Side (additional) breathing sounds- these are wheezing, crepitus, pleural friction noise, pleuropericardial murmur, Hippocratic splash noise, the noise of a falling drop.

Wheezingarise in the trachea, bronchi and cavities. They are divided into dry and wet, and are heard in both phases of breathing. Dry wheezing. The cause of dry wheezing is narrowing of the lumen of the bronchi as a result of inflammatory edema of the mucous membrane or total spasm of the smooth muscles of the small bronchi (an attack of bronchial asthma), as well as the accumulation of viscous secretion in the bronchi, which can also narrow their lumen. All this leads to the fact that during breathing, air passes with a noise. Depending on where dry rales are formed, they are divided into sibilant, treble, high and bass, low, humming, humming. Whistling rales are formed in the case of narrowing of the small bronchi, bass - in the case of fluctuations of viscous sputum in the large bronchi. According to the English pulmonologist A. Forgach (1980), the occurrence of dry wheezing is based on the collapse of the walls of small bronchi as a result of increased intrathoracic pressure during exhalation (expiratory collapse of the bronchi); during the passage of air at different speeds through the formed slots, sounds like whistling and buzzing are generated. The height and timbre of dry wheezing depend not so much on the caliber of the bronchi as on the speed of the air stream. Dry rales can be heard over the entire surface of the lungs (bronchitis, bronchial asthma) or in a limited area, which is of more important diagnostic value (tuberculosis, tumors, scars, etc.). Sometimes dry wheezing can be heard at a distance or can be felt with the palm of your hand on your chest.

Wet rales are formed in the trachea, bronchi and lung cavities in the presence of liquid secretions (exudate, transudate, blood) in them. The passage of air through the liquid leads to the formation of bubbles, which float to the surface and burst. Moist wheezing is also called blistering.

Depending on the caliber of the bronchus, in which moist rales occur, there are fine bubbly (formed in small bronchi and bronchioles), medium bubbly (in the bronchi of medium size) and large-bubble(in large bronchi, cavities and large bronchiectasis) wheezing. Listening to large bubbling rales in the upper parts of the lungs, where there are no large bronchi, may indicate the presence of a cavity in the lungs (tuberculous cavity). Means of wheezing is usually heard if bronchitis develops. The presence of fine bubbling rales in a limited area may indicate a transition inflammatory process from the bronchioles to the alveoli (focal pneumonia).

Depending on the nature of the changes in the lungs, moist rales can be divided by sound quality into loud, sonorous (consonant) and dissonant (non-consonant). Voiced moist rales occur in the bronchi or cavities that are surrounded by compacted lung tissue, especially in smooth-walled cavities as a result of resonance in them. While listening to the sonorous rales, it seems as if they are formed close to the ear.

The appearance of ringing rales in the lower parts of the lungs may indicate inflammation of the lung tissue that surrounds the bronchi, and in the upper ones - the presence of a tuberculous infiltrate or cavity. In some cases, over large cavities against the background of amphoric breathing, voiced rales may have a metallic hue.

Unvoiced rales are heard in case of bronchitis, acute edema lungs (an unconsolidated lung drowns out the bursting of bubbles in the bronchi). After coughing, they can change (increase, decrease).

According to A. Forgach, the occurrence of moist rales is also due to the mechanisms of expiratory collapse: during exhalation, the walls of the bronchi close, and during inhalation they open, which is accompanied by the appearance of short sounds - "chips", which have a traditional name - wet rales. Based on the concept of A. Forgach, the American Association for Breast Diseases classifies all wheezing into "whistle" and "crackle" (rough, tender), which, in turn, are divided into inspiratory and expiratory.

Sometimes a sound is produced that resembles that of a falling drop. Such a phenomenon is heard over the cavity or pleural cavity, which contains fluid (usually pus), in case of a change in position, lying on a sitting position, when drops of liquid fall down and knock on the surface of purulent exudate.

Crepitus resembles a special crack, which occurs as a result of the separation of the glued walls of the alveoli during their filling with air at the moment of inhalation. Therefore, unlike wheezing, crepitus can be heard only at the height of inspiration. Crepitus is similar to the sound that occurs when a clump of hair is rubbed against the ear with the fingers. Basically, crepitation is observed in the presence of inflammation of the lung tissue, which is noted during the development of group pneumonia in the initial stage (crepitatio indux) and in the final, that is, the stage of resolution (crepitatio redux), as well as in the case of pulmonary infarction, compression atelectasis. If more secretions appear in the alveoli, crepitus may disappear.

