chest trauma

blunt or penatrating injuries OR a combination of blunt and penetrating injuries to chest wall and lung parenchyma

associated w/ deceleration, acceleration, or compression injuries (nothing went through the chest wall)

deceleration =

acceleration =

low- speed penetrating trauma

high-speed penetrating trauma

abnormal accumulation of air in the subcutaneous or soft tissues seen on chest xray

affted area of the chest wall moves inward w/ inspiration or outward w/ expiration is termed

worsened w/ positive pressure ventilation. persistent leakage of air into the pleural space despite proper chest tube placement and suction.

rare. treatment includes rapid repair of the underlying injury.

compression of the heart due to a build-up of blood in the pericardium.

treatment includes surgery/ emergent needle thoracotomy

defined as an abnormal dilatation of the aorta

blood makes its way btwn the laters of a blood vessel wall, seperating them.

treatment is surgical repair

simple rib fractures usually involves ribs

simple rib fractures may result in (4)

treatment of simple rib fracture includes

two or more fractures on each affected rib that result in a free floating portion of the rib cage

flail chest causes

flail chest trauma usually includes pulm contusion which results in the alveoli and may result in (3)

treatment of flail chest includes

associated w/ penetrating chest trauma, but also seen with severe blunt trauma from explosive blasts

associated w/ penetrating trauma, air enters the pleural space during inspiration, but cannot exit the plueral space bc the parietal pleura acts as a one way valve

in closed or tension pneumothorax the mediastinum shifts _____ from the affected area

when mediastinum shifts away from the affected area, it causes (3)

presence of blood in the pleural space. can be associated with blunt or penetrating trauma is termed

presence of air and blood in the pleural space is termed

bronchopleural fistula worsens with what type of ventilation

flail chest treatment

general trauma treatment (7)

associated w/ blunt chest trauma when lung impacts against the chest wall. alveolar microvascular damage allows blood to enter alveoli is termed as

results from a penetrating injury. result in a sliding motion and the tearing of the lung parenchyma.

often seen in association w/ pulm contusion.

usually resolves spontaneously
