Chest Injuries
• Blunt trauma
– Can fracture ribs, sternum, and costal (rib)
cartilages
• Compression
– Occurs when severe blunt trauma causes the
chest to rapidly compress

Open Chest Injuries
• Difficult to tell what is injured from
entrance wound
• Assume all wounds are life-threatening
• Open wounds allow air into chest
– Sets imbalance in pressure
– Causes lung to collapse
![Page 15: Introduction to Emergency Medical Care 1 · 2015-08-20 · Title: Chapter 24 Poisoning and Overdose Author: Ted Created Date: 12/5/2011 5:04:39 PM](https://reader031.fdocuments.in/reader031/viewer/2022020416/5c9e1a4988c993c6368c115c/html5/thumbnails/15.jpg)

Limmer • O’Keefe • Dickinson
Think About It
• Does the patient’s chest injury need to be
treated during the primary assessment?
• Does the open chest injury require an
occlusive dressing?
• Does the patient’s injury necessitate
immediate transport to a trauma center?

cannot fill

abdominal cavity causing irritation.

Remember
• Blunt trauma, penetrating trauma, and
compression are mechanisms that can
injure the chest and abdomen.
• Open or closed pertains to the integrity of
the chest or abdominal wall after injury.
• Seal open chest wounds to prevent air
from entering the chest cavity.
