Q

Tactile Fremitus

A

palpable vibration

Sounds generated from the larynx are transmitted through patent bronchi and through the lung parenchyma to the chest wall, where you feel them as vibrations

test for vibrations bilaterally using the phrase “ninety nine” (except between the scapulae, where the bronchial bifurcation is closer on the right side, which makes the vibrations stronger)

Q

Decreased fremitus

A

occurs when anything obstructs transmission of vibrations (e.g., obstructed bronchus, pleural effusion or thickening, pneumothorax, or emphysema). Any barrier that comes between the sound and your palpating hand will decrease fremitus.

Q

Increased fremitus

A

occurs with compression or consolidation of lung tissue (e.g., lobar pneumonia). This is present only when the bronchus is patent and when the consolidation extends to the lung surface. Note that only gross changes increase fremitus. Small areas of early pneumonia do not significantly affect fremitus

What is egophony and why is it used?
The patient says "ee" during auscultation.... Normal lung tissue does not transmit sound well and produces a characteristic muffled "aa" sound. Consolidated lung tissue, on the other hand, produces a clear and distinct "ee" sound because of its higher density. -used to determine resonance

63
what are the 4 major functions of the respiratory system?
1. supplying the o2 to the body for energy production 2. removing co2 as a waste product of energy reactions 3. maintaining homeostasis (acid-base balance) of arterial blood. 4. maintaing heat exchange (less important in humans).

Symmetric chest expansion
Slide your hand medially to pinch up a small fold of skin between your thumbs. Ask the person to take a deep breath. Your hands serve as mechanical amplifiers. As the person inhales, your thumbs should move apart symmetrically. Unequal chest expansion occurs with marked atelectasis, lobar pneumonia, pleural effusion, with thoracic trauma, such as fractured ribs; or with pneumothorax.
78
Fremitus, the vibrations should feel the same in the corresponding area on each side with the exception of?
Just between the scapula, fremitus may feel stronger on the right side than on the left side because the right side is close to the bronchial bifurcation.

Scattered dullness

83
Vesicular