Sometimes crepitus can be short-lived. For example, in people of advanced age, weakened after being in a lying position, during the first breaths (then disappears).

In patients with severe heart disease, so-called congestive crepitus can be heard on both sides of the lower lungs, and it is sometimes difficult to distinguish crepitus from small bubbling rales. It must be remembered that wheezing is heard on inhalation and exhalation, they are varied, change after coughing (sometimes they can disappear); crepitus is audible only at the height of inspiration, it is monotonous, constant (in case of inflammation), does not change after a cough.

Pleural rubbing noise. In healthy people, the sliding of the visceral layer of the pleura along the inner surface of the parietal layer occurs without any noise. Pleural friction noise occurs in the case of pleural inflammation (dry pleurisy), when it becomes covered with fibrin and its surface becomes uneven, rough, during the formation of infiltration cells, adhesions, cords, rashes, and also in case of excessive dryness of the pleura during dehydration , uremia). It resembles the crunch of snow or the sound that is generated when rubbing the back of the hand with a finger near the ear. The pleural friction noise is intermittent and is heard in both phases of breathing; best defined in places of significant excursion of the pulmonary edges (along the middle, posterior axillary and scapular lines). Depending on the nature of the pleural changes, the rubbing noise of the pleura can be tender or rough (sometimes it can be felt with the hand during palpation of the chest).

Pleural rubbing noise may resemble crepitus or wet wheezing. The following signs help to establish the nature of the noise:

1) after coughing, wheezing changes its character or disappears completely for a while, the pleural friction noise does not change

2) during pressing with a stethoscope on the chest, the pleural friction noise increases, wheezing does not change;

3) crepitus is heard only at the height of inspiration, the noise of pleural friction is heard both during inhalation and during exhalation;

4) if you close your mouth and pinch your nose, then during the retraction and protrusion of the abdomen, you can only hear the noise of friction of the pleura (as a result of the movements of the diaphragm, the pleural sheets begin to slide).

It must be remembered that the pleural friction noise is often accompanied by pain during breathing. In the case of significant pain, the patient can spare breathing, the pleural friction noise can weaken, disappear or acquire an intermittent nature (resembling saccadic breathing).

During the lesion of the pleura, which covers the mediastinum or lies close to the heart, the so-called pleuropericardial murmur. It can be heard not only during breathing, but also synchronously with the work of the heart (during systole and diastole).

Often the pleural friction noise disappears not only after recovery, but also if fluid or air appears in the pleural cavity. After the disappearance of fluid or air, the noise of pleural friction may occur again. In some cases, it can be noted for a long time.

Sometimes in patients with the simultaneous appearance of fluid and air in the pleural cavity (hydropneumothorax), you can hear the so-called splash noise in the chest ("The noise of the splash of Hippocrates"), first described by Hippocrates. To do this, you need to put your ear to the chest over the site of the hydropneumothorax and shake the patient. Sometimes the splashing noise can be felt by the patient himself (during a sharp change in body position).

The sound of a falling dropis also a symptom of hydro- or pyopneumothorax. This phenomenon is explained by the fall of a drop of liquid in the case of the patient's transition from a lying position to a sitting position.

Crepitus I Crepitation (crepitatio; lat. crepitare to creak, crunch)

crackling or crunching, detected by auscultation or palpation. Distinguish between alveolar, subcutaneous and bone crepitus.

Bone crepitus is a crunch that occurs by mutual friction of contacting bone fragments; comes to light, as in subcutaneous K., by palpation and auscultation. It is a specific symptom of a fracture, it is used to diagnose fractures during the examination of the victim on the spot (before X-ray examination). With complex injuries (for example, a combination of rib fracture with rupture of lung tissue), the simultaneous appearance of bone and subcutaneous crepitus is possible.

II Crepitation (crepitatio; lat. crepito creak, crunch)

a crunching or crackling sensation that occurs on palpation or auscultation.

Gas crepitation (page gasea; K. subcutaneous) - K. when palpating soft tissues or when pressing on them with the head of the phonendoscope, observed with subcutaneous emphysema.

