An acute exacerbation of chronic obstructive pulmonary disease, or acute exacerbations of chronic bronchitis (AECB), is a sudden worsening of chronic obstructive pulmonary disease (COPD) symptoms including shortness of breath, quantity and color of phlegm that typically lasts for several days.
An acute exacerbation presents with increased shortness of breath and sputum production. [2] COPD is a risk factor for pneumonia; thus this condition should be ruled out. [2] In an acute exacerbation treatment is with a combination of anticholinergics, beta 2-adrenoceptor agonists, steroids and possibly positive pressure ventilation. [2]
Acute exacerbations of IPF (AE-IPF) are defined as an unexplained worsening or development of dyspnea within 30 days with new radiological infiltrates at HRCT abnormality often superimposed on a background consistent with UIP pattern. The yearly incidence of AE-IPF is between 10 and 15% of all patients.
While acute bronchitis often does not require antibiotic therapy, antibiotics can be given to patients with acute exacerbations of chronic bronchitis. [21] The indications for treatment are increased dyspnoea, and an increase in the volume or purulence of the sputum. [ 22 ]

[2] Asthma is caused by multiple genes , some having protective effect, with each gene having its own tendency to be influenced by the environment although a ...
Hyperacusis is an increased sensitivity to sound and a low tolerance for environmental noise. Definitions of hyperacusis can vary significantly; it often revolves around damage to or dysfunction of the stapes bone, stapedius muscle or tensor tympani ().
Respiratory sounds, also known as lung sounds or breath sounds, are the specific sounds generated by the movement of air through the respiratory system. [1] These may be easily audible or identified through auscultation of the respiratory system through the lung fields with a stethoscope as well as from the spectral characteristics of lung sounds. [2]
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 ...
