxygen can not wait!
