In most medical scenarios, oxygen concentrators often exist as the "life pillar" of patients. For patients with respiratory diseases, such as chronic obstructive pulmonary disease and asthma, oxygen concentrators can provide continuous and stable high-concentration oxygen, relieve breathing difficulties and relieve pain.

Now, oxygen concentrators are no longer professional equipment limited to medical use. They are gradually entering the lives of more people and playing an unexpected role.

Daily use of elderly people with diseases

For elderly people with chronic cardiopulmonary diseases, oxygen concentrators can relieve symptoms such as chest tightness and shortness of breath in daily life. Oxygen inhalation according to the doctor's recommended oxygen inhalation time and flow rate can improve the quality of life of the elderly, and can also allow the elderly to receive treatment and rehabilitation in a familiar environment, reduce psychological pressure and reduce the number of hospitalizations. In the long run, it not only makes oxygen inhalation easier, but also saves a lot of medical expenses.

Healthy elderly people can also inhale oxygen for a short time to refresh their minds and relieve discomfort when they feel tired or the air quality is poor. For example, on haze days, when outdoor activities cannot be carried out, oxygen inhalation can make the body more comfortable.

Pregnant women

Pregnant women usually have an increased physical burden during pregnancy and an increased demand for oxygen. Using an oxygen concentrator to breathe oxygen can provide sufficient oxygen for the fetus, avoid hypoxia symptoms, promote fetal growth and development, improve fetal heart and brain function, and relieve discomfort in pregnant women.

However, pregnant women should breathe oxygen under the guidance of a doctor and avoid self-operation. For example, if pregnant women breathe oxygen for a long time and at a high flow rate, it may affect the development of the fetus. Therefore, pregnant women should strictly pay attention to the time, frequency and oxygen concentration of oxygen inhalation to avoid excessive intake. Regular prenatal screening can timely discover and solve problems in the fetal development process.

People who often engage in mental work

For people who work at desks for a long time and students who face heavy academic pressure, high-intensity work may cause brain hypoxia, fatigue, inattention, etc. Using an oxygen concentrator to breathe oxygen for a while can relieve fatigue, increase brain oxygen supply, and improve work efficiency. However, oxygen inhalation is not a panacea. The effect of oxygen inhalation is different for fatigue caused by different reasons.

Special circumstances

Dizziness, nausea, difficulty breathing and other discomfort symptoms may occur after family gatherings or when someone drinks. It is recommended to send the patient to the hospital for ECG monitoring in time, measure the blood oxygen saturation, and observe the level of blood oxygen saturation. If the blood oxygen saturation is above 95%, there is generally no problem. If the blood oxygen saturation is lower than 90%, you can consider giving nasal cannula oxygen or mask oxygen to relieve discomfort and prevent hypoxemia.

In addition, people who live in areas with poor air quality for a long time can also get purer oxygen through oxygen concentrators to reduce the harm of air pollution to the body.

Proper oxygen inhalation after exercise can help recovery. Because during high-intensity exercise, muscle tissue consumes a lot of oxygen, causing a certain degree of hypoxia in the body. Supplementing oxygen can help relieve fatigue after exercise and help the body recover faster. By inhaling oxygen, the body can quickly replenish enough oxygen, relieve fatigue symptoms, and improve physical sensations after exercise.

In addition, some athletes often need to quickly recover their physical strength and mental state in a short period of time to prepare for the next game or training. Supplementing oxygen can help athletes recover their normal heart rate, respiratory rate and blood pressure faster, thereby speeding up the body's recovery. After oxygen inhalation, the oxygen content in the body's blood increases, which helps promote metabolism and the recovery process.

However, oxygen supplementation is not suitable for everyone. For ordinary people, oxygen supplementation through normal breathing after exercise is sufficient to meet the body's needs. Therefore, before supplementing oxygen, please consult a professional doctor and make sure that the method and dosage of oxygen supplementation are suitable for your physical condition.

