Oxygen Concentrator Buying Guide
Oxygen concentrator is divided into medical oxygen concentrator and home oxygen concentrator, oxygen concentrator is also called medical molecular sieve oxygen concentrator, home molecular sieve oxygen concentrator, small medical oxygen concentrator, portable oxygen concentrator, medical oxygen concentrator.
Four kinds of hypoxia
1. Hypoxic hypoxia, usually caused by the decrease of PaO2 due to the insufficient amount of oxygen;
2. Blood hypoxia, usually caused by poor air circulation, being in a plateau area, carbon monoxide poisoning, hypoxemia, anemia, etc;
3. Circulatory hypoxia, which is caused by a decrease in tissue oxygen supply due to a decrease in tissue blood flow;
4. Tissue hypoxia, which is mainly reflected in the decrease of arterial and venous oxygen content difference, the partial pressure of oxygen and hemoglobin will be decreased, while the oxygen content of venous blood will be increased.
Hazards of Oxygen Deficiency
(1) Circulatory system: Lack of oxygen can cause palpitations and a fast or slow heartbeat. The peripheral burden on the heart increases and the heart contractility decreases, leading to arrhythmia and heart failure.
(2) Central nervous system: the nervous system and periphery, triggering cerebral infarction and peripheral thrombosis, manifested as dizziness, headache, slow reaction, fatigue and weakness, drowsiness and so on.
(3) Pulmonary organ effects: vasoconstriction (hypoxic pulmonary vasoconstriction), pulmonary hypertension (pulmonary hypertension); acute pulmonary edema.
Oxygen flow and oxygen concentration
Oxygen flow: refers to the oxygen concentrator's air output per minute, for example, 3L/min, means that the oxygen concentrator's air output per minute can be up to 3L (the oxygen concentrator's oxygen flow can be adjusted). The unit of oxygen flow is L/min.
Oxygen concentration: refers to the percentage of oxygen in the initial period of the oxygen concentrator. For example, 90% oxygen concentration means that the proportion of oxygen in the produced gas is 90%. The unit of oxygen concentration is percentage.
Portable Oxygen Concentrator Classification
1、Oxygen-enriched portable oxygen concentrator
Oxygen-enriched portable oxygen concentrator adopts “Oxygen-enriched membrane”, a kind of nano-scale polymer membrane with the function of enriching oxygen. Oxygen-enriched membrane is based on membrane separation technology, can be under a certain pressure, the use of air components through the membrane permeability of different, under the pressure difference in the air will be enriched in the oxygen, to reach the export of 30% of the concentration of oxygen, has the advantages of small size, small power consumption. And the first aid needed in the state of severe oxygen deficiency can only use medical high concentration of oxygen.
(1) Daily oxygen therapy: oxygen therapy is the most effective for hypotonic hypoxia, MTEHFYAY Oxygen Enrichment Instrument can effectively make up for the lack of ventilation and effectively replenish the body with the required oxygen to improve the physical dissolution of oxygen in the blood of patients with blood hypoxia and circulatory hypoxia. Give you clean and green oxygen-rich air from the source.
(2) Health care function: Improve the oxygen supply condition of the body by giving oxygen to achieve the purpose of oxygen supplementation and health care. Applicable to the middle-aged and elderly people, poor physical condition, pregnant women, college entrance examination students and other groups of people with different degrees of hypoxia, can also be used to eliminate fatigue and restore body functions after outdoor plateau way step, heavy physical or mental exertion. And for hypertension, coronary heart disease, diabetes, kidney function and other diseases can play a certain role in alleviating.
MTEHFYAF Oxygen Enriched Portable Oxygen Concentrator is divided into two models:
MT-EHFYAF-01: continuous oxygen supply;
MT-EHFYAF-03: two oxygen supply modes, continuous oxygen supply and pulse oxygen supply;
What is called continuous oxygen supply
It means that the oxygen supply equipment continuously provides oxygen regardless of whether the patient inhales or not. The oxygen utilization rate of this type of oxygen supply is low because oxygen can only enter the body when the patient inhales, while the oxygen during exhalation is directly wasted. Continuous oxygen supply is suitable for situations where a prolonged or continuous supply of oxygen is required.
