Bronchial dilation diagnostic methods
Bronchiectasis refers to the inflammation of the bronchi and surrounding lung tissue caused by various diseases and etiologies. This inflammation leads to the destruction of the muscles and some elastic tissues of the bronchial walls, resulting in the deformation and persistent dilation of the bronchi, which cannot recover, collectively known as bronchiectasis. The definitive diagnosis of bronchiectasis is most commonly based on clear clinical symptoms such as significant coughing, phlegm production, and hemoptysis; secondly, cystic and cylindrical dilations in the patient’s bronchi can be clearly seen through chest CT and high-resolution CT, allowing for a direct diagnosis of bronchiectasis.
Mycoplasma pneumoniae can cause
Mycoplasma pneumoniae can cause mycoplasma pneumonia, which refers to the acute inflammatory changes in the respiratory tract and lungs caused by Mycoplasma pneumoniae. At the same time, there can be pharyngitis, bronchitis, and pneumonia. Mycoplasma pneumonia accounts for more than one-third of non-bacterial pneumonia, or 10% of pneumonia caused by various reasons. Mycoplasma pneumoniae pneumonia is more prevalent in the autumn and winter seasons, but the seasonal differences are not significant. After being infected with mycoplasma pneumonia, the first symptom may be fatigue, sore throat, and headache, followed by paroxysmal coughing, fever, loss of appetite, and some people may experience diarrhea, muscle pain, ear pain, etc. Most cases of Mycoplasma pneumoniae pneumonia can be cured, but a small number of people may worsen, requiring medical treatment.
How is bronchiectasis treated?
Bronchiectasis refers to the deformation and dilation of the bronchi due to chronic inflammation and fibrosis of the bronchi and surrounding lung tissue, which damages the muscles and elasticity of the bronchial walls. Clinically, this condition is known as bronchiectasis. The most typical symptoms include long-term coughing, coughing up large amounts of purulent sputum, and repeated instances of coughing up blood among others. Once bronchiectasis is diagnosed, it needs to be treated: First, we can clear the secretions from the bronchi, usually through nebulization to thin the mucus, and bronchoscopy or other local irrigation methods to clear the secretions inside. Second, after bronchiectasis occurs, we need to perform anti-inflammatory treatment for the bacteria infesting the bronchi, usually using sensitive antibiotics for treatment. Third, it is necessary to enhance the patient’s own immunity to prevent frequent recurrent infections. Fourth, if conservative treatment is not effective, surgical methods can be used to remove parts of the dilated bronchi, thereby achieving the treatment purpose.
Is pulmonary heart disease serious?
Cor pulmonale refers to the disease characterized by changes in the structure and function of the right ventricle due to increased pressure resistance in the pulmonary vessels, caused by abnormalities in the bronchopulmonary tissue, thoracic cage, pulmonary vessels, etc., ultimately leading to pulmonary arterial hypertension. Common symptoms of cor pulmonale observed clinically include coughing, production of phlegm, shortness of breath, chest tightness after activity, and difficulty breathing. Some individuals may experience respiratory failure and symptoms of heart failure. The severity of cor pulmonale depends firstly on the underlying causes of the disease. For instance, conditions like pulmonary embolism and pulmonary hypertension generally have a poorer and more serious prognosis. Secondly, extensive lung infections leading to a loss of cardiopulmonary compensation, resulting in respiratory failure and heart failure, typically indicate a more severe condition.
Symptoms of cor pulmonale
Cor pulmonale refers to a disease characterized by increased pulmonary vascular resistance due to pathologies of the bronchi, lung tissue, chest wall, and blood vessels of the lungs, leading to pulmonary arterial hypertension and structural and functional changes in the right ventricle. The common clinical symptoms of cor pulmonale include coughing, expectoration, shortness of breath, significant palpitations, and breathing difficulties after physical activity, reduced work capacity, and exacerbation of the above symptoms during acute infection phases. Some patients may experience chest pain and hemoptysis. The second set of symptoms relates to heart and lung function, manifesting during the decompensation phase. For instance, some patients may develop respiratory failure, and experience headaches, decreased appetite, drowsiness, significant edema in the lower extremities, and further symptoms such as arrhythmias, anorexia, abdominal distension, and nausea.
