|
|
|
Suggests the presence of fluid or air outside of the lung

Explanation:
Detailed explanation-1: -Changes in the intensity of tactile fremitus can be used to detect areas of unusual lung tissue density. The assessment of tactile fremitus is based on the principle that sound vibrations are conducted better through solid or fluid mediums, as opposed to air, which causes a decay in sound transmission.
Detailed explanation-2: -Overview. Tactile fremitus is an assessment of the low-frequency vibration of a patient’s chest, which is used as an indirect measure of the amount of air and density of tissue present within the lungs.
Detailed explanation-3: -Palpation is the tactile examination of the chest from which can be elicited tenderness, asymmetry, diaphragmatic excursion, crepitus, and vocal fremitus.
