crackles (fine) a common, abnormal respiratory sound consisting of discontinuous bubbling noises heard on auscultation of the chest during inspiration; this sound has a popping sound produced by air entering the distal bronchioles or alveoli that contain serous secretions.

What is a discontinuous breath sound?
Crackles are referred to as discontinuous sounds; they are intermittent, nonmusical and brief. Crackles may be heard on inspiration or expiration. The popping sounds produced are created when air is forced through respiratory passages that are narrowed by fluid, mucus, or pus.
What is the name of a bubbling sound in lungs?
Rales. Small clicking, bubbling, or rattling sounds in the lungs. They are heard when a person breathes in (inhales).
What is a rhonchi?
This is a low-pitched sound that resembles snoring. Wheezing. This is a high-pitched sound, almost like a long squeak, that can occur as you inhale or exhale. Stridor.
What are abnormal breath sounds called?
Adventitious sounds are the medical term for respiratory noises beyond that of normal breath sounds. The sounds may occur continuously or intermittently and can include crackles, rhonchi, and wheezes.
Are crackles heard on inspiration or expiration?
A wheeze is high-pitched continuous musical sound, which may occur during inspiration and/or expiration, due to an obstructive process. Crackles are typically heard during inspiration and can be further defined as coarse or fine. Coarse crackles are heard during early inspiration and sound harsh or moist.
What does stridor sound like?
Stridor is a high-pitched squeaking or whistling sound, usually due to an obstruction in an airway. Stridor is a sign of an underlying health issue rather than a diagnosis or disease in itself.
What is crackling sound in chest?
Crackles occur if the small air sacs in the lungs fill with fluid and there’s any air movement in the sacs, such as when you’re breathing. The air sacs fill with fluid when a person has pneumonia or heart failure. Wheezing occurs when the bronchial tubes become inflamed and narrowed.
Where are crackles heard in the lungs?
Crackles (Rales) 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.
What is crackling in the lungs?
Bibasilar crackles are a bubbling or crackling sound originating from the base of the lungs. They may occur when the lungs inflate or deflate. They’re usually brief, and may be described as sounding wet or dry. Excess fluid in the airways causes these sounds.
What is vocal Fremitus?
Vocal fremitus is a vibration transmitted through the body. It refers to the assessment of the lungs by either the vibration intensity felt on the chest wall (tactile fremitus) and/or heard by a stethoscope on the chest wall with certain spoken words (vocal resonance).
What is Weezing?
Wheezing is a high-pitched whistling sound made while you breathe. It’s heard most clearly when you exhale, but in severe cases, it can be heard when you inhale. It’s caused by narrowed airways or inflammation. Wheezing may be a symptom of a serious breathing problem that requires diagnosis and treatment.
What happens inspiration?
The first phase is called inspiration, or inhaling. When the lungs inhale, the diaphragm contracts and pulls downward. At the same time, the muscles between the ribs contract and pull upward. This increases the size of the thoracic cavity and decreases the pressure inside.
What causes stridor?
Stridor is a high-pitched sound that is usually heard best when your child breathes in (known as “inspiration”). It’s usually caused by an obstruction or narrowing in your child’s upper airway.
What causes crackles in breath sounds?
Crackles (rales) are caused by excessive fluid (secretions) in the airways. It is caused by either an exudate or a transudate. Exudate is due to lung infection e.g pneumonia while transudate such as congestive heart failure.
