Rhonchi are continuous, low-pitched, snoring or gurgling sounds heard in the lungs, caused by air moving through large airways partially blocked by mucus, secretions, or other obstructions, often clearing or changing after a cough, and indicating conditions like bronchitis, pneumonia, or COPD.
Rhonchi (plural of the word rhonchus) are continuous, low-pitched sounds that are best heard when you're breathing out (also called “expiration”). The sound might move around to different parts of your chest when you cough, moving mucus around. The sound is sometimes described as snoring or gurgling.
Patients with rhonchi may experience symptoms such as shortness of breath, coughing, wheezing, and chest discomfort. These symptoms can range from mild to severe, depending on the underlying cause and extent of airway obstruction. For patients, the most immediate effect of rhonchi is impaired breathing.
Rhonchi Lung Sounds
These sounds happen because your larger airways are narrowed by mucus, and they flutter as air flows through. Wheezing and rhonchi have a similar cause (narrowed airways usually due to fluid buildup), so the causes are mostly the same. For instance, rhonchi is often caused by: Pneumonia.
Does it matter? Even though all three of these lung sounds can be caused by some of the same conditions, it is important to distinguish among them. Wheezing suggests narrowed airways, rales suggest fluid in the lungs, and rhonchi are a sign of obstruction of the bronchi.
Your doctor will listen to your lungs with a stethoscope. If you have pneumonia, your lungs may make crackling, bubbling, and rumbling sounds when you inhale.
Wheezing. High-pitched sounds produced by narrowed airways. They are most often heard when a person breathes out (exhales). Wheezing and other abnormal sounds can sometimes be heard without a stethoscope.
Crackles are defined as discrete sounds that last less than 250 ms, while the continuous sounds (rhonchi and wheezes) last approximately 250 ms. Rhonchi are usually caused by a stricture or blockage in the upper airway.
Sonorous Wheezes (Rhonchi)
What were once called 'rhonchi' are now mostly referred to as sonorous wheezes (though the terms are still used interchangeably). Sonorous wheezes are named thusly because they have a snoring, gurgling quality to them or are similar to a low-pitched moan, more prominent on exhalation.
It is the long-term inflammation in the bronchi. Its options for treatment include smoking cessation, inhalers, oxygen tanks, steroids, or surgery.
Crackles are the result of fluid-filled air sacs. Fine or high-pitched crackles sound like rubbing hair between your fingers. Coarse or low-pitched crackling sounds like velcro pulled apart. Crackles can be caused by any inflammation of the lungs, such as asthma, pneumonia, bronchitis, and emphysema.
Bronchitis in and of itself is not contagious – but the viruses that cause bronchitis are. The viruses can be contagious through the respiratory droplets of the infected person, and can spread when the infected person coughs, sneezes or talks. If you inhale these droplets, you can get sick with a virus.
Diagnosing bronchitis
Your health care provider will listen to your chest with a stethoscope to try to detect wheezing and sounds of airways clogged with mucous called rhonchi.
Rhonchi are a feature of obstructive lung disease. Symptoms develop when there is either an acute flare-up of the disease (known as an exacerbation) or the onset of interstitial pneumonia.
Mild wheezing that occurs along with symptoms of a cold or upper respiratory infection does not always need to be treated. See a healthcare professional if you don't know why you're wheezing, your wheezing keeps coming back or it happens along with any of these symptoms: Trouble breathing. Rapid breathing.
The Distinctive Characteristics of COPD Lung Sounds
Wheezes, for example, are high-pitched musical sounds that occur during exhalation when narrowed airways create turbulence. Crackles, on the other hand, are intermittent popping or rattling noises that indicate the presence of fluid or mucus in the airways.
Both types of pneumonia can have similar symptoms, including: cough, fever and chills, fatigue, chest tightness and shortness of breath. But while viral pneumonia often has a gradual onset, bacterial pneumonia can often present with sudden and severe symptoms, including high fever and a productive cough.
In his chapter on lobar pneumonia, the quintessential physician and educator, Sir William Osler, wrote 'Pneumonia may well be called the friend of the aged. Taken off by it an acute, short, not often painless illness, the old man escapes those “cold gradations of decay” so distressing to himself and to his friends.
Rhonchi Definition
They can be heard in patients with chronic obstructive pulmonary disease (COPD), bronchiectasis, pneumonia, chronic bronchitis, or cystic fibrosis. Rhonchi usually clear after coughing.
Rhonchi can be caused by pneumonia, cystic fibrosis, or COPD. Treatments usually consist of specific medications, lung therapies, and surgeries.
Rhonchi are low-pitched, snoring sounds caused by airway blockage. In CHF patients, these sounds happen during breathing in and out. They show a lot of fluid in the airways.
Symptoms of bacterial pneumonia
High fever (up to 105 F or 40.55 C). Cough with yellow, green or bloody mucus. Tiredness (fatigue). Rapid breathing.