MT-EHFYAF-03 Oxygen Enriched Portable Oxygen Concentrator with two modes of oxygen supply, continuous oxygen supply and pulse oxygen supply.
Both pulsed-flow and continuous-flow portable oxygen concentrators (POCs) provide supplemental oxygen to users who need it, but they deliver oxygen in different ways for different needs.
Pulse flow, also known as on-demand or intermittent flow (IF), delivers oxygen in short bursts or pulses during inspiration. It is designed to match your breathing pattern and conserve oxygen, making it more suitable for portable use and for people with lower oxygen needs or active lifestyles. On the other hand, Continuous Flow Oxygen (CF) delivers a constant and steady flow of oxygen regardless of breathing patterns.
2、Molecular sieve portable oxygen concentrator
(1) Molecular sieve portable oxygen generator (using pressure swing adsorption oxygen generator) is an advanced gas separation technology. It adopts physical method (PSA method) to extract oxygen directly from air, and it is fresh and natural, the maximum oxygen pressure is 0.2~0.3MPa (i.e. 2~3kg), and there is no danger of high pressure and easy to explode.
(2) Portable oxygen concentrator has the advantages of small size, portable, etc., the role is mainly to improve the oxygen content in the blood and oxygen reserves, so that the human body blood oxygen saturation is maintained in a healthy state, which in turn improves the body's metabolic ability and immunity, the high concentration of oxygen can effectively alleviate the symptoms of many diseases, such as COPD, pneumonia, respiratory failure, etc., and so on.
(3) It is especially suitable for short-time outing use of oxygen, such as the elderly going out for a walk, young people traveling to the plateau, and so on. Although it is suitable for short time use, it can save the emergency for patients who can't live without oxygen for 24 hours. It is able to supply oxygen according to the user's respiratory frequency, and adopts pulse-type oxygen delivery method, i.e., oxygen is delivered only when the user inhales, and stops delivering oxygen when exhaling, which ensures the effective utilization and comfort of oxygen.
Medical Oxygen Concentrator Indications
(1) Plateau reaction caused by hypoxia plateau environment characterized by low pressure, hypoxia, plains people into the plateau will generally occur in the respiratory system, circulatory system, digestive system, nervous system stress reaction.
(2) The so-called cardiovascular and cerebrovascular disease is a collective term for diseases of the blood vessels of the heart and the brain. Including hypertension, heart disease, coronary heart disease, myocardial infarction, cerebral thrombosis, cerebral ischemia, cerebral vertigo, atherosclerosis and so on.
(3) respiratory diseases, the main lesions in the trachea, bronchial tubes, lungs and chest cavity, lesions light more cough, chest pain, breathing affected, the heavy respiratory distress, hypoxia, and even respiratory failure and death. More attention should be paid to the incidence of chronic obstructive pulmonary disease (referred to as chronic obstructive pulmonary disease, including chronic bronchitis, emphysema, pulmonary heart disease), bronchial asthma, lung cancer, diffuse interstitial fibrosis of the lungs, as well as lung infections at home and abroad due to atmospheric pollution, smoking, population aging and other factors.
(4) Other symptoms that require oxygen therapy include weak and sickly people with poor immunity, heat stroke, gas poisoning, drug poisoning, etc.
Notes on the use of home oxygen concentrator
(1) Patients should read the instruction manual carefully before using the oxygen concentrator.
(2) Avoid open flame when using oxygen concentrator to avoid fire.
(3) The oxygen concentrator should be placed in a stable position, otherwise it will increase the noise of oxygen concentrator operation.
(4) The water level in the humidification bottle should not be too high (half of the water level in the bottle is appropriate), otherwise the water in the bottle is easy to escape or enter the oxygen absorbing tube.
(5) Wipe the surface of the oxygen concentrator clean, cover it with a plastic cover and store it in a dry place without sunlight.
(6) During transportation and storage, it is strictly prohibited to place it horizontally, upside down, wet or in direct sunlight.
How to choose the right oxygen concentrator?
(1) Understand the real needs, personal home or medical institution use.
(2) Requirements for flow rate and oxygen concentration: 3L is usually enough for direct oxygen intake, and 5L or more is necessary if paired with a ventilator.
(3) Oxygen concentrators used in medical institutions must be oxygen concentrators with registration certificates.
(4) Whether with atomization function, general model, there are W, said atomization.
