Basic knowledge about oxygen therapy:
To survive, we need to breathe in oxygen to go into our lungs, and then the oxygen will pass to the bloodstream in our bodies. However, in some cases, the amount of oxygen circulating in our blood can fall far below normal levels. For example, the flu, lung cancer, COPD (chronic obstructive pulmonary disease), and asthma are common heath issues that can cause oxygen levels to drop sharply. Specifically, when our blood oxygen levels drop below 60 mm Hg, that is considered too low and indicates the need for oxygen therapy; using oxygen therapy means inhaling extra oxygen from some form of oxygen-conserving container. Surely, this kind of device needs to be prescribed by a doctor.
A lot of doctors choose to prescribe an oxygen concentrator (also known as oxygen generator) for their respiratory patients. Currently, thanks to the evolution of medical technology, oxygen concentrators are no longer only used in hospitals. More and more people start to use oxygen concentrators at home. Oxygen concentrators have already become a necessary item of home medical devices to support people’s daily oxygen needs.
