Oxygen is indispensable for human beings, and the atmospheric standard oxygen concentration is 20.9%. However, with the deteriorating air quality, the indoor and outdoor environments where human beings live will always be lower than this value, which poses a certain threat to human health. threat. When the oxygen concentration is between 19% and 20%, people tend to feel bored because incomplete combustion will increase the carbon monoxide in the air; when the oxygen concentration is lower than 18%, the elderly are in danger. Especially for the elderly with respiratory diseases, after a fall, the oxygen demand for shortness of breath increases instantaneously. If a certain amount of oxygen can be given in time at this time, the discomfort of the elderly will be relieved and precious time for rescue will be won.
