Ventilator: It is mainly to improve the symptoms of cough, phlegm, and asthma. The ventilator is mainly to help patients improve the symptoms of cough, phlegm, and asthma, as well as the problem of carbon dioxide retention. When COPD develops to type II respiratory failure, the patient can no longer breathe smoothly. With the decline of his expiratory function, the patient cannot normally excrete carbon dioxide from the body, which will lead to the retention of carbon dioxide for a long time. , causing hypercapnia, which can lead to coma or even death in severe cases.
Oxygen generator: mainly to improve the symptoms of hypoxia, the oxygen generator can produce high concentration of oxygen, so that the oxygen is mixed with the normal inhaled air, so as to improve the oxygen content of the patient's inhaled air. To put it simply, the oxygen generator mainly deals with the lack of oxygen in the body. When the COPD patient's blood oxygen saturation drops below 90%, it indicates that the body is in hypoxia, and it is necessary to use an oxygen concentrator for home oxygen therapy. Note: Oxygen therapy is only an auxiliary means to correct pathological hypoxia, it cannot deal with the cause of hypoxia from the root.
The ventilator and the oxygen concentrator perform their own duties, and each plays a great role
The ventilator blows air into the body. Its function is to help and replace the patient's breathing work, relieve respiratory muscle fatigue, and assist breathing well, but it cannot increase the oxygen content and oxygen reserve in the blood in time.
The oxygen generator is like a precise sieve, sieving out the oxygen in the air, purifying it and supplying it to the patient, which can improve the hypoxia, keep the blood oxygen saturation of the human body in a healthy state, and then improve the metabolism of the human body. and immunity. Therefore, the two are completely irreplaceable. Ventilators and oxygen concentrators can be used in combination. Given the development of COPD, patients often require long-term home treatment. The most common treatment method at this time is non-invasive ventilator combined with oxygen concentrator, and home use with ST mode. Bi-level non-invasive ventilator, and oxygen concentrator above 5L (five liters).
The ventilator has five modes: "S", "T", "S/T", "CPAP", and "VAT", which can provide COPD patients with a higher inspiratory pressure and a lower expiratory pressure, which is a good way to deal with slow breathing. The most effective model for patients with obstructive pulmonary disease. When inhaling, the ventilator can provide a higher inspiratory pressure for the patient, which helps the gas to be inhaled smoothly and enter the patient's lungs. When the patient exhales, the ventilator can actively reduce the pressure, creating a pressure difference. Under the action, it helps the patient to expel the excess gas in the alveoli, so as to carry out effective gas exchange, relieve the symptoms of dyspnea, and relieve the pressure of the diaphragm.
