How to guide

What is chest injury?

Chest injuries range from minor bruising and simple rib fractures to serious conditions such as flail chest, pneumothorax and haemothorax, which can severely impair breathing and circulation. Typical symptoms include chest pain, especially on breathing or movement, tenderness, bruising, shortness of breath and, in more serious cases, paradoxical chest wall movement or signs of shock.

First aid priorities are to support breathing, minimise pain and movement, recognise signs of life‑threatening chest injury and call 999 early; advanced interventions such as needle decompression are outside basic first aid scope and reserved for trained clinicians under governance.

Blunt chest trauma and rib fractures are common after falls, assaults and road traffic collisions; multiple rib fractures and flail chest significantly increase the risk of breathing problems, pneumonia and mortality.

Who needs this skill?

Any setting where falls from height, crush injuries, assaults or vehicle incidents may occur needs staff alert to chest injury red flags.

Health & Social Care

In health and social care, chest injuries often affect older adults after falls and people with underlying lung disease; clinicians must balance pain control and mobilisation with respiratory support and VTE prevention. First responders should focus on airway, breathing, circulation and early escalation to hospital trauma teams.

Licensed venues & nightlife

In nightlife and licensed venues, assaults and crowd crush incidents can cause chest trauma; staff must recognise that someone complaining of chest pain or struggling to breathe after being struck or crushed needs urgent assessment, not merely ejection or observation.

Schools

Serious chest trauma is rarer in schools but can occur in sports, road traffic incidents near the site or assaults; senior staff and first aid leads should understand chest red flags for staff and older students.

Workplaces

In workplaces, chest injuries may result from falls, impacts from tools or vehicles, or crushing by loads; first aiders should conduct a primary survey, support the chest in a comfortable position and call 999 for significant pain, breathing difficulty or suspected serious injury.

How to manage chest injury

These steps show how to support someone with chest pain after a blow, make breathing easier and recognise when 999 is required.

1

Ensure airway and breathing are supported

Assess airway and breathing, looking for rate, depth, symmetry and signs of distress such as use of accessory muscles, cyanosis or inability to speak in full sentences.

If breathing is compromised or they become unresponsive, follow BLS/ALS algorithms, including CPR where indicated.

2

Position for ease of breathing

If conscious and able, help the casualty to sit upright or in a position of comfort, often leaning slightly forward or towards the injured side, which can reduce pain and improve ventilation.

Avoid lying them flat if this worsens breathing; if they must lie down, support the head and chest slightly raised.

3

Support the injured area

Allow the casualty to support the painful area with their hand, pillow or folded clothing, or apply gentle strapping over loose bulky padding if within your training, to reduce movement of the chest wall.

Do not strap the chest so tightly that it restricts breathing, and do not apply circumferential bandages around the entire chest.

4

Recognise and act on red flags

Red flags include severe or worsening breathlessness, very fast or very slow breathing, obvious deformity or instability of the chest wall, paradoxical movement suggesting flail chest, signs of shock or tracheal deviation.

Call 999 immediately if any red flags are present, stating that you suspect a serious chest injury, and follow dispatcher advice.

5

Monitor, document and hand over

Continue to monitor breathing, pulse, level of consciousness and pain, and record observations and timings to hand over to ambulance crews.

Provide a clear history of the mechanism of injury, initial findings and changes in condition, as this helps trauma teams prioritise investigations and treatment.

B

Can a single broken rib be managed without hospital?

Some simple rib injuries in otherwise healthy people can be managed at home with pain relief and breathing exercises, but clinical assessment is often needed to rule out complications such as pneumothorax. First aiders should not make this decision; if in doubt, advise or arrange medical review.

B

What is a flail chest and why is it serious?

Flail chest occurs when a segment of the rib cage breaks in multiple places and moves paradoxically compared to the rest of the chest wall, severely impairing breathing and often indicating high-energy trauma. It is a medical emergency requiring hospital care.

B

Should first aiders ever apply bulky dressings to the chest?

Bulky dressings or padding can be used to support painful areas and reduce movement, but they must not encircle the chest or restrict breathing. Open chest wounds require specific management according to advanced training and current guidance.

B

How is chest injury risk different in older adults?

Older adults have more fragile bones and less respiratory reserve, so even apparently minor chest trauma can lead to serious complications like pneumonia and respiratory failure. Thresholds for hospital assessment should therefore be lower.

B

How can workplaces and venues reduce chest injury risks?

Controls include falls prevention, safe systems for manual handling and transport, violence reduction measures and crowd management plans, along with regular drills and post-incident reviews to improve practice.
