==Background==
*Direct injury to lung resulting in hemorrhage and edema in absence of lung laceration
*Flail chest almost always associated with contusion
 
==Clinical Features==
*[[Dyspnea]]
*Tachypnea
*[[Chest pain]]
*Coarse breath sounds
*[[Hypoxia]]
*Widened A-a gradient


==Differential Diagnosis==
{{Thoracic trauma DDX}}

{{Pulmonary edema types}}

==Evaluation==
*Areas of lung opacification on chest imaging within 6hr of blunt trauma is diagnostic
*[[CXR]]
**Patchy irregular infiltrates
*CT
**Ground-glass opacities in mild-moderate contusions, widespread consolidation if severe
**May pick up 70% of contusions not seen on CXR
**Contusion >20% of lung volume associated with 80% risk of developing ARDS

==Management==
*Ensure adequate ventilation
**[[Analgesia]]
**Ventilatory Assistance
***Patients with >25% of lung involvement frequently require ventilatory assistance
***[[NIPPV|NIV]] may be tried
***[[Intubate]] if NIV fails
****Low tidal volume, high PEEP
*Avoid unnecessary fluid administration
