5 pulmonary injuries
Simple pneumothorax
Open pneumothorax
Tension pneumothorax
Hemothorax
Pulmonary contusion
Simple pneumothorax + definition
Mechanism is paper bag syndrome
Lung tissue is disrupted and air leaks into the pleural space
Definition of open pneumothorax
Free passage of air between atmosphere and pleural space
Air replaces lung tissue is
S/S for open pneumothorax

Creates a one-way pressure valve within the thorax
S/S for tension pneumothorax
