They can be auscultated over the trachea and anteriorly along each side of the sternum, from the second to fourth intercostal spaces. Bronchial lung sounds: loud and high-pitched Tracheal lung sounds: harsh, like air in a pipe Bronchovesicular lung sounds: softer than bronchial sounds with a tubular quality Vesicular lung sounds: soft, blowing, or rustling Where to listen to lung sounds. In contrast, bronchial breath sounds are heard over a dense, airless lower lobe only when the bronchi are patent, because sound isn’t transmitted directly to the airless lower lobe tissues. Bronchial breath sounds are hollow, tubular sounds that are higher-pitched compared to vesicular sounds. Bronchial breath sounds are heard over a dense, airless upper lobe, even without a patent bronchus (♦Sound 60), because the upper lobe surfaces are in direct contact with the trachea and loud tracheal breath sounds are transmitted directly to the dense, airless upper lobe tissues. Present, decreased chest wall movement and a dull percussion note are apparent over the affected area. This happens because little high-frequency sound is lost through attenuation or filtration. Clinical findings vary, depending on the location of the consolidated area and the causative agent. When lung tissue between the central airways and the chest wall becomes airless because of conditions that increase lung density, transmission of breath sounds from large airways is enhanced. A forced expiratory wheeze (FEW) may be an early sign of airway obstruction in patients with bronchial asthma.

The sounds of bronchial breathing are heard almost unchanged since they are transmitted to the stethoscope by the nonaerated tissue of collapsed or consolidated lung. In this condition, fluid, leukocytes, and erythrocytes accumulate in spaces that are normally air-filled, producing a consolidated area. Bronchoprovocation studies have also disclosed that wheezing may not be as sensitive as changes in basic lung sounds in acute airway narrowing. Bronchial breathing and its close associates tracheal and tubular breathing represent the normal sounds of air flowing back and forth through the bronchial tree. This documentation indicates that the expected sound (vesicular) was heard, specifies where it was heard (majority of the lung fields), notes the absence of any additional (adventitious) sounds, and explicitly mentions some of the specific sounds you listened for but did not hear (wheezing, crackles, rhonchi, stridor).The most common cause of lung tissue consolidation (solidification) is pneumonia, a lung inflammation that can be caused by bacteria, viruses, or chemical insults (such as with aspiration). No wheezing, crackles, rhonchi, or stridor.” “Normal vesicular breath sounds heard over the majority of the lung fields. This means that you heard the expected breath sounds and there were no abnormal or extra sounds. You will learn about the anatomy of the lung along with landmarks for lung auscultation. Lung auscultation is an important medical skill that EMTs and paramedics should be familiar with. If lung sounds are normal, they’re often described as “clear to auscultation bilaterally” or “CTAB” (an abbreviation of the same phrase). This guide to auscultating lung sounds will cover everything emergency medical technicians (EMT) need to know about assessing a patient’s breath sounds. When charting normal lung sounds, it’s important to be concise, clear, and descriptive. Vesicular lung sounds: over most lung spacesĬharting normal lung sounds: how to document lung sounds.
