What is pneumonia? Influenza is a disease of the respiratory system which have caused serious epidemics in the past. Pneumonia represent any inflammation of the lungs caused by several different microorganisms(微生物),it also named pneumonitis. Lobar pneumonia(大叶性肺 炎):streptococcal pneumonia usually involves one or more lobes of the lung Bronchopneumonia: A kind of pneumonia in the bronchial tubes Definition: Pleurisy (胸膜炎)is an inflammation of the pleura, which is the moist, doublelayered membrane that surrounds the lungs and lines the chest cavity. The Cause : It can attend condition can make pneumonia or result breathing extremely from direct infection painful. of the pleura. Tuberculosis(结核病) Resulting form the rise of AIDS and the appearance of resistance to antibiotics(抗生素) The most common symptoms and signs of TB are fatigue(疲劳), fever, weight loss, coughing, hemoptysis(咯 血) and night sweats(盗汗). The tuberculosis skin test is a test used to determine if someone has developed an immune response to the bacterium that causes tuberculosis (TB). This response can occur if someone currently has TB, if they were exposed to it in the past, or if they received the BCG vaccine against TB . The tuberculosis skin test is also known as the tuberculin test or PPD test The WHO estimates that 2 billion people worldwide have latent TB, while around 3 million people worldwide die of TB each year. What Is Asthma? Asthma is a chronic (long-term) lung disease that inflames and narrows the airways. Leading to wheezing, shortness of breath, chest tightness, and coughing. The coughing often occurs at night or early in the morning Asthma 哮喘 Figure A shows the location of the lungs and airways in the body. Figure B shows a crosssection of a normal airway. Figure C shows a cross-section of an airway during asthma symptoms. Common asthma causes include: Animals (pet hair or dander) Dust Changes in weather (most often cold weather) Chemicals in the air or in food Exercise Mold Pollen Respiratory infections, such as the common cold Strong emotions (stress) Tobacco smoke Treatment The goal of treatment is to avoid the substances that trigger your symptoms ,control airway inflammation , administration of bronchodilators to widen the airway and administration of steroids. Respiratory distress syndrome Respiratory distress syndrome is a breathing disorder of premature newborns in which the air alveoli in a newborn's lungs do not remain open because the production of a substance that coats the alveoli is absent or insufficient. Respiratory distress syndrome is a potentially life-threatening medical condition where the lungs cannot provide enough oxygen for the rest of the body. Symptoms of respiratory distress include: blue-coloured lips, fingers and toes rapid, shallow breathing rapid heartbeat Treatment may involve cutting a hole through the windpipe and passing a tube attached to a mechanical respirator through the hole. The patient may be placed on a heat and lung machine that maintains respiration and heartbeat Baby special care Find out about special care given to babies born early, or those who are sick, jaundiced or born with a disability. Acute Pulmonary Oedema 急性肺水肿 It occurs when fluid quickly accumulates in the lungs and fills the alveoli(肺泡) This can cause problems with the exchange of gas (oxygen and carbon dioxide), resulting in breathing difficulty and poor oxygenation of blood. Treatment:oxygen, digitalis(洋地黄),diuretics (利尿剂) What is a pneumothorax? A pneumothorax is a collection of free air in the chest outside the lung that causes the lung to collapse. What causes a pneumothorax? Pneumothorax is caused by a wound in the chest ,such as a knife wound,or after a sudden tear in the lung. Infection of the pleural space by gas -producing microbes can also cause pneumothorax. Pneumothorax can also develop as a result of underlying lung diseases, including cystic fibrosis, chronic obstructive pulmonary disease (COPD), lung cancer, asthma, and infections of the lungs. Treatment: 1 Removing the gas by suction(抽吸) 2 Surgically repairing the chest and lung 3 Antibiotics (抗菌药) Pneumoconiosis 尘肺病 also known as "black lung" Pneumoconiosis: The deposition of particulate matter such as asbestos and silicon in the lungs Emphysema 肺气肿 Emphysema is included in a group of diseases called chronic obstructive pulmonary disease or COPD. Cigarette smoking is by far the most dangerous behavior that causes people to develop emphysema, and it is also the most preventable cause. Other risk factors include a deficiency of an enzyme called alpha-1-antitrypsin, air pollution, airway reactivity, heredity, male sex, and age. Chronic obstructive pulmonary disease 慢性阻塞性肺疾病 Learn about COPD Including: chronic bronchitis chronic obstructive bronchitis asthmatic bronchitis emphysema Simple chronic bronchitis 单纯慢性支气管炎 A syndrome characterized primarily by a chronic productive cough,is the low-grade exposure to bronchial irritants in a individual without hyperreactive airways. Clinical terms 1 Excessive production of mucus 2 Presence of symptoms,large cough,on most days for at least three months annually during two or more successive years 3 Exclusion of bronchiectasis ,tuberculosis,or other causes of these symptoms Chronic obstructive bronchitis 慢性阻塞性支气管炎 Chronic obstructive pulmonary disease (COPD) is a progressive and debilitating lung disease. The disease is characterized by irreversible airflow limitation in the lungs. Brochospasm Espiodic airways obstruction is common in individuals with chronic bronchitis. this combination ,called asthmatic bronchitis, may closely resemble classic asthma. the term chronic asthmatic bronchitis is applied in patients with persistent airways obstruction, a chronic productive cough, and a major problem of opisodic bronchspasm. Emphysema Emphysema is a long-term, progressive disease of the lungs that primarily causes shortness of breath due to over-inflation of the alveoli (air sacs in the lung). In people with emphysema, the lung tissue involved in exchange of gases (oxygen and carbon dioxide) is impaired or destroyed. Type A 、B Breathing With Emphysema To my classmates
