Gunshot Wound to the Chest: Emergency Awareness and First Aid Priorities

A gunshot wound to the chest is a life-threatening emergency due to the number of vital organs located within the chest cavity, including the heart, lungs, and major blood vessels. Injuries to this area can deteriorate rapidly and require immediate emergency medical care.

Gunshot wounds are considered penetrating injuries, meaning the projectile enters the body and damages tissue along its path. The severity of injury depends on multiple factors, including the type of firearm used, distance from the weapon, trajectory of the projectile, and structures involved.

Why Chest Gunshot Wounds Are Especially Dangerous

The chest protects organs essential for breathing and circulation. A penetrating injury can result in:

• Damage to one or both lungs
• Internal bleeding into the chest cavity
• Collapsed lung (pneumothorax)
• Injury to the heart or major blood vessels
• Rib fractures that worsen internal trauma

In some cases, a bullet may both enter and exit the chest, increasing tissue damage and risk of complications.

Recognizing Serious Chest Injuries

Signs and symptoms of a gunshot wound to the chest may include:

• Difficulty breathing or rapid, shallow breathing
• Chest pain that worsens with movement or breathing
• Visible open wound to the chest
• Air movement or bubbling at the wound site
• Bluish discoloration of lips or skin (cyanosis)
• Anxiety, confusion, or decreased alertness
• Signs of shock, such as pale or clammy skin

An open chest wound can allow air to enter the chest cavity, increasing pressure around the lungs and interfering with breathing.

First Aid Awareness and Immediate Response

A gunshot wound to the chest requires emergency medical services immediately. From a first aid awareness perspective, priorities focus on:

• Calling emergency services without delay
• Assessing airway, breathing, and circulation (ABCs)
• Keeping the injured person as still and calm as possible
• Monitoring breathing, level of consciousness, and skin colour

Any open chest wound should be treated as a medical emergency due to the risk of oxygen deprivation and rapid deterioration.

Medical Care and Hospital Treatment

Definitive treatment for a chest gunshot wound is performed in a hospital setting and may include:

• Advanced airway and breathing support
• Chest tube placement to restore lung function
• Surgical repair of damaged structures
• Management of internal bleeding and infection risk

Early emergency response greatly improves outcomes.

Why First Aid Training Matters

Although first aid providers do not treat gunshot wounds definitively, first aid training plays a critical role in recognizing life-threatening injuries, activating emergency response systems quickly, and supporting the injured person until professional care arrives.

First aid and CPR training is an essential part of emergency preparedness in workplaces, public spaces, and communities across Canada.
