Palpation Def.
|
The act of touching the chest wall in an effort to evaluate lung structure and function
|
|
|
Palpation is a technique that evaluates...
|
Position of the trachea
Lung expansion/chest wall movement Vocal Fremitus Skin & Subcutaneous tissues - chest |
|
|
Purpose of Palpation
|
To confirm or rule out suspected Pulm. problems suggested by
-Pt. History -Initial physical inspection |
|
|
Pleural Effusion
|
Accumulation of fluid in pleural space
Causes a tracheal shift away from affected side |
|
|
Atelectasis
|
The collapse of a portion of the lung
Decreses the size of the affected lung Cause a trach shift toward affected side |
|
|
Simple Pneumothorax
|
Presence of air in pleural space
Pleural surfaces seperate The collapse of a portion of the lung Decreases the size of the affected lung Causes a trach shift toward affected side |
|
|
Tension Pneumothorax
|
Air enters pleural space but cannot exit
Intrapleural pressure becomes positive, greater then atm (tension) Life-threatening Mediastinal structures shifted away from affected area |
|
|
Consolidation
|
Air containing areas of the lung become filled with solids or liquids
-tumor -mucus No change in size of lung No shift in trach position |
|
|
Palpation + visual inspection=
|
Accurate assessment of chest wall movement
|
|
|
Chest wall movement reflects...
|
Lung expansion
|
|
|
Normal Symetrical Movement
|
Each Thumb moves an equal distance but in opposite direction from the midline
|
|
|
Asymetrical Movements
|
Each thumb moves an unequal distance in opposite direction from midline
Movement that is decreased unilaterally but mostly normal on opposite side |
|
|
Causes of Asymetrical Movement
|
Pleural Effusion
Atelectasis Peumothorax Consolidation *Movement decreased on affected side |
|
|
Vocal Fremitus
|
Vibrations created by the vocal cords during speech that are transmitted to the chest wall via that trach. tree
|
|
|
Tactile Fremitus
|
When vibrations are felt on the chest wall
|
|
|
Increased Fremitus
|
Increased by any condition that tends to increase the density of the lung
Pneumonia Lung Tumor Atelectasis |
|
|
Decreased Fremitus
|
Decreased by any condition that tends to inhibit transmission of vibrations
Mucus plugging of a bronchus Foreign body obstructing a bronchus Pneumothorax Pleural Effusion |
|
|
Skin and Subcutaneous Tissues
|
Temp of skin
Presence of subcutaneous air-chest area -Subcutaneous emphysema -free air that collects under the skin -migrated there along tissue planes -from an air leak in the lung tissue |
