DEDAKJ oxygen concentrator
At present, many families have prepared oxygen concentrators, especially those with "hypoxia". At the turn of autumn and winter, people with "chest tightness, shortness of breath, chronic bronchitis and lung diseases" began to use oxygen concentrators to inhale oxygen.
How to adjust the flow when using an oxygen concentrator? How to solve various problems such as abnormal machine sound and oxygen concentrator failure to produce oxygen? Even worried: "Will long-term oxygen inhalation cause oxygen dependence? How long do you need to inhale oxygen every day?" and many other questions.
DEDAKJ: A professional institution for terminal service brands of oxygen concentrators and ventilators, especially reprinting the popular knowledge of oxygen concentrators from the official website of the National Drug Administration Verification Center, a national authority, to share and popularize.
What are the common problems in the use of oxygen concentrators?
What are the common misunderstandings in home oxygen inhalation?
1. Is it normal for the oxygen concentrator to make a "puff...puff..." sound?
When the molecular sieve oxygen concentrator is working, there will be a regular "puff" sound (usually every 8 seconds or so). This is the sound of the normal molecular sieve switching.
2. During use, how much oxygen flow should be adjusted per minute?
The oxygen flow should be adjusted according to the doctor's advice. The oxygen flow rate will be different for different degrees of hypoxia. People who are taking oxygen therapy for chronic obstructive pulmonary disease should It is generally recommended to use it at low flow for a long time. Please follow the doctor's advice.
3. When the oxygen concentrator is in use, there are bubbles in the humidification cup. Why is there no oxygen in the oxygen tube?
Check whether there is leakage at the connection of the humidification cup and the oxygen tube, and check whether the vent of the humidification cup is blocked by scale.
4. When the oxygen concentrator is in use, the bottom temperature of the oxygen concentrator is particularly high. Can it still be used?
The compressor of the molecular sieve oxygen concentrator will heat up when working, which is generally normal. It is recommended to place the oxygen concentrator in a ventilated place when using it, and it is strictly forbidden to cover it.
5. Use of oxygen concentrator After a period of time, I found that the air flow has become smaller. What's going on?
Check the oxygen concentrator air intake filter device, clean the first-level filter or replace the second-level filter when necessary, and clean the internal pipeline of the humidifier cup to prevent scale clogging. DEDAKJ oxygen concentrator filter is recommended to be replaced with a new one every 2-4 months. Please contact the manufacturer for replacement.
6. How to know the oxygen concentration after the oxygen concentrator has been used for a period of time?
Professional oxygen concentrators generally have oxygen concentration indicators and low oxygen concentration alarm functions. If necessary, you can choose a professional oxygen concentrator sales service provider to detect and check the various indicators of the oxygen concentrator!
7. Can the oxygen concentrator continue to be used if there is an abnormal sound or abnormal alarm?
If the oxygen concentrator makes an abnormal sound or an abnormal alarm sound, it is recommended to stop using it and contact the DEDAKJ sales service provider for timely inspection or repair.
8. Is it normal that the noise of the oxygen concentrator has become louder after a few years of use?
Molecular sieve oxygen concentrators generally rely on compressors to compress air. After long-term use, the compressor leather bowl will wear and the noise will gradually increase. This is generally a normal phenomenon .
What are the common misunderstandings about home oxygen inhalation?
Misunderstanding 1: Anyone can inhale oxygen, which can not only treat diseases but also provide health care
1. Oxygen therapy is a highly professional treatment method. Oxygen concentrators are Class II medical devices. In addition to being used by medical institutions, small oxygen concentrators can be used for home auxiliary treatment under environmental and pathological hypoxic conditions, such as plateau hypoxia, severe respiratory diseases and cardiovascular and cerebrovascular diseases, but home auxiliary treatment oxygen concentrators must not be used for life support or life guarantee.
This product must be used under the guidance of a doctor and in accordance with the daily use time and flow rate to reduce the risk of improper indication selection. There is currently no evidence that oxygen inhalation has a health-care effect on normal people. On the contrary, improper oxygen inhalation may cause harm to the human body.
Misunderstanding 2: Long-term oxygen inhalation will lead to oxygen dependence or addiction
2. Human survival requires the inhalation of oxygen in the air through breathing activities. Under normal circumstances, the oxygen in the air can meet the needs of the human body. When the human body cannot fully inhale; the oxygen content in the air is insufficient, the process of oxygen entering the blood is blocked; when the ability of human cells to use oxygen in the blood decreases, hypoxia will occur.
Hypoxia refers to a series of pathological changes caused by insufficient oxygen supply or oxygen utilization disorder in human tissues, which causes changes in the body's functional metabolism and even morphological structure.
Long-term oxygen inhalation is to supplement the oxygen necessary for the human body due to hypoxia caused by related diseases. Healthy people in normal conditions, breathing air naturally, will not become dependent on or addicted to oxygen.
Myth 3: Long-term oxygen inhalation will cause oxygen poisoning
3. Oxygen poisoning refers to the pathological changes in the function and structure of certain systems or organs after the body inhales high-concentration oxygen above a certain pressure for a certain period of time.
The output oxygen concentration of a general oxygen generator is 93±3%, but it is not the oxygen concentration inhaled into the alveoli. When using a standard oxygen generator with a π-type oxygen inhalation tube, the inhaled oxygen concentration is related to the flow adjustment, that is: inhaled oxygen concentration = 21+(4x flow rate). Therefore, when inhaling oxygen for a long time, you must follow the doctor's advice to adjust the oxygen flow and the daily oxygen inhalation time. Incorrect oxygen inhalation methods may cause side effects or oxygen poisoning caused by oxygen inhalation.
Myth 4: Oxygen inhalation can be adjusted at will regardless of the condition, and the oxygen flow and time can be adjusted at will
4. Oxygen inhalation, also known as oxygen therapy or oxygen therapy, is to provide oxygen through an oxygen source that meets the medical oxygen standard, increase the arterial oxygen partial pressure (PaO:) and arterial oxygen saturation (Sa0), increase the arterial oxygen content (Ca0,), correct the hypoxia caused by various reasons, and promote tissue metabolism. It is a highly professional treatment method.
Therefore, oxygen inhalation needs to follow the doctor's advice, and scientifically adjust the oxygen flow and oxygen inhalation time according to the hypoxia indication arterial oxygen partial pressure or blood oxygen saturation.
Myth 5: As long as it is an oxygen concentrator, it can be used for oxygen therapy
5. Oxygen concentrators that can be used for home oxygen therapy, 1 liter -3 liter home oxygen concentrators have health care and medical effects, and are only used by people with non-serious respiratory diseases, such as students, pregnant women, the elderly, and white-collar workers. 5 Liter-20 Liter oxygen concentrators have significant medical effects and are suitable for patients with respiratory diseases, lung diseases, and special needs for oxygen inhalation and oxygen therapy. At the same time, a high-pressure oxygen machine of 20L or above can be used with a hyperbaric oxygen therapy chamber, which is very convenient for performing hyperbaric oxygen therapy at home.
