Chest trauma

A streamlined, differential-led presentation for rapid clinical review.

Clinical snapshot

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.

Serious4 conditions
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.

Vital-sign pattern

What the trend may show

Possible pattern

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 rises

Tachypnea commonly reflects pain, hypoxemia, or impaired mechanics.

Oxygen saturation (SpO₂)

May fall

Desaturation supports significant gas-exchange impairment but may lag.

Heart rate (bpm)

Often rises

Tachycardia may accompany distress, hypoxia, or shock.

Blood pressure (mmHg)

May fall late

Hypotension raises concern for tension physiology or significant hemorrhage.

Brief pathophysiology

Tamponade may cause chest trauma through a time-sensitive process capable of rapid physiological deterioration.

Vital-sign pattern

What the trend may show

Possible pattern

Shock can be present before profound hypotension. Trend perfusion, mental status, pressure, and pulse characteristics; the direction varies with cause and treatment.

Blood pressure (mmHg)

May fall

Relative change from baseline may be important before absolute hypotension appears.

MAP (mmHg)

May fall

A falling MAP supports impaired perfusion but is not the only endpoint.

Heart rate (bpm)

Often rises

Tachycardia is common; neurogenic, toxic, paced, or medication effects can alter the response.

Pulse pressure (mmHg)

May narrow

Narrow pulse pressure can reflect reduced stroke volume, although distributive states may differ.

Front-load in the triage report

  • Tamponade: Respiratory or circulatory compromise with mechanism-specific findings.
  • Chest-wall findings?
  • Breath sounds and SpO₂?
Aortic injuryTime-sensitive high-risk possibility

HPI

Signs & symptoms

Respiratory or circulatory compromise with mechanism-specific findings.

Focused exam

Reassess pain, swelling, perfusion, and neurologic status after movement or intervention; Inspect symmetry and wounds, palpate gently for tenderness and instability, auscultate bilaterally, and assess perfusion and neck veins.

Brief pathophysiology

Aortic injury may cause chest trauma through a time-sensitive process capable of rapid physiological deterioration.

Vital-sign pattern

What the trend may show

Possible pattern

Isolated injury may have normal observations. Serial heart rate, pressure, respiratory status, and oxygenation help identify occult hemorrhage or thoracic injury.

Heart rate (bpm)

May rise

Pain, distress, and hemorrhage can increase rate; medications can blunt it.

Blood pressure (mmHg)

May fall late

A normal pressure does not exclude compensated hemorrhage.

Respiratory rate (breaths/min)

Trend rate / effort

Tachypnea may reflect pain, thoracic injury, shock, or acidosis.

Oxygen saturation (SpO₂)

Usually preserved

Low saturation suggests thoracic injury, hypoventilation, or concurrent disease.
