RESPIRATORY - disruptions in the pleural lining Flashcards
EXAM 2 content
what does disruptions of the pleural lining lead to?
changes the ability of the lungs to inflate, they basically deflate
how can pleural lining disruption be categorized?
- pleural effusion
- hemothorax
- pneumothorax
- tension pneumothorax
what is the pathophysiology of pleural lining disruption?
something causes disruption of visceral or parietal pleura –> disruption of pleural space
–> change in pressure
–> lungs to collapse
–> restricts ability to expand, ventilate, perfuse & diffuse gasses
–> hypoxia
what are the classifications of pleural lining disruptions?
- open or closed
- primary, secondary, or traumatic
- stable or unstable
what are the different types of disruptions?
- pneumothorax: air enters pleural space
- hemothorax: blood enters pleural space
- pleural effusion: fluid enters pleural space
- tension pneumothorax: air enters pleural space but CANT LEAVE –> shifting & compressing organs
or COMBO of all the above
what are the risk factors of disruption?
- traumatic injury
- lung (visceral pleura) damage from smoking
- genetic conditions: marfan syndrome
- barotrauma from mech ventilation: trauma from pressure
- chronic lung disease
- tall cisgender maes: spontaneous pneumothorax
what are the pleural lining disruption manifestations?
- neuro: confusion & altered LOC
- CV: angina, hypotension, tachycardia, muffled heart sounds 9esp with tension pneumothorax)!
- resp: dyspnea, tachypnea, diminished or absent breath sounds! tracheal deviation for tension pneumothorax!
what diagnostics would we use for pleural lining distruption?
- chest x -ray: BLACK = FREE SPACE = COLLAPSED LUNG
- CT
- thoracentesis
how would we treat pleural lining disruptions?
- focused on removing fluid or air from space
- pharmacological management is focused on secondary issues
what are the complications of pleural lining disruptions?
hypoxia –> respiratory collapse –> cardiovascular collapse –> cardiac arrest –> death
some can have small collapses and will resolve on its own
