Lung Sounds Audio Biography
(Source google.com)
Respiratory sounds, breath sounds, or lung sounds refer to the specific sounds generated by the movement of air through the respiratory system. These may be easily audible or identified through auscultation of the respiratory system through the lung fields. with a stethoscope. These include normal breath sounds and adventitious or "added" sounds such as crackles, wheezes, pleural friction rubs, stertor and stridor. Description and classification of the sounds usually involves auscultation of the inspiratory and expiratory phases of the breath cycle, noting both the pitch (typically described as low, medium or high) and intensity (soft, medium, loud or very loud) of the sounds heard. "Rhonchi" and "rales" are obsolete terminology whose use in the literature has been variable. The terms wheeze and crepitation have replaced them.
Crackles are the sounds you will hear in a lung field that has fluid in the small airways or if atelectasis is present. As stated before, crackles and rales are the same thing, and this can often lead to confusion among health care providers. Crackles come in two flavours: fine and coarse. Fine crackles sound like salt heated on a frying pan or the sound of rolling your hair between your fingers next to your ear. Coarse crackles sound like pouring water out of a bottle or like ripping open Velcro. This lung sound is often a sign of adult respiratory distress syndrome, early congestive heart failure, asthma, and pulmonary edema. Wheezes and rhonchi are actually very closely related. They are so closely related that the terminology for them has changed, too. Wheezes are now known as sibilant wheezes to distinguish them from rhonchi. Sibilant wheezes are high-pitched Stridor is an unusual sound that not many adult patients will have, but it bears mentioning. It is a high-pitched, musical sound that is heard over the upper airway. It usually indicated a foreign body obstruction of the larger airways, such as the trachea or a main bronchus, and requires immediate attention. It is also the most common type of breath sound heard in children with croup, though it is important to differentiate between croup and a foreign body airway obstruction. A pleural friction rub is caused by the inflammation of the visceral and parietal pleurae. These membranes are usually coated in a protective fluid, but when inflamed, and shrill sounding breath sounds that occur when the airway becomes narrowed. They often have a musical quality to them. These are the typical wheezes heard when listening to an asthmatic patient. Sibilant wheezes are caused by asthma, congestive heart failure, chronic bronchitis, and COPD. Stridor is an unusual sound that not many adult patients will have, but it bears mentioning. It is a high-pitched, musical sound that is heard over the upper airway. It usually indicated a foreign body obstruction of the larger airways, such as the trachea or a main bronchus, and requires immediate attention. It is also the most common type of breath sound heard in children with croup, though it is important to differentiate between croup and a foreign body airway obstruction.
A pleural friction rub is caused by the inflammation of the visceral and parietal pleurae. These membranes are usually coated in a protective fluid, but when inflamed, they stick together and make a sound like leather creaking against itself. It often causes a great deal of pain, and the patient will splint their chest and resist breathing deeply to help mitigate the pain. A pericardial rub and a pleural rub will often sound similar, and the best way to distinguish between the two is to make the patient hold their breath. If you still hear the rubbing sound, then the patient has a pericardial rub and requires different treatment. Pleural effusion and pneumothorax are two diagnoses that can cause a pleural friction rub.
