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.
Rhonchi are the result of viscous fluid in the airways. [21] Crackles or rales. Intermittent, non-musical and brief sounds heard during inspiration only. They may be described as fine (soft, high-pitched) or coarse (louder, low-pitched). These are the result of alveoli opening due to increased air pressure during inspiration.
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"). Pulmonary crackles are abnormal breath sounds that were formerly referred to as rales. [2]
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.
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.
Percussion of the lung fields for dullness or hyper-resonance. Auscultation (with a stethoscope) of the lung fields for diminished or unusual breath sounds. Rales or rhonchi heard over lung fields with a stethoscope. As many heart diseases can give pulmonary signs, [20] a thorough cardiac investigation is usually included.
Steelers' George Pickens Makes Stunning Remark After Playoff Loss Vs Ravens. Read On The Fox News App. NFL fans were not happy with the lack of a penalty, especially in such a crucial spot.
Usually spoken sounds of a whispered volume by the patient would not be heard by the clinician auscultating a lung field with a stethoscope. However, in areas of the lung where there is lung consolidation, these whispered spoken sounds by the patient (such as saying 'ninety-nine') will be clearly heard through the stethoscope. This increase in ...