People traveling in high altitude areas

In high altitude areas, the body may experience hypoxia, leading to uncomfortable symptoms such as dizziness, fatigue, and weakness, and even causing serious problems such as altitude sickness. Inhaling oxygen can help improve this situation, provide sufficient oxygen supply, help the body adapt to the high altitude environment or restore normal oxygen levels.

It is recommended to carry a portable oxygen concentrator for plateau travel, which can provide oxygen at all times, so that you can enjoy the beauty of nature without worrying about running out of oxygen, and enjoy the joy of travel without worries.

How to choose an oxygen concentrator for medical and health care use

Whether it is for medical or health care purposes, choosing an oxygen concentrator requires a comprehensive consideration of many factors, among which the following should be focused on. We remind that oxygen therapy should be carried out under the guidance of a doctor. The appropriate oxygen concentration should be determined according to the individual's health status and condition to achieve the best treatment effect and minimize potential risks.

01 Clear use needs

• Medical needs: If you are a patient with respiratory diseases (such as chronic obstructive pulmonary disease, cor pulmonale, asthma, etc.), cardiovascular and cerebrovascular diseases, diabetes and other diseases, and need long-term oxygen therapy to improve your physical condition, then you should choose a medical-grade oxygen concentrator. Medical oxygen concentrators can provide stable high-concentration oxygen to meet the patient's treatment needs. For example, COPD patients breathe oxygen for a long time every day. It is recommended to choose a medical oxygen concentrator of 5 liters or more so that there is enough oxygen supply when the disease attacks or shortness of breath.

• Health care needs: If you are a healthy person or use an oxygen concentrator only for health purposes such as relieving fatigue, improving sleep quality, and enhancing immunity, then you can choose a health-care oxygen concentrator. Generally, an oxygen concentrator with an oxygen flow rate of 1-5 liters can meet the needs, and usually does not require too high oxygen concentration and flow.

02 Oxygen concentration

• Medical use: The oxygen concentration of a medical oxygen concentrator should be stable at more than 90%, which is the key to ensuring the treatment effect. When choosing, check the product's test report or instructions to ensure that its oxygen concentration meets the standard. Some high-quality oxygen concentrators, such as those using molecular sieve pressure swing adsorption technology, can provide high-concentration oxygen.

• Health use: The oxygen concentration requirement of health-care oxygen concentrators is relatively low, so when choosing, you should also pay attention to the relevant parameters of the product. You can consult a doctor for professional oxygen inhalation advice based on your personal situation.

03 Oxygen flow

• Medical use: For patients who need medical oxygen therapy, the demand for oxygen flow varies depending on the condition. Generally speaking, mild patients may require an oxygen flow of about 3 liters/minute, while moderate and severe patients require an oxygen concentrator with a flow of 5 liters/minute or higher. When choosing, it should be determined according to the doctor's advice and the patient's actual situation.

• Health use: The oxygen flow of health-care oxygen concentrators is usually between 1-5 liters/minute, which can be selected based on personal feelings and needs. If it is only used occasionally, a low-flow oxygen concentrator is sufficient; if it is used frequently, a product with a slightly higher flow rate can be selected.

How to maintain the oxygen concentrator when it is idle to extend its service life

If the oxygen concentrator needs to be idle for a long time, we can maintain it in the following ways to extend its service life.

First, place the oxygen concentrator in a dry and well-ventilated place. Avoid direct sunlight, humidity, heat sources and bright and dark fire sources, environments with too high/too low temperatures, severe pollution or smoky environments, etc. In addition, do not place debris and water and oil containers on the oxygen concentrator casing, and do not place any debris at the exhaust port.

Secondly, clean the casing and filter of the oxygen concentrator regularly to prevent dust and impurities from accumulating and affecting the oxygen production effect. Turn off the device and disconnect the AC or DC power supply before cleaning. When cleaning, avoid spraying water or detergent directly on the casing. Instead, use a moist (non-wet) fabric or sponge and spray a neutral detergent on the fabric or sponge to clean the casing and power adapter.

For the filter, you can clean or replace it according to the instructions. In addition, when the oxygen concentrator is not used for a long time, its power supply should be unplugged to avoid aging of the equipment due to long-term power supply.
