Respirology. 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 ...
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.
Exhalation (or expiration) is the flow of the breath out of an organism. In animals, it is the movement of air from the lungs out of the airways, to the external environment during breathing . This happens due to elastic properties of the lungs, as well as the internal intercostal muscles which lower the rib cage and decrease thoracic volume.
Breathing ( spiration [1] or ventilation) is the rhythmical process of moving air into ( inhalation) and out of ( exhalation) the lungs to facilitate gas exchange with the internal environment, mostly to flush out carbon dioxide and bring in oxygen .
Causes. virus, bacteria, common cold, allergy, pneumonia, asthma, tuberculosis. 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 ...
Pulse pressure is quantified using a blood pressure cuff and stethoscope (Korotkoff sounds), by measuring the variation of the systolic pressure during expiration and inspiration. To measure the pulsus paradoxus, place a blood pressure cuff on the patient's arm and very slowly deflate the cuff while listening for brachial pulsations.
First heart sound: caused by atrioventricular valves – Mitral (M) and Tricuspid (T). Second heart sound caused by semilunar valves – Aortic (A) and Pulmonary/Pulmonic (P). Heart sounds are the noises generated by the beating heart and the resultant flow of blood through it. Specifically, the sounds reflect the turbulence created when the ...
The “cooing” sounds softer and lower pitched than the wheezing or exhalation sounds that researchers identified as byproducts of the animal’s breathing.
