Pneumothorax
Air getting into the pleural space

An open Pneumothorax is when there’s a wound starting from
the outside of the body, exposing the pleural space
A closed Pneumothorax example is
a person with COPD has a spontaneous tear
Pneumothorax: percussion would show
hyperresonance
In a closed Pneumothorax there is no where for the pressure to go so
it builds up an pushes the trachea in the other direction
Tension Pneumothorax involves
the lung collapsing
Tension Pneumothorax: When the pt breathes in, air gets in the the pleural space but
doesn’t get back out when they exhale
Tension Pneumothorax: pressure builds up in the pleural space and compresses
blood vessels, decreasing blood flow and therefore decreases CO.
Pneumothorax that’s an emergency
Tension
