Egophony (British English, aegophony) is an increased resonance of voice sounds [1] 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.
Vocal resonance is increased. Here, the patient's voice (or whisper, as in whispered pectoriloquy) can be heard more clearly when there is consolidation, as opposed to the healthy lung where speech sounds muffled. A pleural rub may be present. [4] A lower P A O 2 than calculated in the alveolar gas equation
In UK bronchophony is often called "vocal resonance" and is similar to "tactile vocal fremitus" (TVF); the difference being that in TVF the sensor is the edge of the hand. All three - whispering pectoriloquy, TVF and vocal resonance - fulfill the same purpose, to distinguish between consolidation and pleural effusion, both of which cause ...
A clinician auscultating the posterior lung of a patient. Pectoriloquy, egophony and bronchophony are tests of auscultation that utilize the phenomenon of vocal resonance. [3] Clinicians can utilize these tests during a physical exam to screen for pathological lung disease.
Signs and symptoms of white lung pneumonia can vary based on what caused the illness in the first place, Dr. Ganjian says. However, these are the most common pneumonia symptoms, according to the ...
Resonance: Loud and low pitched. Normal lung sound. [15] Dullness: Medium intensity and pitch. Experienced with fluid. [14] A dull, muffled sound may replace resonance in conditions like pneumonia or hemothorax. Hyper-resonance: Very loud, very low pitch, and longer in duration. Abnormal. [14] Hyper-resonance can result from asthma or emphysema
Vocal cord dysfunction (VCD) is a condition affecting the vocal cords. [1] It is characterized by abnormal closure of the vocal folds, which can result in significant difficulties and distress during breathing, particularly during inhalation. [1] Due to the similarity in symptoms, VCD attacks are often mistaken for asthma attacks or laryngospasms.
Spontaneous pneumothoraces are divided into two types: primary, which occurs in the absence of known lung disease, and secondary, which occurs in someone with underlying lung disease. [17] The cause of primary spontaneous pneumothorax is unknown, but established risk factors include being of the male sex, smoking , and a family history of ...
