can access deeper structure w/o puncturing the lungs and other organs
|
|
|
Area of cardiac dullness
|
absence of pleural between the lungs. upon auscultation, a dull sound will be heard
|
|
|
Left & Right Costodiaphragmatic I & II
|
pleural spaces where lungs are not present
|
|
|
Performing Pericardiocenthesis
|
1. 5th & 6th intercostal spaces near the sternum
2. infrasternal angle: can puncture thoracic artery or branches |
|
|
Pleuritis
|
parietal & visceral pleura slide past one another during inspiration
makes a sound irritation of pleura |
|
|
Left Lung
lobes fissures tongue |
2 lobes: superior & inferior
1 fissure: oblique lingula of the lung - tongue |
|
|
Right Lung
lobes fissures borders surfaces (DMC) |
3 Lobes: superior, middle & inferior
2 fissures: horizontal & oblique Anterior : sharp Posterior Inferior Surfaces: Diaphragmatic, Mediasitinal & Costal |
|
|

|
Left lung is in contact with
|
Left Subclavian artery
aortic arch cardiac impression descending aorta esophagus |
|
|
Right lung is in contact with
|
Cardiac Impression
Azygous SVC / IVC Subclavian artery Esophagus |
|
|
Pulmonary Collapse
causes end result |
1. stab wound or GSW to thoracic wall
2. damage to the visceral pleural 2' Atelectasis b/c intrathoracic pressure becomes positive from negative mediastina shifts toward affected side |
|
|
Tenison Pneumothorax
|
air seeps into the pleural cavity from the lungs. As air moves in, the pressure gets more positive.
Mediastina will shift towards affected side |
|
|
1' Atelectasis
|
lungs are unable to inflate during first inspiration
|
|
|

|
|
|
