Part of the reason for that is that some of the language is interchangeable for instance, crackles and rales. Sonorous wheezes are named thusly because they have a snoring, gurgling quality to them, or similar to a low-pitched moan, more prominent on exhalation. Sonorous wheezes are caused by blockages to the main airways by mucous secretions, lesions or foreign bodies. Pneumonia, chronic bronchitis and cystic fibrosis are patient populations that commonly present with rhonchi.
Sibilant wheezes differ to sonorous wheezes as they are a higher-pitched, shrill, continuous whistling sound, occurring when the airway becomes obstructed and narrowed. These are the typical wheezes heard when listening to an asthmatic patient. Sibilant wheezes are caused by asthma, chronic bronchitis and obstructive pulmonary disease COPD. Crackles are also known as alveolar rales and are the sounds heard in a lung field that has fluid in the small airways. The sound crackles create are fine, short, high-pitched, intermittently crackling sounds.
The cause of crackles can be from air passing through fluid, pus or mucus. It is commonly heard in the bases of the lung lobes during inspiration. Stridor is caused by obstruction of the upper airway, is a sign of respiratory distress and thus requires immediate attention.
If adventitious sounds are heard, it is important to assess:. Explore this excellent resource! Rhonchi are discontinuous popping sounds heard during inspiration. True False. If the heart is not working correctly, the blood does not exit the lungs as quickly as it should.
This can cause fluid to build up, and it can pool in the lungs. Heart failure can affect both children and adults. Heart failure affects approximately 5. Beyond bibasilar crackles, symptoms may include swelling in the abdomen, coughing, and shortness of breath. Bronchitis involves inflammation of the bronchi, which are the tubes leading to the lungs. Bronchitis can be acute or chronic. Acute bronchitis often results from a virus, and it typically lasts for 3—10 days.
Pulmonary edema involves a buildup of fluid in the alveoli, which are small air sacs in the lungs. Pulmonary edema can result from altitude sickness, which occurs when a person unaccustomed to altitudes ascends to 2, meters or higher.
In addition to bibasilar crackles, symptoms of pulmonary edema include coughing, trouble breathing, blue-tinged lips, and spitting up pink, frothy mucus. Pulmonary fibrosis is a type of interstitial lung disease characterized by scarring of the lungs. In most cases, the underlying cause is unknown. However, pulmonary fibrosis can result from exposure to hazardous materials, such as radiation, animal droppings, and asbestos. A doctor can diagnose bibasilar crackles using lung auscultation, which involves listening to lungs sounds with a stethoscope.
Several characteristics can help a doctor to determine the cause of the crackles, including whether they occur when a person inhales or exhales. For example, crackles that occur late in the inspiratory phase when a person inhales may indicate heart failure or pneumonia.
Treatment for bibasilar crackles will depend on the underlying cause. The crackles may fade or disappear after treatment.
However, if the cause is a chronic condition, the crackles may occur on and off for an extended period. Answer: B. Crackles are heard when collapsed or stiff alveoli snap open, as in pulmonary fibrosis. Wheezes are commonly associated with asthma and diminished breath sounds with neuromuscular disease.
Breath sounds will be decreased or absent over the area of a pneumothorax. In this instance, it would be helpful to go through each clinical condition separately and predict what you may hear on auscultation.
