Acute bronchitis, also known as a chest cold, is short-term bronchitis – inflammation of the bronchi (large and medium-sized airways) of the lungs. [2] [1] The most common symptom is a cough. [1] Other symptoms include coughing up mucus, wheezing, shortness of breath, fever, and chest discomfort. [2] The infection may last from a few to ten ...
Acute bronchitis, also known as a chest cold, is a short-term inflammation of the bronchi of the lungs. [4] [6] The most common symptom is a cough that may or may not produce sputum. [4] [19] Other symptoms may include coughing up mucus, wheezing, shortness of breath, fever, and chest discomfort. [6] Fever when present is mild. [20]
A wheeze is a clinical symptom of a continuous, coarse, whistling sound produced in the respiratory airways during breathing. [1] For wheezes to occur, part of the respiratory tree must be narrowed or obstructed (for example narrowing of the lower respiratory tract in an asthmatic attack), or airflow velocity within the respiratory tree must be heightened.
Lower respiratory tract infection (LRTI) is a term often used as a synonym for pneumonia but can also be applied to other types of infection including lung abscess and acute bronchitis. Symptoms include shortness of breath, weakness, fever, coughing and fatigue. [3]
When the airways spasm or constrict in response to the irritating stimulus of the breathing tube, it is difficult to maintain the airway and the patient can become apneic. During general anesthesia, signs of bronchospasm include wheezing, high peak inspiratory pressures, increased intrinsic PEEP , decreased expiratory tidal volumes, and an ...
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]
Shortness of breath and wheezing are present in many cases. [5] Exacerbations may be accompanied by increased amount of cough and sputum productions, and a change in appearance of sputum. [citation needed] An abrupt worsening in COPD symptoms may cause rupture of the airways in the lungs, which in turn may cause a spontaneous pneumothorax. [4]
The flow of air into and out of the lungs is impaired. [6] This can be measured with breathing devices such as a peak flow meter or by spirometry. Most people with COPD have characteristics of emphysema and chronic bronchitis to varying degrees.
