fremitus

Hepatic fremitus is a vibration felt over the patient's liver.

Subjective fremitus is a vibration felt by the patient on humming with the mouth closed.

Fremitus is a palpable vibration on the body.

In common medical usage, it usually refers to (tactile) vocal fremitus, although there are several other types.

Tussive fremitus is a vibration felt on the chest when the patient coughs.

Tooth movement that occurs during occlusal loading is sometimes termed fremitus.

Fingers placed in the labial vestibule against the alveolar bone can detect fremitus.

Lastly, vocal fremitus is performed.

Periodontal fremitus occurs in either of the alveolar bones when an individual sustains trauma from occlusion.

Pericardial fremitus is a vibration felt on the chest wall due to the friction of the surfaces of the pericardium over each other.

Hydatid fremitus is a vibratory sensation felt on palpating a hydatid cyst.

Tactile fremitus, with the patient asked to say boy-O-boy or ninety-nine, and the physician using the ulnar aspect of their hand to feel changes in sound conduction.

Increased vibration of the chest when speaking (tactile fremitus) and increased volume of whispered speech during auscultation of the chest can also reveal consolidation.

Pleural fremitus is a palpable vibration of the wall of the thorax caused by friction between the parietal and visceral pleura of the lungs.

It has recently been suggested that the artifacts caused by eliciting tactile fremitus during breast ultrasonography can be used to differentiate between benign and malignant tumors.

Percussion of the chest may be perceived as hyperresonant (like a booming drum), and vocal resonance and tactile fremitus can both be noticeably decreased.

Rhonchal fremitus, also known as bronchial fremitus, is a palpable vibration produced during breathing caused by partial airway obstruction.

Other terminology for sounds that may be auscultated in the thorax include crackles, wheezes, pleural rubs, pulmonary murmurs, egophony, whispering pectoriloquy, vocal fremitus and rales.

Tactile fremitus is normally more intense in the right second intercostal space, as well as in the interscapular region, as these areas are closest to the bronchial bifurcation.

Patients may present with the signs of pleural effusion: dullness on percussion, diminished or absent breath sounds and vocal fremitus, and egophony at the level of the pleural liquid.

Conversely, the reason for decreased fremitus in a pleural effusion or pneumothorax (or any pathology separating the lung tissue itself from the body wall) is that this increased space diminishes or prevents entirely sound transmission.

The reason for increased fremitus in a consolidated lung is the fact that the sound waves are transmitted with less decay in a solid or fluid medium (the consolidation) than in a gaseous medium (aerated lung).

Tactile fremitus is pathologically increased over areas of consolidation and decreased or absent over areas of pleural effusion or pneumothorax (when there is air outside the lung in the chest cavity, preventing lung expansion).

He also recognized that information with regard to the contents of cavities in the lungs and conditions of lung tissue might be obtained by placing the hand on the chest and noting the vibration, or fremitus, produced by the voice and breath.

Tactile Fremitus, known by many other names including pectoral fremitus, tactile vocal fremitus, or just vocal fremitus, is a vibration felt on the patient's chest during low frequency vocalization.