Bone crepitation (page ossea) - K. when feeling the area of \u200b\u200bthe fracture in the early stages after, due to mutual friction of bone fragments.

Subcutaneous crepitation (c. subcutanea) - see Gas crepitation.

Crepitation of the pad (p. umbilici) - K. under the skin in the navel with perforation of the stomach or intestines in a patient with an umbilical hernia.

Tendon crepitus (S. tendinea) - K. in the area of \u200b\u200bthe synovial sheaths of the tendons, arising from movement; fibrinous tendovaginitis.

Wheezing in the lungs is an unhealthy breathing noise that comes from one or both lungs and is intermittent and of varying frequency. They are often caused by respiratory problems and can be felt on inhalation or exhalation, with or without coughing. A person may have more noticeable wet wheezing when lying down. This condition may be accompanied by a dry cough.

Pathological noises in the lungs in most cases can only be heard with a stethoscope during a physical examination. Therefore, you should not try to engage in self-diagnosis.

When wheezing occurs in both lungs, it is referred to as bilateral. And when they come from the base of the lung, they are known as basal or basal rales. In this case, wheezing is caused by a narrowing of the airways, the presence of contents in the alveoli, or a lack of aeration during exhalation.

Wheezing is common in people with respiratory conditions such as pneumonia, pulmonary fibrosis, bronchitis, and other conditions.

They are more common during inhalation than during exhalation. In most cases, wheezing is associated with inflammation and infection of the small bronchi, alveoli and bronchioles. If wheezing does not improve after coughing, it can sometimes also be a sign of pulmonary edema, a condition characterized by fluid in the alveoli due to heart failure.

Wheezing of the lungs can be roughly divided into weak, medium and strong. Weak wheezes can be soft, high-pitched, and very short. On the other hand, severe wheezing is louder, lower in sound and often lasts longer.

What do they mean?

Wheezing in the lungs is an abnormal murmur heard from one or both lungs. Most form at the base of the lungs and can only be heard with a stethoscope. They usually reflect the accumulation of mucus, pus, or fluid in the airways and lungs.

Wheezing often means respiratory diseasessuch as pneumonia, bronchitis and others. They can also indicate a serious heart condition that causes an accumulation or blockage of blood flow between the heart and lungs.

This symptom is serious enough and can become dangerous to health and life, urgent medical diagnosis, taking into account medical history, blood tests and x-rays may be required to identify and treat its underlying cause.

In medical terminology

In fact, such a concept as "wheezing in the lungs" (English "rhonchi", "rales") in medicine in most of Europe, North America and Australia has not been considered suitable for decades for describing auscultation of the chest. The main reason was the confusion of its application in the medical literature. More appropriate now are terms such as crepitus of the lungs, wheezing, pleural friction noise.

Therefore, this article should not be considered as a guide for medical professionals... In it, some of the terminology is not very accurate or does not apply to domestic medicine (taken from the English-language medical literature). But this made it possible to make the article more understandable and simpler.

What are they?

Wheezing in the lungs can be divided into four types, all of which can help diagnose what may be the underlying cause. These types are:

  • Wheezing or crepitus of the lungs (rales)which can be described as rumbling, gurgling, or bubbling sounds, more often at the end of inhalation.
  • Sibilant wheezes - high-pitched dry sounds from the airways when they are narrowed. The sounds are so high that they can be heard without a stethoscope.
  • Creaking (stridor) - whistling-like, resulting from narrowing or blockage of the upper airways.
  • Dry (rhonchi) - harsh rattling respiratory sounds, usually caused by secretions in the bronchial airways. Usually heard more strongly during exhalation.

Please note that the Russian translation of this classification is very approximate. English variants of names in brackets are more correct.

The description is also found separately pleural friction sound... This is a skin-like sound that is often accompanied by severe pain that interferes with breathing. Normally, the pleura is covered with protective mucus, but with inflammation, this membrane can stick together, then a characteristic sound arises on auscultation (listening).

Wheezing and dry cough

A dry cough is a cough that is not accompanied by the production of phlegm (a viscous substance secreted by the mucous membrane of the respiratory tract in excess with a cold).

A dry cough with wheezing in the lungs can be a symptom of a variety of health problems. For some people, this can be the result of environmental irritations such as allergies or the inhalation of very dry, heated air.

If a dry cough becomes chronic, it could be a sign of other conditions, such as the flu, whooping cough, a viral infection, or a side effect of taking heart medications.

