Fremitus is a vibration transmitted through the body. [1] In common medical usage, it usually refers to assessment of the lungs by either the vibration intensity felt on the chest wall (tactile fremitus) and/or heard by a stethoscope on the chest wall with certain spoken words (vocal fremitus), although there are several other types.
Crepitus is often loud enough to be heard by the human ear, although a stethoscope may be needed to detect instances caused by respiratory diseases. In times of poor surgical practice, post-surgical complications involved anaerobic infection by Clostridium perfringens strains , which can cause gas gangrene in tissues , also giving rise to crepitus.
These cases result in immediate onset (usually) painless swelling of the face and neck; crepitus (crunching sound) typical of subcutaneous emphysema is often present and the subcutaneous air will be visible on X-ray. [24] One of the main causes of subcutaneous emphysema, along with pneumothorax, is an improperly functioning chest tube. [2]
There’s even a medical name for that crackling, clicking or popping sound your bones make: crepitus. Popping joints can happen involuntarily, and you can experience it in your knees, neck ...
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 ...
Percussion of the chest may be perceived as hyperresonant (like a booming drum), and vocal resonance and tactile fremitus can both be noticeably decreased. Importantly, the volume of the pneumothorax may not be well correlated with the intensity of the symptoms experienced by the victim, [ 15 ] and physical signs may not be apparent if the ...
Increased vibration of the chest when speaking, known as tactile fremitus, and increased volume of whispered speech during auscultation can also indicate the presence of fluid. [14] Several tests can identify the cause of CAP. Blood cultures can isolate bacteria or fungi in the bloodstream.
Based on the auditory and tactile perception, the notes heard can be categorized as: [3] Tympanitic, drum-like sounds heard over air filled structures during the abdominal examination. [4] Hyperresonant (pneumothorax), said to sound similar to percussion of puffed up cheeks. Normal resonance/ Resonant, the sound produced by percussing a normal ...
