Egophony: While listening to the chest with a stethoscope, ask the patient to say the vowel “e”. Over normal lung tissues, the same “e” (as in “beet”) will be heard. If the lung tissue is consolidated, the “e” sound will change to a nasal “a” (as in “say”).
How would you describe 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.
What is a positive egophony?
Positive: Egophony is heard indicating some consolidation of lung tissue. Negative: No egophony is heard indicating normal lung tissue is present. False-positive: Occurs in the presence of fibrotic lung parenchyma.
When the patient says 99 the sound is clear and loud?
The term used to describe the voice sounds heard over consolidated lung is bronchophony (also called vocal resonance). It can be determined through the stethoscope when the patient says “99”, usually just audible but becoming louder when the lung is consolidated.
What does positive Egophony sound like?
Egophony is one type of a voice sound. The word “egophony” is derived from the Greek word “ego” which means “goat.” During auscultation, the patient is asked to say “Eee.” The “Eee” will be transformed into an “A” with the voice having a nasal or bleating quality (like the bleating of a goat).
What does Bronchophony test for?
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….

What is a positive Bronchophony test?
Bronchophony. This term represents a test to perform on the patient which may indicate that there is consolidation of the lung. Consolidation refers to increased density of the lung tissue, due to it being filled with fluid and/or blood or mucus.
What is the significance of testing for egophony?
Voiced sounds, such as egophony, can provide important information about the presence of a lung abnormality and its location. The basic idea is that normal lungs (filled with air), do not readily transmit sounds, while consolidated lung tissue more readily transmits sounds.
What does whispered Pectoriloquy indicate?
Whispered pectoriloquy is a clinical test typically performed during a medical physical examination to evaluate for the presence of lung consolidation, causes of which include cancer (solid mass) and pneumonia (fluid mass). …
What does egophony mean in medical terms?
Definition of Egophony. Voiced sounds, such as egophony, can provide important information about the presence of a lung abnormality and its location. The basic idea is that normal lungs (filled with air), do not readily transmit sounds, while consolidated lung tissue more readily transmits sounds.
How do you use egophony during an exam?
To use egophony during an exam, ask the patient to say ‘e’ as you auscultate over the chest wall. Over normal lung areas, you will here the same ‘e’ tones. Over consolidated tissue, the ‘e’ sound changes to a nasal quality ‘a’ (aaaaay), like a goat’s bleating.
What causes egophony in the lungs?
Accumulation of fluid or fibrosis in lung tissue enhances the transmission of high-frequency sounds while filtering out lower-frequency sounds leading to the high-pitched nasal/bleating sound characteristic of egophony To assess for the presence of: Instruct the patient to say the word “bee” every time you touch them with your stethoscope
How do you use egophony in a chest xray?
To use egophony during an exam, ask the patient to say ‘e’ as you auscultate over the chest wall. Over normal lung areas, you will here the same ‘e’ tones. Over consolidated tissue, the ‘e’ sound changes to a nasal quality ‘a’ (aaaaay), like a goat’s bleating. The sound will often become louder over consolidated tissue.
