For an extended time, people believe that oxygen therapy is an efficient method for severe patients, especially for patients with the chronic obstructive pulmonary disease with severe symptoms of hypoxia, which may play an efficient role in relieving the patients' life-threatening lethargy. Once things recover, people take it without any consideration that they do not go to inhale oxygen anymore, and it's worry whether Long-term oxygen inhalation will make people become addicted and be harmful.

In fact, these opinions are caused by the shortage of sufficient understanding of oxygen therapy. the necessity for long-term oxygen inhalation isn't thanks to dependence and addiction to oxygen, but precisely due to chronic hypoxia within the body. Patients with chronic obstructive pulmonary disease suffer from severe hypoxia for an extended time, and are susceptible to symptoms like shortness of breath, fatigue, amnesia, and even cyanosis of the lips, fingers, and toenails, and even cause dysfunction and damage to the brain, heart, liver, and kidneys. The more severe the hypoxia, the sooner the occurrence of cor pulmonary. additionally, long-term hypoxia also can affect the body's immune defense function, so it's susceptible to repeated respiratory infections.

The doctor recommends that some patients with chronic obstructive pulmonary disease got to continue long-term home oxygen therapy after their acute illness is controlled. the right oxygen therapy can delay the progression of the disease, reduce respiratory infections, and improve the patient's quality of life.

The goal of long-term home oxygen therapy is to stop severe hypoxia during rest, sleep and activities in patients with COPD through oxygen therapy, and eliminate the adverse effects of chronic hypoxia on health, like correcting hypoxaemia and reducing pulmonary arteries. Compression and delay the progression of pulmonary heart condition, etc., can ultimately prolong the survival time of patients and improve the standard of life.

Of course, not all patients with chronic obstructive pulmonary obstruction should be treated with long-term oxygen therapy. The clinical practice is especially for patients with chronic obstructive pulmonary disease who have the subsequent indications: after smoking cessation, medication and other treatments are stable, the patient still has arterial hypoxaemia at rest that’s, when breathing indoor air, its blood oxygen partial pressure is a smaller amount than or adequate to 55mmHg. If the partial pressure of blood oxygen is 55-59mmHg, the subsequent conditions should even be inhaled, like secondary hypoglycemia; pulmonary hypertension; right coronary failure.

Patients with COPD should strengthen their own functional exercises. Although these patients often have a particular degree of breathing difficulties, they can't stop exercising. Appropriate rehabilitation training is extremely helpful to the steadiness of the disease. This emphasizes the necessity to breathe Find a balance between difficulty and exercise intensity. Of course, there also are some more scientific evaluation methods, like exercise cardiopulmonary function to guage the patient's exercise ability, and formulate corresponding exercise prescriptions accordingly. For patients taking oxygen, rehabilitation exercises should be performed under oxygen inhalation.

Chronic obstructive pulmonary disease may be a common and frequently-occurring disease within the systema respiratorium of the elderly, especially in winter when the climate changes drastically and therefore the temperature drops sharply. Therefore, once diagnosed with chronic obstructive pulmonary disease, you want to seek medical treatment in time and adopt professional and standardized treatment methods. COPD patients enforce daily home oxygen therapy for a minimum of 7-8 hours each day, with a 5-liter oxygen concentrator because the mainstay, and must be equipped with oxygen concentration detection and temperature detection.

Home oxygen therapy:

How many liters of oxygen concentrators do patients with COPD need?

Family oxygen therapy requires a 3--10 liter oxygen concentrator (depending on the condition). consistent with the connection between the inhaled oxygen concentration and therefore the flow, only 41% of the oxygen within the patient's body are often inhaled by the 5-liter oxygen concentrator. this is often the worth under ideal conditions. In fact, the oxygen inhaled by the 5-liter machine in patients with COPD is quite 30%. That is, the doctor said that oxygen with a coffee oxygen concentration of about 30 should be used for discharge. This refers to a 5-liter oxygen generator. Whether the patient uses 3 liters, 5 liters or 10 liters, it depends on the patient’s blood oxygen saturation above 90% (Generally 94% is sufficient) because the target. for instance, for patients with chronic obstructive pulmonary disease who use a 5-liter machine but the blood oxygen saturation is below 90%, a large-flow oxygen concentrator above 5 liters should be used. Oxygen therapy time: starting from 7-8 hours each day to quite ten hours, very serious quite 20 hours.