Wheezing on exhalation

The sound in the lungs when you exhale in English is often popularly described as "death rattle". However, this can be caused by various conditions, some of which are harmless. Although it is more normal to have it while inhaling than exhaling.

Exhalation wheezing can be a sign of pneumonia, blockage, or fluid accumulation in the lungs. On the other hand, while inhaling, they can be a sign of asthma, bronchitis, or other causes.

An urgent medical diagnosis may be required to determine what the underlying cause may be. You should see your doctor as soon as you notice such a noise coming from both or one of your lungs.

Wheezing when lying down

As mentioned, light wheezing sounds can only be heard with a stethoscope during a medical examination. However, some cases can be so severe that they can be heard even without this instrument.

Wheezing in the lungs while lying down may indicate a blockage of the nasal passages and airways with mucus. During this time, the lungs are under increased pressure, they collapse over time, causing a condition known as atelectasis.

In such cases, other symptoms may occur, such as shortness of breath, chest pain, shortness of breath, cough, and a feeling of choking. If any of these signs are present, you should seek emergency medical attention.

The reasons

1. Bronchitis

Bronchitis is an inflammation of the bronchi. Most people develop acute bronchitis after a cold. This often happens in a day or two, depending on how strong the body's immune system is.

Chronic bronchitis does not go away without medical care... Common symptoms include coughing, wheezing, fatigue, shortness of breath, and chills. A doctor should be consulted if any of these symptoms persist for a long time.

2. Obstructive pulmonary disease

This is a serious condition that requires treatment as soon as possible. Obstructive pulmonary disease, such as asthma or cystic fibrosis, can cause wheezing and wheezing. If left untreated, it can lead to more serious conditions such as bronchiectasis.

These illnesses affect breathing and can cause carbon dioxide and fluids to build up inside the lung. The continuous build-up of these products can lead to scarring, which can be manifested by airway noises.

3. Interstitial lung disease

This disease is associated with air sacs and tissues in the lungs. It includes conditions such as sarcoidosis and rheumatoid arthritis. These conditions are known to cause scarring in the lungs where fluid accumulates, causing wheezing.

4. Heart failure

Heart failure, caused by a weakened heart muscle, a viral infection, or a genetic disorder, can also cause lung sounds. Because the function of the heart is impaired, there is increased pressure in the arteries between the heart and the lungs, which can lead to leakage of blood into the lungs.

5. Pneumonia

Pneumonia is an infection that causes inflammation in one or both lungs (unilateral or bilateral). When pneumonia is the cause of wheezing, it is usually heat, cough, tiredness, headache and severe pain in the chest.

Antibiotics can be used to treat bacterial pneumonia, according to the Mayo Clinic. Aspirin and ibuprofen can be used to relieve chest pain. It is recommended that you see your doctor for proper treatment and diagnosis.

6. Pulmonary edema

Pulmonary edema is caused by the presence of excess fluid in them, which accumulates in the air sac, making it difficult to breathe. Common cause Fluid buildup is a heart problem, but it can also be caused by other causes, such as pneumonia, chest trauma, and exposure to certain toxins.

7. Pulmonary fibrosis

Pulmonary fibrosis occurs due to scarring of the lungs (usually after inflammation). This condition can manifest as shortness of breath, chest discomfort and fatigue. Steroids and natural amino acids can be used to treat this problem.

Other treatment options include oxygen therapy, lung rehabilitation, and breathing support. In severe cases, a surgical procedure can be used to remove fibroids and other symptoms.

8. Atelectasis

Atelectasis occurs when part of the lung collapses. This makes it difficult to inhale and exhale. Atelectasis can result from trauma or an underlying lung infection.

Treatment for this condition must begin at early stage... It will unblock the airways, helping to open the collapsed lung.

9. Asthma

Asthma is a respiratory disorder that causes the airways to swell and produce more mucus. This disease is characterized by wheezing, shortness of breath, and coughing.

An inhaler may be used to relieve asthma symptoms such as coughing, wheezing, and shortness of breath.

10. Lung infection

A viral infection in the lungs can also lead to noise, shortness of breath, and coughing due to blockages, irritation, and inflammation of the airways.

A wheezing sound can be a result of the accumulation of fluids, mucus, inside the lungs. With a lung infection, sounds are often heard even without a stethoscope.