Manifestations of Cor Pulmonale
Cor pulmonale refers to a disease characterized by changes in heart structure and function due to increased pulmonary vascular resistance caused by pathological conditions of the bronchi, lungs, thoracic cage, or pulmonary vessels, leading to pulmonary arterial hypertension. This condition is collectively known as cor pulmonale. The clinical manifestations of cor pulmonale generally develop slowly. Clinically, in addition to pulmonary and pleural symptoms, there gradually appear signs of pulmonary cardiac failure and damage to other organs. Common symptoms include coughing, expectoration, palpitations, dyspnea, fatigue, decreased endurance to physical activity. In the decompensated stage, symptoms such as worsening dyspnea, headaches, insomnia, decreased appetite, and even some signs of right heart failure like palpitations, poor appetite, abdominal bloating, nausea, and swelling of the lower limbs may occur.
What are the symptoms of pneumothorax?
Pneumothorax refers to the accumulation of air that occurs when air enters the pleural cavity, a closed space, which is known as pneumothorax. The most common clinical manifestations of pneumothorax depend on the speed of onset, the degree of lung compression, and the etiology of the primary disease causing the pneumothorax. Typically, patients may experience a high level of mental tension, fear, restlessness, shortness of breath, and a feeling of suffocation. Some individuals may sweat, have an increased pulse rate, with the most prominent symptom being difficulty in breathing. Additionally, some patients may experience coughing and chest pain, and some may develop mediastinal emphysema, leading to gradually worsening respiratory difficulties, and even manifestations of shock such as a drop in blood pressure.
Symptoms of Mycoplasma Pneumonia
Pneumonia caused by Mycoplasma pneumoniae infection, known as Mycoplasma pneumonia, refers to acute inflammation of the respiratory tract and lungs caused by Mycoplasma pneumoniae. It is usually accompanied by pharyngitis, bronchitis, and pneumonia. This type of pneumonia accounts for one third of non-infectious pneumonia cases and 10% of pneumonia cases caused by various reasons. Clinically, after infection with Mycoplasma pneumoniae, the symptoms usually appear gradually with a typical incubation period of two to three weeks. Some patients primarily experience fatigue, sore throat, headache, cough, and fever. Others may suffer from diarrhea, loss of appetite, muscle pain, and ear pain. The cough is generally paroxysmal and choking, with little sputum, and the fever can last two to three weeks. Some people may show extrapulmonary manifestations such as dermatitis. In children, complications such as periostitis or otitis media may occur, and there can be swelling of the cervical lymph nodes.
Can bronchiectasis be cured?
Bronchiectasis refers to the deformation and persistent dilation of the bronchi due to various inflammations and fibrosis in the patient's bronchi and surrounding lung tissue, which destroys the surrounding muscles and elastic tissues. Bronchiectasis is treatable, and usually, symptomatic treatment and fundamental treatment targeting the cause can be employed. Symptomatic treatment involves anti-infection treatment for infections caused by the dilation. If the patient produces a large amount of phlegm, treatments to facilitate expectoration can be given. Additionally, if the patient's dilated bronchi repeatedly cause coughing, expectoration, and hemoptysis, and if internal medical treatment is ineffective, part of the dilated bronchi can be surgically removed to achieve therapeutic goals.
What is acute respiratory failure?
Respiratory failure refers to the severe dysfunction in pulmonary ventilation and gas exchange in the respiratory system caused by various reasons under normal conditions. This dysfunction leads to ineffective gas exchange during respiration, resulting in hypoxia in the body and retention of carbon dioxide, thereby causing a series of physiological and metabolic disorders. Typically, under resting conditions at sea-level atmospheric pressure, respiratory failure is defined when arterial oxygen tension falls below 60 mmHg, accompanied by carbon dioxide retention, with carbon dioxide tension exceeding 50 mmHg, or without an increase in carbon dioxide tension. It is categorized into acute respiratory failure and chronic respiratory failure.
