What is Chronic Obstructive Pulmonary Disease (COPD) The disease that causes 2.5 deaths per minute by holding your breath and making it difficult to breathe is known as the “silent killer”, or “COPD” for short. Chronic obstructive pulmonary disease (COPD) develops when what is often referred to as chronic bronchitis and emphysema become irreversible airflow obstruction. Chronic obstructive pulmonary disease (COPD) is characterized by chronic recurrent coughing, sputum coughing and wheezing after activities, which will evolve into pulmonary heart disease over time, and will also involve other systems of the body. It is a systemic disease that affects not only the airways and lungs. However, COPD is a preventable and treatable disease. Long-term smokers, people over 40 years of age, patients with chronic respiratory diseases, long-term exposure to dust, chronic cough symptoms, these five groups of people are at high risk of chronic obstructive pulmonary disease, should be regularly conducted lung function tests. “Risk factors of chronic obstructive pulmonary disease (COPD): 1) Smoking is the main cause of COPD; 2) Infection is one of the most important factors contributing to the development of COPD; 3) Air pollution increases conditions for bacterial infections; 4) Occupational dust and chemical hazards; 5) Genetic factors: lack of trypsin; 6) Intrinsic factors; 7) Weakened autonomic dysfunction; 8) Lung dysfunction; 9) Lung function tests; 10) Lung function tests; 11) Lung function tests; 12) Lung function tests; 13) Lung function tests. Weakening of intrinsic factors, autonomic dysfunction, nutrition, sudden changes in temperature and so on. “Home protective measures for patients with chronic obstructive pulmonary disease (COPD) 1. Long-term home oxygen therapy can be used for patients with chronic respiratory failure in the stabilized stage of COPD, which can achieve the therapeutic effect of improving the quality of life and prolonging the life span. The correct method is to give low-flow oxygen (2~3L/min) for more than 15 hours a day. Many patients have intermittent oxygen intake at home for 2~3 hours per day, which cannot realize the effect of long-term oxygen therapy. Some patients even wrongly believe that “oxygen inhalation is addictive”. 2, stable chronic obstructive pulmonary patients, daily use of correct and effective pulmonary function exercise can improve the patient’s respiratory function, delay the deterioration of lung function, improve the quality of life of patients. For example, lip-contraction breathing (similar to whistling to increase the resistance to breathing and thus exercise the respiratory muscles). 3, abdominal breathing exercise: through the active diastole and contraction of the abdominal muscles to strengthen the abdominal muscle movement, thereby improving lung ventilation, reducing oxygen consumption, reducing the symptoms of dyspnea, and improve the patient’s exercise endurance. 4, whole-body muscle training: such as fast walking, in situ cycling, stair climbing, etc., as well as muscle training of the upper limbs, can also improve the quality of life of patients. Diet Patients with chronic obstructive pulmonary disease are advised to adopt low-carbohydrate (low-sugar), high-protein, high-fiber foods in their diet, while avoiding gas-producing foods. Excessive intake of carbohydrates will produce too much carbon dioxide during digestion, which will inevitably increase the ventilatory load for patients with chronic obstructive pulmonary disease (COPD). A low-sugar diet is also a good way to avoid too much carbon dioxide in the blood and to reduce the respiratory burden. High-fiber foods prevent constipation. Bloating can be prevented by avoiding gas-producing foods. Consume high protein foods whenever possible, which will increase energy levels and contribute to strong muscles and bones.
