Stopping Severe Bleeding

Stop the Bleeding

Why this matters

Blood carries oxygen to vital organs. Heavy blood loss leads to shock and death. Simple pressure, applied immediately and held steadily, saves lives while an ambulance is on the way.

Steps

Follow these in order when you need this skill.

Ensure scene safety and call for help
Make sure you are safe. Call emergency services or send someone to call. Ask bystanders for clean cloth, gauze, or a first-aid kit.
Apply direct pressure
Place a clean cloth, gauze pad, or your bare hand directly on the wound. Press firmly and continuously. Do not peek repeatedly — lifting the dressing restarts bleeding.
Add more material if blood soaks through
If blood comes through the dressing, do not remove it. Add more layers on top and keep pressing.
Press for a sustained period
Maintain firm pressure for at least 10 minutes without lifting. For severe limb bleeding, continue until professional help arrives.
Do not remove embedded objects
If something is stuck in the wound — glass, metal, knife — do not pull it out. Build padding around the object and press around it, not on it.
Know when to escalate
If direct pressure does not control life-threatening limb bleeding, a tourniquet may be needed if you are trained and have one. Lay the person down, keep them warm, and monitor until help arrives.

Common mistakes

Things that can make the situation worse

Lifting the dressing to check if bleeding stopped — this disrupts clotting.
Using a tourniquet as the first step for minor bleeding.
Removing embedded objects from wounds.
Delaying the call for help while searching for perfect supplies.

Practice

Practice applying firm pressure to a rolled towel on a table for a full 2 minutes without lifting. Notice how steady pressure feels different from quick, repeated taps.

Key takeaways

Direct pressure is the first and most important step.
Do not remove dressings that soak through — add layers on top.
Never pull out embedded objects.
Call emergency services for severe bleeding immediately.

Comprehension questions(2 — optional, no score)

Question 1

Blood soaks through your cloth bandage. What do you do?

Remove the bandage and start over
Add more layers on top and keep pressing
Stop pressing and wait
Elevate the limb without pressure

See explanation

Answer: Add more layers on top and keep pressing. Removing the dressing disrupts clot formation. Add layers and maintain continuous pressure.

Question 2

A piece of glass is stuck in a wound and bleeding heavily. What do you do?

Pull the glass out quickly
Leave it in place and pad around it
Wash the wound with soap first
Apply a tourniquet above the glass

See explanation

Answer: Leave it in place and pad around it. Embedded objects may be limiting bleeding. Stabilize in place and build padding around the object.