Treatment

Treatment can vary depending on what is the underlying cause. When diagnosing a condition, the doctor uses a stethoscope to listen for breathing. Although rare, in severe cases, wheezing can sometimes be heard without a stethoscope.

To confirm the diagnosis, the doctor may need to order a chest x-ray, blood test, sputum test, or an electrocardiogram to check for heart problems. The cessation of wheezing is associated with the elimination of the underlying cause.

When the reason is chronic diseases the lungs, you need to make some lifestyle changes in addition to the prescribed medication to control your symptoms. This applies to people who smoke. A common treatment option may include:

  • Using inhaled steroids to reduce inflammation
  • Oxygen therapy helps make breathing easier
  • Using a bronchodilator to relax and open up blocked airways.

Folk remedies

When a problem is accompanied by other symptoms, such as back pain, shortness of breath, or a runny nose, there are some effective home remedies that can be used to relieve some of these symptoms. If symptoms persist, the underlying cause should be diagnosed and treated as soon as possible.

1. Steam inhalation

Inhalation is one of the best methods to use in this case. Moisture and heat will help break down and dissolve mucus that is blocking your airways.

  • Take a basin or bowl of hot water
  • Add a few drops of eucalyptus oil
  • Bend over the container and cover with a dry towel so as not to lose heat or moisture
  • Carry out the procedure until relief is felt.

Ginger is a great remedy to try when treating respiratory problems. In addition to strengthening the immune system to speed up healing, it has anti-inflammatory properties and polyphenols that can help inhibit mucus production.

  • Sound phenomena arising in connection with the act of breathing are called breathing noises. Distinguish between main and additional, or side, breathing sounds. The main breathing sounds are vesicular, bronchial and hard breathing. Additional (side) noises include wheezing, crepitus and pleural friction noise. caused by their spasm and mucosal edema. They are most typical for an attack of bronchial asthma.

    Crepitation ("crepitare" - creak, crunch) - collateral respiratory noise, which is formed when the walls of the alveoli, which are more humid than usual, have lost their elasticity, which are heard exclusively at the height of inspiration as a short sound "flash" or "explosion". It resembles the sound produced by kneading a bundle of hair near the ear with your fingers. Usually crepitus is a sign of croupous pneumonia, accompanying the phases of appearance and resorption of exudate; can occasionally be heard at the very beginning of the development of pulmonary edema .. Unlike wheezing, crepitus occurs not in the bronchi, but in the alveoli, when there is exudate in them. It is a very important diagnostic sign that indicates damage to the pulmonary parenchyma itself. Crepitation (crepitus - crackle). Unlike wheezing, crepitus does not occur in the bronchi, but in the alveoli, when there is exudate in them. It is a very important diagnostic sign that indicates damage to the pulmonary parenchyma itself. This sound can be compared to that heard when a strand of hair is rubbed over the ear.

    The mechanism of crepitation is as follows: if there is exudate in the alveoli, their walls stick together during exhalation, with subsequent inhalation they break apart and give a sound phenomenon at the height of inhalation, which is called crepitation, that is, it is the sound of the sticking together walls of the alveoli ... Distinguishing Crepitus from Other Adverse Respiratory Noises... Crepitation is sometimes incorrectly referred to as crepitant or sub-crepitant rales. This is not true, since these auscultatory phenomena are different both in the mechanism of their origin and in auscultatory characteristics. So, crepitus is heard only at the inspiratory height, while wet rales - in both phases. After coughing, wheezing changes, may disappear, but crepitus does not change. Crepitation occurs in alveoli of uniform size and is the same in its caliber (one-caliber), more monotonous, while wheezing is formed in the bronchi of different calibers and, therefore, are of different caliber. Crepitation appears as an explosion, instantly, while wheezing is more prolonged in time. In the listening area, crepitus is always more than wheezing, because there are more alveoli than wheezing in a given acoustic sphere .

    Clinical significance... The appearance of crepitus is very characteristic of croupous pneumonia. Sometimes crepitus is heard in elderly people without lung pathology, if they were in a horizontal position or with very shallow breathing, and physiological atelectasis occurs. During the first deep breaths, the alveoli, which are in a collapsed state, are straightened and transient crepitus is heard. This is a very common occurrence in the elderly, weak and bedridden patients.
