What is oxygen inhalation?
Oxygen is very important to the human body. Under normal conditions, healthy people breathe air naturally and use the oxygen in it to maintain their metabolic needs. In case of illness or some abnormal state, it is necessary to inhale oxygen through a certain device at home or in a clinic or hospital.
Oxygen inhalation therapy refers to a method of supplying oxygen to patients, increasing arterial partial pressure of oxygen (PaO2) and oxygen saturation (SaO2), improving the state of hypoxia, promoting metabolism, and maintaining life activities.
What are the benefits of oxygen inhalation?
1.Oxygen inhalation can alleviate angina pectoris and prevent myocardial infarction: Angina pectoris is caused by acute myocardial hypoxia. Myocardial insufficiency for more than 30 minutes can caus5e myocardial infarction and is a major risk factor for sudden death of patients. Regular health care oxygen inhalation or onset of illness can prevent or alleviate the occurrence of angina pectoris and myocardial infarction, and gain time for treatment.
2.Oxygen inhalation can prevent sudden death of coronary heart disease: Sudden death of coronary heart disease is unpredictable due to sudden onset. It often has mild mild chest tightness, shortness of breath, emotional abnormality, or heart rhythm confusion before its onset. If it can be supplemented with oxygen at this time Treatment can do more with less.
3.Oxygen inhalation has obvious treatment for asthma: Asthma is caused by the weakening of the ventilation function of the alveoli and the outside world due to bronchospasm and other conditions. Oxygen absorption can increase the oxygen concentration in the alveoli and help to alleviate asthma symptoms.
4.Oxygen inhalation can effectively treat emphysema, pulmonary heart disease, and chronic bronchitis: The diseases listed above are caused by severe hypoxia.Oxygen inhalation can reduce the symptoms of hypoxia and significantly increase blood oxygen saturation. It’s better than medication alone.
5.Oxygen inhalation has an adjuvant treatment effect on diabetes: Studies have shown that diabetes is related to the body's hypoxia. Capillary blood pressure is significantly lower in diabetic patients, and tissue cells cannot obtain sufficient oxygen, which leads to impaired cell function and glucose metabolism. Therefore, the implementation of oxygen therapy for diabetic patients has attracted great attention from the medical community.
6.Oxygen inhalation can play a health care role for healthy people: Due to the increasingly serious air pollution and the widespread use of air conditioners, regular oxygen inhalation can clean your respiratory system, improve visceral function, and improve the overall immunity of the human body to prevent various diseases.
What are the commonly used oxygen therapy?
First, nasal oxygen inhalation method
The oxygen absorption method is simple and convenient to use.Nasal oxygen inhalation is an open-style oxygen inhalation, that is, when a person takes a breath, some air (20% (V / V) oxygen purity) next to the patient is inhaled, so that the patient is more comfortable.But the nasal oxygen inhalation under 3L, oxygen has no therapeutic value. In the process of oxygen treatment, the oxygen purity and oxygen flow should be paid great attention. At the same time, the nasal oxygen tube needs to add water to the humidifier bottle to humidify the oxygen and prevent the airway mucosa from drying out.
Second, mask oxygen inhalation
Mask oxygen inhalation can be divided into open and closed mask method. The open type is to put the mask at place of 1-3 cm away from the patient's mouth and nose, which is suitable for children without any discomfort. The closed mask method is to tightly cover the mask on the mouth and nose and fix it with elastic bands, it is suitable for people with severe hypoxia. The concentration of oxygen inhaled can reach 40% to 50%, patients feel more comfortable, without mucous membrane irritation and dry blowing. However, the oxygen consumption and the pressure in the mask is large. When the flow rate is less than 5L / min, oxygen cannot enter the mask well, so it cannot enter the respiratory track and lungs. At the same time, the exhaled carbon dioxide cannot be flushed out of the mask, thus which affects the treatment effect.
Third, electronic pulse oxygen therapy
It is a new method developed in recent years. It can automatically supply oxygen when inhalation and automatically stop supplying oxygen during the exhalation through an electronic pulse device. This is more consistent with the physiological state of breathing and greatly saves oxygen.
Four, mechanical aerated oxygen method
When using various artificial respirator for mechanical ventilation, the oxygen supply device on the ventilator is used for oxygen therapy. The supplied oxygen purity can be adjusted according to the disease condition (21% ~ 100%). The oxygen source by mechanical aerated oxygen method is generally used home oxygen concentrator,which are currently used the home oxygen concentrator with a flow rate of 5L or more. Long-term home oxygen therapy is using ventilator machine with oxygen concentrator to cure.
