[citation needed] The shortness of breath emphysema causes can increase over time and develop into chronic obstructive pulmonary disease. A sign of emphysema in smokers is a higher number of alveolar macrophages sampled from the bronchoalveolar lavage (BAL) in the lungs. The number can be four to six times greater in those who smoke than in non ...
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.

[18] [19] Abnormal sounds include: Wheezes, describing a continuous musical sound on expiration or inspiration. A wheeze is the result of narrowed airways. Common causes include asthma and emphysema. [20] Rhonchi (an increasingly obsolete term) characterised by low pitched, musical bubbly sounds heard on inspiration and expiration. Rhonchi are ...
Hamman's syndrome, also known as Macklin's syndrome, is a syndrome of spontaneous subcutaneous emphysema [1] (air in the subcutaneous tissues of the skin) and pneumomediastinum (air in the mediastinum, the center of the chest cavity), sometimes associated with pain and, less commonly, dyspnea (difficulty breathing), dysphonia, and a low-grade fever.
The three types of egressive sounds are pulmonic egressive (from the lungs), glottalic egressive (from the glottis), and lingual (velaric) egressive (from the tongue). The opposite of an egressive sound is an ingressive sound , in which the airstream flows inward through the mouth or nose.
Hamman's sign (rarely, Hammond's sign [1] or Hammond's crunch [2]) is a medical sign consisting of a crunching, rasping sound, synchronous with the heartbeat, [3] heard over the precordium in spontaneous mediastinal emphysema. It is thought to result from the heart beating against air-filled tissues.
Emphysema is a lung condition that causes shortness of breath and is caused by long-term exposure to airborne irritants including tobacco smoke, according to the Mayo Clinic. People who have ...
The three types of ingressive sounds are lingual ingressive or velaric ingressive (from the tongue and the velum), glottalic ingressive (from the glottis), and pulmonic ingressive (from the lungs). The opposite of an ingressive sound is an egressive sound, by which the air stream is created by pushing air out through the mouth or nose. The ...
