The word "oxygen" is often associated with serious health problems. Does oxygen mean that there is a serious problem with the body? Does oxygen create dependence? What to look out for? Hear what the experts have to say.
01
When is oxygen necessary?
In film and television works, there are often scenes of patients taking oxygen, and under this subtle influence, it is often easy for people to associate oxygen inhalation with critical illness. In fact, oxygen inhalation can not only assist in the treatment of some respiratory diseases, but also provide daily health care for sub-healthy people.
In medicine, oxygen inhalation is mainly used to relieve dyspnea, as well as dizziness, palpitation, chest tightness, breathlessness and other symptoms caused by hypoxia. Ye Huan, director of the Department of Respiratory and Critical Care Medicine at Beijing Chest Hospital, said that when the partial pressure of oxygen is less than 60 mm Hg or the pulse oximetry is less than 90%, home oxygen therapy should be performed.
❖ Does regular oxygen supply cause dependence?
No. Oxygen is necessary for the human body to function at all times. Oxygen inhalation is to improve the body's oxygen supply, and if the hypoxia condition is improved, oxygen inhalation can be stopped, and there will be no dependence.
02
Oxygen concentrators and ventilators
What's the difference?
An oxygen concentrator is a device that produces oxygen, which can produce a standard concentration of oxygen for human use, and is mainly used for adjuvant treatment or daily health care when people have hypoxic conditions for various reasons. A ventilator is a breathing aid and does not provide additional oxygen on its own.
In some special cases, it is sometimes necessary to use an oxygen concentrator in conjunction with a ventilator. According to Director Ye Huan, patients with nocturnal obstructive sleep apnea, when the lesion occurs, the oxygen saturation may only be more than 20%, for such patients, they are often assisted by non-invasive ventilators, and combined with oxygen generators to supplement oxygen, so as to improve the severe hypoxemia of patients during sleep.
03
What are the 5 points to pay attention to when taking oxygen at home?
01
Choose the right oxygen flow rate
The 1~2 liter oxygen concentrator is a household health care oxygen concentrator, which is mostly suitable for pregnant women, white-collar workers, students and other sub-healthy people and long-term mental workers. Oxygen concentrators of 3 liters and above are mostly suitable for the health care of the elderly or the adjuvant treatment of people with respiratory diseases, cardiovascular and cerebrovascular diseases, etc. You need to choose the right one according to the doctor's advice.
02
Pay attention to whether the oxygen concentration meets the standard
According to the requirements of the General Technical Specification for Medical Molecular Sieve Oxygen Production Equipment, the oxygen produced by the molecular sieve pressure swing adsorption process using air as raw material has an oxygen concentration of 90%~96% (VI).
If the oxygen concentration fluctuates widely or falls below 90% for a long time, it will not only be uncomfortable, but may also cause ineffective oxygen inhalation. If it is found that the oxygen concentration output by the oxygen concentrator is lower than the specified at home, it must be stopped immediately for inspection, and the molecular sieve and other accessories must be cleaned or replaced in time.
03
Focus on the continuous oxygen supply capacity of the oxygen concentrator
In general, oxygen therapy for health care purposes can be done within half an hour each time. However, for special groups who need oxygen concentrators to cooperate with disease adjuvant treatment or have severe respiratory diseases that require the use of oxygen concentrators, long-term continuous oxygen therapy is often required. It is also important to choose an oxygen concentrator that can provide stable oxygen supply for a long time.
04
Choose an oxygen concentrator that runs quietly
A quiet environment is more conducive to the treatment and recovery of the sick or recovered person. Therefore, making the operation sound of the oxygen concentrator smaller is also a problem that the industry has been overcoming, such as Haier, in response to this problem, has developed the "Zhichun Jing" light sound oxygen production system, through multi-dimensional noise reduction technology, so that the oxygen concentrator can achieve a lighter operation.
05
Do a good job of cleaning and disinfection
The humidification bottle and humidification water tank of the oxygen concentrator need to be cleaned every day and the humidified water should be replaced to avoid bacterial infection.
Nasal cannulas or masks need to be washed daily and replaced every half a month or a month. Clean or replace the air filter once a month, replace the gas pipeline every two months, regularly maintain the equipment and supporting devices every year, and replace it in a timely manner according to the condition of each fitting.
