When Seconds Matter: What the Public Should Know About Severe Bleeding

Severe bleeding can happen almost anywhere.

A serious injury may result from a vehicle crash, workplace accident, broken glass, power tools, recreational activities, falls, or other unexpected incidents. In a major emergency, multiple people may also be injured at the same time.

Professional emergency responders should be activated immediately when an injury is serious, but severe bleeding can become life-threatening before an ambulance arrives.

Knowing how to recognize dangerous bleeding and take appropriate action can make an important difference during those first critical minutes.

Recognizing Life-Threatening Bleeding

Not every cut or wound represents a life-threatening emergency.

Severe bleeding requires immediate attention when blood loss is significant or difficult to control.

Warning signs can include:

1. Blood flowing continuously or rapidly from a wound

2. Blood pooling on the ground or soaking through clothing

3. Bleeding that does not stop with firm direct pressure

4. Partial or complete loss of a limb

5. A seriously injured person becoming pale, confused, weak, or unresponsive

6. Other signs that suggest substantial blood loss

When in doubt about the severity of an injury, activate emergency medical services and follow the instructions provided by the emergency dispatcher.

Make Sure the Scene Is Safe

Before helping an injured person, look for hazards.

Traffic, fire, broken glass, unstable structures, electrical hazards, violence, machinery, or other dangers may still be present.

Do not create another victim by entering an unsafe environment.

Call 911 as soon as possible or direct another person to make the call. If other people are nearby, assign tasks clearly.

Instead of shouting, "Someone call 911," identify a specific person and ask that person to call.

Apply Firm Direct Pressure

For severe external bleeding, direct pressure is an important first response.

Expose the injury if necessary so you can identify where the blood is coming from. Place gauze, a trauma dressing, or other appropriate material directly over the wound and apply firm, continuous pressure.

Maintain pressure rather than repeatedly removing the dressing to inspect the wound.

If blood comes through the material, continue following appropriate bleeding-control procedures rather than repeatedly interrupting pressure.

Disposable medical gloves or another appropriate barrier should be used when available.

Understand the Role of Tourniquets

For life-threatening bleeding from an arm or leg, a commercial tourniquet may be necessary.

Tourniquets are designed to control severe extremity bleeding by stopping blood flow to the injured area.

Proper training is strongly recommended. A tourniquet must be positioned and tightened correctly to be effective.

Once an effective tourniquet has been applied for life-threatening bleeding, it generally should not be loosened or removed by an untrained bystander. Emergency medical professionals should manage subsequent care.

Improvised devices may not perform like commercially manufactured tourniquets and can be difficult to use effectively.

Wound Packing Can Be Another Important Skill

Some severe wounds occur in locations where a tourniquet cannot be used.

Depending on the injury, trained responders may use wound packing with appropriate gauze followed by firm pressure to control bleeding.

Like tourniquet use, wound packing is a practical skill best learned through hands-on instruction rather than for the first time during an actual emergency.

Watch for Signs of Shock

Severe blood loss can cause shock, a life-threatening condition in which the body's organs are not receiving adequate blood flow.

An injured person may become:

1. Pale or clammy

2. Weak or dizzy

3. Confused or unusually anxious

4. Rapidly breathing

5. Increasingly less responsive

Continue monitoring the person's condition while waiting for emergency medical services.

Do not give food or drink to a seriously injured person unless directed by qualified medical personnel.

Bleeding-Control Equipment Should Be Accessible

First aid kits are common in workplaces, schools, vehicles, houses of worship, and public facilities, but many were designed primarily for minor injuries.

Organizations should consider whether their emergency equipment matches the hazards they may realistically encounter.

Bleeding-control kits may contain items such as commercial tourniquets, gauze, trauma dressings, gloves, and other supplies.

Equipment is most useful when people know where it is located and have been trained to use it.

Preparedness Takeaways

1. Recognize severe, uncontrolled bleeding as a medical emergency.

2. Make sure the scene is safe before approaching an injured person.

3. Call 911 as quickly as possible.

4. Apply firm, continuous direct pressure to severe external bleeding.

5. Use protective gloves or another barrier when available.

6. Commercial tourniquets can control life-threatening bleeding from an arm or leg.

7. Hands-on training improves the ability to use bleeding-control equipment correctly.

8. Watch seriously injured people for changes in responsiveness and signs of shock.

9. Know where first aid and bleeding-control equipment is located.

10. Never delay activating EMS while attempting to manage a serious injury alone.

Turning Bystanders Into Immediate Responders

A severe bleeding emergency can occur long before trained responders reach the patient's side. That makes public education an important part of community preparedness.

CPR, AED use, first aid, and bleeding-control skills give ordinary people practical ways to help during the critical period between an emergency occurring and professional responders arriving.

BVAC Rescue Response Training Center provides first aid and bleeding-control education, including hands-on emergency-response training designed to build practical skills and community readiness.

You do not need to be a paramedic to recognize that someone is in serious trouble. Knowing how to call for help, control severe bleeding, and use available emergency equipment can help turn a bystander into an immediate responder when seconds matter.
