Vesicular resonance
The resonance obtained by percussion of normal lungs.
-
Tympanitic resonance
The resonance obtained by percussion of a hollow structure, such as the stomach or colon, when it is moderately distended with air.
-
Tympanic resonance
A low-pitched, drum like sound heard on percussion over a large air-containing space.
-
Skodaic resonance
An increased percussion sound over the upper lung when there is a pleural effusion in the lower part.
-
Electron spin resonance
A technique used in medical imaging that identifies atoms by their electron spin characteristics.
-
Cracked-pot resonance
The peculiar clinking sound sometimes heard on chest percussion in cases of advanced tuberculosis when cavities are present. A distinct clinking noise that can sometimes be elicited by tapping over tuberculous cavities in the chest, known as vesicular resonance. This sound is in contrast to the noise produced over a healthy, air-filled lung.
-
Bell-metal resonance
The sound heard in pneumothorax on auscultation when a coin is held against the chest wall and struck by another coin.
-
Bandbox resonance
The pulmonary resonance heard during chest percussion in patients with emphysema.
-
Amphoric resonance
A sound similar to that produced by blowing across the mouth of an empty bottle. A noise reminiscent of the sound created when blowing across the opening of an empty bottle’s neck.
-
Viscous resistance
Non-elastic opposition of tissue to ventilation due to the energy required to displace the thorax and airways.
