Chronic obstructive pulmonary disease (COPD), as a common respiratory disease, has become one of the third largest health killers in China. Many patients have significantly decreased their quality of life and even lost their lives due to COPD. In recent years, the incidence of chronic obstructive pulmonary disease (COPD) has been increasing year by year due to factors such as living environment and behavior. For most people, chronic obstructive pulmonary disease is still one of the relatively unfamiliar diseases. What are its symptoms? How should we take care of it? 1、 What are the symptoms of chronic obstructive pulmonary disease? 1. Cough: Cough in COPD patients has the characteristics of long-term, gradual worsening, and recurrence. At the beginning, the cough symptoms appeared intermittent, with more severe symptoms in the morning. As the condition worsened, the patient experienced cough symptoms both in the morning and at night, especially during the winter and spring seasons, when the disease became apparent. 2. Sputum coughing: The color of the sputum is gray white, and the shape is mucous. The amount of sputum in the morning is relatively large; When combined with infection, the amount of sputum will significantly increase. 3. Difficulty in breathing and shortness of breath: This symptom only appears in the early stage after heavy physical labor, and gradually worsens as the condition worsens. Shortness of breath can also be felt during daily rest and activities. 4. wheezing and chest tightness: This symptom is not a specific symptom for patients with chronic obstructive pulmonary disease. For patients with severe chronic obstructive pulmonary disease, there will be a feeling of wheezing. Generally, after exertion, there will be a significant tightness in the chest, which is related to intercostal muscle contraction and difficulty breathing. 5. Other symptoms: loss of appetite, weight loss, anxiety, depression, etc; If the patient is co infected, it is easy to cause hemoptysis or hemoptysis. 2、 What are the nursing methods for patients with chronic obstructive pulmonary disease? 1. Dietary and nutritional supplements are very important for patients with chronic obstructive pulmonary disease. Firstly, in terms of dietary matching, eat more protein rich foods, such as beans and dairy products; In addition, eating more foods rich in vitamins and calcium, such as vitamin A foods such as carrots, fish oil, beef liver, and egg yolk, is beneficial for maintaining the trachea, moistening the lungs, and relieving cough; Vitamin C foods include tomatoes, red dates, grapefruit, etc., which are beneficial for preventing infections, colds, and cancer; Foods rich in calcium include vegetables, water tofu, peanut butter, etc. Their function is to enhance the sensitivity of the trachea. Secondly, try not to eat spicy and highly stimulating foods, otherwise these foods will further aggravate the irritation to the tracheal mucosa, leading to discomfort such as palpitations, shortness of breath, and dry cough in patients. 2. Actively quitting smoking is a very important step for the general population with chronic obstructive pulmonary disease, and the harmful substances in tobacco are important factors that exacerbate disease symptoms. If patients persist in quitting smoking, the rate of decline in lung function will be significantly slowed down; The progression of the disease will also slow down, reducing the risk of worsening symptoms and making the body's breathing more relaxed, thereby helping patients recover normal lung function. 3. It is crucial for patients with chronic obstructive pulmonary disease to receive long-term medication according to medical advice. It is not correct that patients often stop taking medication on their own in daily life, leading to a gradual worsening of the condition. The improvement of symptoms only indicates that the disease has been controlled, and cannot indicate that the disease has been cured or lung function has returned to health. Changing medication, reducing medication dosage, or stopping medication can easily lead to disease recurrence, and even symptoms gradually worsen. The most correct treatment method is root
