Chronic Obstructive Pulmonary Disease (COPD), or slow-onset lung for short. It is a devastating lung disease that mainly manifests as coughing, coughing, wheezing and shortness of breath, which will gradually weaken the patient’s respiratory function. It includes chronic bronchitis, bronchial asthma, chronic obstructive pulmonary emphysema, and chronic pulmonary heart disease. This disease can develop without obvious discomfort, especially in the early stage, many organs have a strong physiological compensatory capacity, some organs may not have much effect if their function decreases by about 30%, but once it reaches 40%, the loss of function will increase exponentially, and many problems will be exposed, when patients feel “tightness in the chest, can’t get air, there is When the patient feels “chest tightness, can’t get up to the air, there is something pressing on the chest”, it is already in the middle and late stage, and the mortality rate can be as high as 20-30% within 5 years. The risk factors for the development of chronic obstructive pulmonary disease include individual susceptibility factors and environmental factors, among which smoking can lead to a 10-43% increase in the risk of adult morbidity, which is one of the most important risk factors, while passive smoking is also a serious risk factor. If chronic obstructive pulmonary disease can be diagnosed and treated at an early stage, it can greatly reduce the mortality rate and improve the quality of life of patients. Chronic obstructive pulmonary disease can be diagnosed by early pulmonary function tests, which require only a few puffs of air and are as simple as taking blood pressure. Since the onset of the disease is mostly after the age of 40, smokers over the age of 40 should have their lung function checked once a year. In addition, the following quiz will help you to have a general idea of lung function: 1. How many times a day do you often cough? 2.Do you often have phlegm? 3.Do you feel short of breath more often than people your age? 4.Are you older than 40 years old? 5. Do you currently smoke or have you ever smoked? If you answered “yes” to three or more questions, ask your doctor if you want to have a simple pulmonary function test to get an early diagnosis. Once you have COPD, you should go to a regular hospital for regular treatment and rehabilitation under the guidance of your doctor. Although there is no complete cure and no specific medication, there are many effective medications to control the development and recurrence of the disease and improve the quality of life of patients. If you pay attention to the following aspects of your health is also very beneficial: 1, to ensure that the indoor air is fresh, to avoid respiratory irritation. 2. Patients who smoke should quit smoking and avoid passive smoking. 3.Patients who have the conditions can be oxygen therapy at home. 4.Adhere to breathing exercises training, improve respiratory function. 5.Strengthen personal protection, in the cold season or climate change, pay attention to the cold to keep warm, to prevent respiratory tract infection, once the infection should be timely and thorough treatment, this is essential. 6, reasonable diet to enhance resistance and reduce the chance of infection.
