Chest trauma
A streamlined, differential-led presentation for rapid clinical review.
Twenty-second review
- Chest trauma can impair ventilation or circulation through rib injury, pulmonary contusion, pneumothorax, hemothorax, tamponade, or great-vessel injury.
- Severe dyspnea, asymmetric or absent sounds, shock, flail segment, penetrating wound, or distended neck veins requires rapid intervention and transport.
- Keep acs or pulmonary disease in the differential; overlapping or concurrent illness remains possible.
- For chest trauma, trends and combinations of findings are more informative than one isolated vital sign.

The repeated material is grouped inside each possibility. Open only the condition you need.
Tension pneumothoraxTime-sensitive high-risk possibility
HPI
Clarify mechanism and force; respiratory distress; chest-wall findings.
Signs & symptoms
Respiratory or circulatory compromise with mechanism-specific findings.
Focused exam
Expose only as needed, inspect and palpate systematically, and document distal circulation, sensation, and movement; Reassess pain, swelling, perfusion, and neurologic status after movement or intervention.
Brief pathophysiology
Tension pneumothorax may cause chest trauma through a time-sensitive process capable of rapid physiological deterioration.
What the trend may show
Thoracic injury can evolve from respiratory compromise to obstructive or hemorrhagic shock. Integrate symmetry, air entry, work of breathing, and perfusion with serial observations.
Respiratory rate (breaths/min)
Often risesTachypnea commonly reflects pain, hypoxemia, or impaired mechanics.
