Rales: Small clicking, bubbling, or rattling sounds in the lungs. They are heard when a person inhales. They are believed to occur when air opens alveoli. Rales can also be described as moist, dry, fine, and coarse. [9] Rhonchi are coarse rattling respiratory sounds, usually caused by secretions in bronchial airways. The sounds resemble snoring.
Crackles are the clicking, rattling, or crackling noises that may be made by one or both lungs of a human with a respiratory disease during inhalation, and occasionally during exhalation. They are usually heard only with a stethoscope ("on auscultation ").
A death rattle is noisy breathing that often occurs in someone near death. [1] Accumulation of fluids such as saliva and bronchial secretions in the throat and upper airways is the cause. [ 2 ] Those who are dying may lose their ability to swallow and may have increased production of bronchial secretions, resulting in such an accumulation. [ 3 ]
Throughout the dying process, patients will lose the ability to tolerate their secretions, resulting in a sound often disturbing and emotionally distressing to visitors termed the death rattle. [2] However, the death rattle is a separate phenomenon from agonal respirations specifically related to the patient's inability to tolerate their ...
A respiratory examination, or lung examination, is performed as part of a physical examination, [1] in response to respiratory symptoms such as shortness of breath, ...
Bronchophony may be caused by a solidification of lung tissue around the bronchi – which may indicate lung cancer – or by fluid in the alveoli, which may indicate pneumonia. However, it may also have benign causes, such as wide bronchi. As such, it is usually an indication for further investigation rather than the main basis of a diagnosis.
Egophony (British English, aegophony) is an increased resonance of voice sounds [1] heard when auscultating the lungs, often caused by lung consolidation and fibrosis.It is due to enhanced transmission of high-frequency sound across fluid, such as in abnormal lung tissue, with lower frequencies filtered out.
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 ...
