Missing is the pain that can breathe, yet still not being able to breathe hurts more. If you are afraid of pain, don’t be careless and prevent COPD as early as possible. What is chronic obstructive pulmonary disease (COPD)? A 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) is a silent killer. When chronic bronchitis and emphysema become irreversible airflow obstruction, COPD develops. Chronic obstructive pulmonary disease is characterized by long-term recurrent coughing, coughing and wheezing after activity, and over time it will evolve into pulmonary heart disease and involve other systems throughout the body. This time, chronic obstructive pulmonary disease not only involves the airways and lungs, but also is a systemic disease. However, it is a disease that can be prevented and treated. Who is prone to get “slow lung”? Long-term smokers, people over 40 years old, people with chronic respiratory diseases, people with long-term exposure to dust, and people with chronic cough symptoms are the five groups of people who are at high risk for slow lung and should have regular lung function tests. Risk factors of “slow obstructive pulmonary disease” 1, smoking is the main cause of slow obstructive pulmonary disease; 2, infection is one of the important factors that contribute to the development of slow obstructive pulmonary disease; 3, air pollution increases the conditions for bacterial infection; 4, occupational dust and chemical hazards; 5, genetic factors: lack of antitrypsin; 6, intrinsic factors of the body Weakening, autonomic dysfunction, nutrition, sudden changes in temperature, etc. ”For patients with chronic obstructive pulmonary disease, long-term home oxygen therapy can be used to improve the quality of life and prolong life expectancy. The correct method is to give low-flow oxygen (2~3L/min) for more than 15 hours a day. There are many patients who take oxygen at home intermittently for 2~3 hours per day, so that the effect of long-term oxygen therapy cannot be achieved. Some patients even wrongly believe that “oxygen inhalation will become addictive”. 2.For patients with chronic obstructive pulmonary disease in the stable stage, correct and effective pulmonary function exercises can improve the respiratory function of patients, delay the deterioration of pulmonary function, and improve the quality of life of patients. For example, lip retraction breathing (similar to whistling to increase breathing resistance and thus exercise respiratory muscles). 3, abdominal breathing exercises: through the active diastolic 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 improving the exercise endurance of patients. 4, whole body muscle training: such as fast walking, biking in place, stair climbing, etc., as well as muscle training of the upper limbs, which can also improve the quality of life of patients. Diet For patients with chronic obstructive pulmonary disease, a diet low in carbohydrates (low sugar) and high in protein and fiber is recommended, while avoiding foods that produce gas. Excessive carbohydrate intake will produce too much carbon dioxide during digestion, which will inevitably increase the ventilatory load for patients with chronic obstructive pulmonary disease. A low-sugar diet is also a way to avoid excessive carbon dioxide in the blood and reduce the respiratory burden. High fiber foods can prevent constipation. By avoiding gas-producing foods, bloating can be prevented. Consuming high protein foods whenever possible will increase energy levels and contribute to strong muscles and bones.
