Rhonchus
Respiratory sounds, also known as lung sounds or breath sounds, refer to the specific sounds generated by the movement of air through the respiratory system. These may be easily audible or identified through auscultation of the respiratory system through the lung fields with a stethoscope as well as from the spectral characteristics of lung sounds. These include normal breath sounds and adventitious or "added" sounds such as crackles, wheezes, pleural friction rubs, stertor, and stridor. Description and classification of the sounds usually involve auscultation of the inspiratory and expiratory phases of the breath cycle, noting both the pitch (typically described as low (≤200 Hz), medium or high (≥400 Hz)) and intensity (soft, medium, loud or very loud) of the sounds heard. Normal breath sounds Normal breath sounds are classified as vesicular, bronchovesicular, bronchial or tracheal based on the anatomical location of auscultation. Normal breath sounds can also ...

Crackles
Crackles are the clicking, rattling, or crackling noises that may be made by one or both lungs of a human with a respiratory disease during inhalation. They are usually heard only with a stethoscope ("on auscultation"). Pulmonary crackles are abnormal breath sounds that were formerly referred to as rales. Bilateral crackles refers to the presence of crackles in both lungs. Basal crackles are crackles apparently originating in or near the base of the lung. Bibasal crackles refer to crackles at the bases of both the left and right lungs. Bilateral basal crackles also refers to the presence of ''basal'' crackles in both lungs. Crackles are caused by the "popping open" of small airways and alveoli collapsed by fluid, exudate, or lack of aeration during expiration. Crackles can be heard in patients with pneumonia, atelectasis, pulmonary fibrosis, acute bronchitis, bronchiectasis, acute respiratory distress syndrome (ARDS), interstitial lung disease or post thoracotomy or meta ...

Oedema
Edema, also spelled oedema, and also known as fluid retention, dropsy, hydropsy and swelling, is the build-up of fluid in the body's tissue. Most commonly, the legs or arms are affected. Symptoms may include skin which feels tight, the area may feel heavy, and joint stiffness. Other symptoms depend on the underlying cause. Causes may include venous insufficiency, heart failure, kidney problems, low protein levels, liver problems, deep vein thrombosis, infections, angioedema, certain medications, and lymphedema. It may also occur after prolonged sitting or standing and during menstruation or pregnancy. The condition is more concerning if it starts suddenly, or pain or shortness of breath is present. Treatment depends on the underlying cause. If the underlying mechanism involves sodium retention, decreased salt intake and a diuretic may be used. Elevating the legs and support stockings may be useful for edema of the legs. Older people are more commonly affected. The word is ...

Bronchophony
Bronchophony is the abnormal transmission of sounds from the lungs or bronchi. Bronchophony is a type of pectoriloquy. It is a general medical sign detected by auscultation. Technique The patient is requested to repeat a word several times while the provider auscultates symmetrical areas of each lung. The numbers "ninety-nine" or "sixty-six" are traditionally mentioned. The choice of "ninety-nine" is the result of a literal translation. The test was originally described by a German physician who used the phrase "neun und neunzig" (pronounced nɔʏnʊntˈnɔʏntsɪç, which he found would cause maximum vibration of the chest. The translation, "ninety-nine", has fewer vowels and is less effective in evoking the phenomenon. Better phrases in English include "toy boat”, "Scooby Doo", and “blue balloons".Whispered pectoriloquy Interpretation Normally, the sound of the patient's voice becomes less distinct as the auscultation moves peripherally; bronchophony is the phenomenon of ...

Egophony
Egophony (British English, aegophony) is an increased resonance of voice sounds heard when auscultating the lungs, often caused by lung consolidation and fibrosis. It is due to enhanced transmission of high-frequency sound across fluid, such as in abnormal lung tissue, with lower frequencies filtered out. It results in a high-pitched nasal or bleating quality in the affected person's voice. Technique While listening to the lungs with a stethoscope, the patient is asked to pronounce the modern English (more generally, post-Great Vowel Shift) long-E vowel sound. Interpretation Stethoscopic auscultation of a clear lung field during this articulation will detect a sound matching that received through normal hearing; that is, the sound articulated by the patient will be clearly transmitted through the lung field and heard unchanged by the clinician. When the lung field is consolidated (filled with liquid or other solid mass such as tumor or fungus ball), the patient's spoken English lo ...

Pectoriloquy
Pectoriloquy is the increased resonance of the voice through the lung structures, so that it is clearly comprehensible using a stethoscope on the chest. It usually indicates consolidation of the underlying lung parenchyma. Types include egophony and bronchophony. See also *Whispered pectoriloquy *Vocal fremitus Fremitus is a vibration transmitted through the body.

Pneumopericardium
Pneumopericardium is a medical condition where air enters the pericardial cavity. This condition has been recognized in preterm neonates, in which it is associated with severe lung pathology, after vigorous resuscitation, or in the presence of assisted ventilation. This is a serious complication, which if untreated may lead to cardiac tamponade and death. Pneumomediastinum, which is the presence of air in the mediastinum, may mimic and also coexist with pneumopericardium. It can be congenital, or introduced by a wound. Presentation The symptomatic patient may present with dyspnea, cyanosis, chest pain, pulsus paradoxus, bradycardia or tachycardia. Pathophysiology The mechanism responsible for pneumopericardium is the ‘Macklin effect’ – There is initially an increased pressure gradient between the alveoli and the interstitial space. Increased pressure leads to alveolar rupture, resulting in air getting through to the pericapillary interstitial pulmonary space. This spac ...

Pneumomediastinum
Pneumomediastinum (from Greek ''pneuma'' – "air", also known as mediastinal emphysema) is pneumatosis (abnormal presence of air or other gas) in the mediastinum, the central part of the chest cavity. First described in 1819 by René Laennec, the condition can result from physical trauma or other situations that lead to air escaping from the lungs, airways, or bowel into the chest cavity. In underwater divers it is usually the result of pulmonary barotrauma. Signs and symptoms The main symptom is usually severe central chest pain. Other symptoms include laboured breathing, voice distortion (as with helium) and subcutaneous emphysema, specifically affecting the face, neck, and chest. Pneumomediastinum can also be characterized by the shortness of breath that is typical of a respiratory system problem. It is often recognized on auscultation by a "crunching" sound timed with the cardiac cycle ( Hamman's crunch). Pneumomediastinum may also present with symptoms mimicking cardiac tamp ...

Hamman's Sign
Hamman's sign (rarely, Hammond's sign or Hammond's crunch) is a crunching, rasping sound, synchronous with the heartbeat, heard over the precordium in spontaneous mediastinal emphysema. It is felt to result from the heart beating against air-filled tissues. It is named after Johns Hopkins clinician Louis Hamman, M.D. This sound is heard best over the left lateral position. It has been described as a series of precordial crackles that correlate with the heart beat rather than respiration. Causes Hamman's crunch is caused by pneumomediastinum or pneumopericardium, and is associated with tracheobronchial injury. due to trauma, medical procedures (e.g., bronchoscopy) or rupture of a proximal pulmonary bleb. It can be seen with Boerhaave syndrome Esophageal rupture is a rupture of the esophageal wall. Iatrogenic causes account for approximately 56% of esophageal perforations, usually due to medical instrumentation such as an endoscopy or paraesophageal surgery. In contrast, th ...
