Once a person is diagnosed with chronic obstructive pulmonary disease, it is necessary to provide early and consistent treatment. Patients with chronic obstructive pulmonary disease should take medication strictly as prescribed by the doctor and should not stop it on their own, and should be reviewed regularly at the hospital. When chest tightness, shortness of breath and hypoxia occur, patients should also use continuous low-flow oxygenation. Reasonable home oxygen therapy can relieve the patient’s hypoxic symptoms, prevent the aggravation of the disease and improve the patient’s survival quality. Medication is necessary for patients with chronic obstructive pulmonary disease. Some patients are more likely to accept oral or intravenous medication when receiving treatment and are not accustomed to inhaled medication therapy, but in fact, inhaled medication can be better for patients with respiratory disease. Inhaled drugs are made according to the characteristics of the lungs, and the alveoli are 90 square meters in area after being unfolded, which is as big as 1/4 basketball court. There is not only a rich blood circulation system on the alveoli, but also drug receptors exist, and a spray of inhaled drugs to the patient can make the drugs act directly on the airway, with rapid onset of action, and reduce the absorption of drugs throughout the body, and with little side effects. Therefore, it has outstanding advantages in the treatment of chronic obstructive pulmonary disease.
