Timing and Intensity Crackles heard only at the end of inspiration are called fine crackles. When the surfactant is depleted, the alveoli collapse. Air enters the alveoli at the end of inspiration. This sound is generated as the alveoli pop open from it’s collapsed state.

Is rhonchi heard on inspiration or expiration?
Rhonchi are typically heard during expiration while rales are heard on inspiration. Rhonchi may briefly disappear after coughing (or suctioning mucus secretions) while this typically has no or little effect on rales.
What are crackles and rhonchi?
Rhonchi are caused by blockages to the main airways by mucous, lesions, or foreign bodies. Pneumonia, chronic bronchitis, and cystic fibrosis are patient populations that commonly present with rhonchi. Coughing can sometimes clear this breath sound and make it change to a different sound. Crackles (Rales)
What are the 3 normal breath sounds?
Normal breath sounds are classified as tracheal, bronchial, bronchovesicular, and vesicular sounds. Normal Breath Sounds
- duration (how long the sound lasts),
- intensity (how loud the sound is),
- pitch (how high or low the sound is), and.
- timing (when the sound occurs in the respiratory cycle).
Where are Bronchovesicular sounds heard?
Bronchovesicular breath sounds are best heard between the first and second intercostal spaces of the anterior chest. Bronchial sounds are best heard over the body of the sternum.
Is wheezing heard on inspiration or expiration?
Wheezes are heard more commonly during expiration because the airways normally narrow during this phase of respiration. Wheezing during expiration alone is generally indicative of milder obstruction than if present during both inspiration and expiration, which suggests more severe airway narrowing.
What is Crepitation sound?
Crepitation refers to situations where noises are produced by the rubbing of parts one against the other, as in: Crepitus, a crunching sensation felt in certain medical problems. Rales or crackles, abnormal sounds heard over the lungs with a stethoscope. A mechanism of sound production in grasshoppers during flight.
What is the difference between rales and crackles?
Rales are a higher-pitched sound sometimes called crackles or bibasilar crackles. The terms rales or crackles have been used interchangeably and are usually a matter of preference, not a difference in the condition. These sounds are formed when air moves into closed spaces.
What is an adventitious sound?
Adventitious sounds refer to sounds that are heard in addition to the expected breath sounds mentioned above. The most commonly heard adventitious sounds include crackles, rhonchi, and wheezes. Stridor and rubs will also be discussed here.
What’s a stridor?
Stridor is a noisy or high-pitched sound with breathing. It is a sign that the upper airway is partially blocked. It may involve the nose, mouth, sinuses, voice box (larynx), or windpipe (trachea).
What are the different types of breath sounds?
The 4 most common are:
- Rales. Small clicking, bubbling, or rattling sounds in the lungs. They are heard when a person breathes in (inhales).
- Rhonchi. Sounds that resemble snoring.
- Stridor. Wheeze-like sound heard when a person breathes.
- Wheezing. High-pitched sounds produced by narrowed airways.
What does COPD auscultation sound like?
Rhonchi are continuous low pitched, rattling lung sounds that often resemble snoring. Obstruction or secretions in larger airways are frequent causes of rhonchi. They can be heard in patients with chronic obstructive pulmonary disease (COPD), bronchiectasis, pneumonia, chronic bronchitis, or cystic fibrosis.
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 are tubular breath sounds?
Bronchial sounds, or “tubular sounds,” are the type of sounds that a person may make while breathing. Bronchial sounds are loud and harsh with a midrange pitch and intensity. A doctor will use a stethoscope to listen for sounds. They typically emanate from the following areas: the larynx, or voice box.
What are BV sounds?
Vesicular breath sounds are a type of lung sound that doctors can hear over most areas of the chest. They occur when air rushes in and out of the lungs during breathing. Normally, vesicular breath sounds are: soft.
What are the breath sounds heard of the trachea?
The bronchial breath sounds over the trachea has a higher pitch, louder, inspiration and expiration are equal and there is a pause between inspiration and expiration. The vesicular breathing is heard over the thorax, lower pitched and softer than bronchial breathing.
