Hypoxia Response Programs for Different Populations

1. Patients with cardiovascular and cerebrovascular diseases
Patients with cardiovascular and cerebrovascular diseases often face the risk of dizziness, headache, chest tightness, palpitations and even sudden emergencies due to poor blood circulation and insufficient blood oxygen supply! Long-term chronic hypoxia will increase the burden on blood vessels and induce serious consequences such as cerebral infarction and myocardial infarction. Our oxygen concentrator protects life and health with professional oxygen therapy! 2-9L/min wide range flow adjustment, which can be flexibly adjusted according to the condition: daily health care with low flow gentle oxygen supplement to improve blood circulation; in case of sudden discomfort, 9L large flow rapid oxygen supply, relieve myocardial ischemia, cerebral insufficiency caused by hypoxia symptoms, and buy precious time for rescue. ≥93% stable oxygen concentration, continuously inject vitality into the heart and brain organs, reduce vascular pressure, and reduce the risk of disease.

2. Mild hypoxia (hypoxia) state or discontinuity
Some patients are in a mild hypoxia (hypoxia) state or discontinuity. Increased activity, excessive mental tension, overeating, and supine sleep at night often induce or aggravate hypoxia. Our products are suitable for people who have mild hypoxia symptoms, such as occasional dizziness, shortness of breath, lack of concentration, etc., and the hypoxia state is not continuous. Whether it is a short-term discomfort caused by environmental changes or mild hypoxia caused by daily fatigue, this oxygen concentrator can replenish oxygen in time and quickly restore vitality.

3. Some patients in the recovery period of acute diseases
For example, acute myocardial infarction, acute cerebral infarction, severe myocarditis, severe pneumonia, or after cardiothoracic surgery, the body is in a fragile recovery period, and it is easy to slow down the pace of recovery due to mild hypoxia and hypoxemia. Our products have an adjustable flow of 2-9 liters, which fits different scenarios: daily lying and recuperating, low-flow continuous oxygen supply, slowly improving the body’s hypoxic microenvironment; when doing a little activity, increase the flow as needed to meet the additional oxygen demand in the state of exercise. 93% high-concentration oxygen quickly increases blood oxygen saturation, “delivers energy” to damaged myocardium and brain tissue, promotes cardiopulmonary function repair, helps brain function recovery, and accelerates the body’s recovery process. Flexible flow adjustment, which can be adjusted dynamically according to the condition: when the hypoxia is mild during the recovery period, use low flow to maintain basic oxygen supply; if there is a short-term hypoxia fluctuation, increase the flow to quickly relieve it.

4. Anemia people
Due to the weak oxygen carrying capacity of the blood, anemia people are prone to hypoxia symptoms such as dizziness, fatigue, and shortness of breath. Long-term hypoxia can damage cardiopulmonary function and affect life. The capacity of this product can be adjusted between 1 liter and 9 liters. It can directly supplement high-concentration oxygen according to your symptoms, bypass the oxygen-carrying barrier caused by anemia, allow oxygen to reach cells directly, quickly relieve hypoxia discomfort, and replenish energy for the body.

5. Acute heart failure patients
When acute heart failure occurs, every breath is a race against time! Rapid panting, chest tightness and suffocation, and a sudden drop in blood oxygen, every second of hypoxia may increase the burden on the heart and endanger life! This product is designed for emergency and long-term oxygen therapy needs! The 2-9L ultra-large flow rate is precisely adjustable, and can quickly output high-flow oxygen (up to 9L/min) during acute attacks, quickly increase blood oxygen concentration, and relieve dyspnea; stable oxygen concentration reduces the pressure on the fragile cardiopulmonary system, and buys golden time for rescue and rehabilitation. Supports continuous and uninterrupted oxygen supply throughout the day to meet the all-weather oxygen therapy needs of patients with acute heart failure.

6. Acute attacks of bronchial asthma or epilepsy
When bronchial asthma attacks suddenly, accompanied by severe wheezing and dyspnea, or acute attacks of epilepsy are accompanied by respiratory depression, oxygen therapy support against time is the key to protecting life. This product can quickly increase the flow rate during an asthma attack, quickly relieve the symptoms of hypoxia caused by airway spasm; when acute attacks of epilepsy cause abnormal breathing, it can also provide sufficient oxygen in time to stabilize blood oxygen levels. Stable oxygen concentration protects the fragile respiratory system and reduces the risk of complications caused by hypoxia.

Application Scenario

Packing Accessories

Working Principle

Air enters the compressor after filtered by the air inlet filter and is compressed into molecular sieve tower for separation of oxygen gas and nitrogen gas. Then, oxygen gas passes through the molecular sieve tower and enters the fine sieve tower smoothly, while nitrogen gas is discharged into the atmosphere through the separating valve after adsorbed by the molecular sieve. After the concentration of oxygen gas is further increased in the fine sieve tower, the flow rate is controlled by the flow control valve, and then oxygen gas is wet through the humidification water tank and finally flows through the oxygen delivery pipe for supplementary oxygen inhalation by users.
