Chronic obstructive pulmonary disease (COPD) is a type of progressive lung disease characterized by chronic respiratory symptoms and airflow limitation. [8] GOLD 2024 defined COPD as a heterogeneous lung condition characterized by chronic respiratory symptoms (dyspnea or shortness of breath, cough, sputum production or exacerbations) due to abnormalities of the airways (bronchitis ...
A history of exposure to potential causes and evaluation of symptoms may help in revealing the cause the exacerbation, which helps in choosing the best treatment. A sputum culture can specify which strain is causing a bacterial AECB. [5] An early morning sample is preferred. [7] E-nose showed the ability to smell the cause of the exacerbation. [8]
Diagnosis of obstructive disease requires several factors depending on the exact disease being diagnosed. However one commonality between them is an FEV1/FVC ratio less than 0.7, i.e. the inability to exhale 70% of their breath within one second. [11] Following is an overview of the main obstructive lung diseases.
Place the bony parts of the palm around the borders of the patient's scapulae while he or she says "ninety-nine" or "one one one" to test for fremitus. Repeat the sequence on the front of the chest. A decrease in fremitus may be observed if the patient has a soft voice, obstructed bronchus, COPD , pneumothorax , or other disease or injuries ...
Pulmonary function testing is a safe procedure; however, there is cause for concern regarding untoward reactions and the value of the test data should be weighed against potential hazards. Some complications include dizziness, shortness of breath, coughing, pneumothorax, and inducing an asthma attack. [13] [14]
Lower respiratory infectious disease is the fifth-leading cause of death and the combined leading infectious cause of death, being responsible for 2.74 million deaths worldwide. [27] This is generally similar to estimates in the 2010 Global Burden of Disease study. [28]
Diffuse alveolar damage (DAD) is a histologic term used to describe specific changes that occur to the structure of the lungs during injury or disease.Most often DAD is described in association with the early stages of acute respiratory distress syndrome (). [1]
Diagnosis is generally based on symptoms. [1] Tests such as a chest X-ray or viral testing are not routinely needed, but may be used to rule out other diseases. [2] There is no specific medicine that is used to treat bronchiolitis. [3] [8] Symptomatic treatment at home is generally effective and most children do not require hospitalization. [1]
