Trauma Care and Bleeding Control — Stop the Bleed Before Emergency Services Arrive

Preparation

Introduction

Uncontrolled bleeding is the #1 cause of preventable death in trauma situations. A person can bleed to death from a major arterial wound in as little as 3-5 minutes. Emergency medical services average 7-10 minute response times in urban areas—longer in rural areas, and potentially much longer during crises.

This guide covers life-saving bleeding control: tourniquet application, wound packing, pressure dressings, and the equipment you need. These skills arent just for survival scenarios—they save lives in car accidents, workplace injuries, and everyday emergencies.

This is not a substitute for hands-on training. Find a Stop the Bleed course (free, nationwide) and practice. But understanding the principles now could save a life before you get that training.

Understanding Hemorrhage

Why Bleeding Kills

Blood Volume:

  • Average adult: 5 liters (1.3 gallons) of blood
  • Losing 1 liter (20%): Increased heart rate, anxiety
  • Losing 2 liters (40%): Shock, confusion, unconsciousness
  • Losing 2.5+ liters (50%): Usually fatal without immediate intervention

Time Matters:

  • Major arterial bleed: Death in 3-5 minutes
  • Major venous bleed: Death in 5-15 minutes
  • Moderate bleed: Shock in 30-60 minutes, death in hours

The Golden Hour:

  • Trauma victims have best survival rates when definitive care is received within 60 minutes
  • Bleeding must be controlled BEFORE transport
  • You are the first responder in most scenarios

Types of Bleeding

Arterial Bleeding:

  • Appearance: Bright red blood
  • Pattern: Spurts/pulses with heartbeat
  • Severity: Life-threatening within minutes
  • Treatment: Tourniquet (extremities) or wound packing (junctional)
  • Priority: IMMEDIATE action required

Venous Bleeding:

  • Appearance: Dark red/maroon blood
  • Pattern: Steady flow (not pulsing)
  • Severity: Can be life-threatening
  • Treatment: Direct pressure, pressure dressing, wound packing
  • Priority: Rapid action required

Capillary Bleeding:

  • Appearance: Oozing, slow seepage
  • Pattern: Continuous but slow
  • Severity: Usually minor, can be significant with large surface area
  • Treatment: Direct pressure, basic bandaging
  • Priority: Standard first aid

Tourniquet Application

When to Use a Tourniquet

Indications:

  • Life-threatening bleeding from extremity (arm or leg)
  • Amputation (partial or complete)
  • Bleeding not controlled by direct pressure
  • Multiple wounds where direct pressure is not feasible
  • Tactical situation (under fire, cannot maintain pressure)

Key Principle: If you are debating whether to apply a tourniquet, it is probably time to apply it. Better to apply unnecessarily than too late.

Step-by-Step Tourniquet Application

Step 1: Expose the Wound

  • Cut away clothing to see the injury
  • Identify bleeding source (arterial spurting = immediate tourniquet)
  • Do not waste time removing clothing—cut it

Step 2: Identify Application Site

  • Ideal: 2-3 inches above wound (between wound and heart)
  • Avoid: Over joints (elbow, knee)—tourniquet will not compress artery
  • If wound location unclear: High and tight (as high on limb as possible)

Step 3: Apply Tourniquet

  • Slide tourniquet under limb
  • Pull strap through buckle
  • Tighten strap as much as possible by hand
  • Secure Velcro (but this alone will not stop bleeding)

Step 4: Twist Windlass

  • Grab windlass rod (the stick)
  • Twist clockwise until bleeding STOPS COMPLETELY
  • This will be painful for conscious patient—expect screaming
  • Continue twisting until no blood flow distal to tourniquet
  • Check: No pulse below tourniquet, skin pale/cool

Step 5: Secure Windlass

  • Lock windlass in retention clip
  • This holds the tension—critical for continued hemorrhage control

Step 6: Record Time

  • Write application time on tourniquet time strap
  • Or write on patients forehead with marker
  • Format: TK 1435 (tourniquet applied at 2:35 PM)
  • This information is critical for hospital care

Step 7: Do NOT Remove

  • Once applied, tourniquet stays on until surgical care
  • Removing can release toxins and cause death
  • Even if bleeding appears stopped, do not loosen

Wound Packing

When to Pack Wounds

Indications:

  • Bleeding from areas where tourniquets do not work (neck, armpit, groin)
  • Deep wounds with significant bleeding
  • Junctional wounds (where limb meets torso)
  • Wounds not controlled by direct pressure alone

Step-by-Step Wound Packing

Step 1: Don Gloves

  • Protect yourself from bloodborne pathogens
  • If no gloves available, use plastic bag as barrier

Step 2: Expose and Assess

  • Cut away clothing
  • Identify wound depth and bleeding source
  • Remove any loose debris (do not dig for embedded objects)

Step 3: Pack from Bottom Up

  • Insert gauze into wound cavity
  • Push gauze deep—fill from the bottom
  • Do not just stuff the opening
  • Use hemostatic gauze if available (regular gauze works too)

Step 4: Fill Completely

  • Pack until wound cavity is FULL
  • No empty space remaining
  • Gauze should be tight, not loose

Step 5: Apply Pressure

  • Use both hands if possible
  • Apply firm, continuous pressure for 3+ minutes
  • Do not peek to check—this disrupts clotting
  • Set timer if available (3 minutes feels long under stress)

Step 6: Secure Dressing

  • Wrap with pressure bandage (Israeli, OLAES, or elastic wrap)
  • Maintain pressure while wrapping
  • Bandage should be tight but not cutting off circulation

Step 7: Monitor

  • Check for bleeding through dressing
  • If bleeding continues, add more gauze on top
  • Do not remove original packing (disrupts clot)

Conclusion

Bleeding control is the most critical emergency medical skill you can learn. A tourniquet applied correctly within 2 minutes of injury can be the difference between life and death.

The essentials:

  1. Carry a tourniquet (CAT or SOF-T Wide, not cheap knockoffs)
  2. Learn to pack wounds (hemostatic gauze + pressure)
  3. Take a Stop the Bleed course (hands-on practice is irreplaceable)
  4. Build a trauma kit (minimum IFAK, ideally family kit)
  5. Practice before you need it (muscle memory under stress)

You cannot train too much for this. The few hundred dollars and few hours spent on training could save your life or someone you love.

Discussion Questions

1. Do you carry a tourniquet daily? Which model? Where do you keep it?

2. Have you taken Stop the Bleed training? What was your experience? Would you recommend it?

3. What is in your trauma kit? IFAK, family kit, or something else? What would you add/remove?

4. Have you ever had to use bleeding control in real life? What happened? What did you learn?

5. What medical topics should we cover deeper? Wound care/infection prevention? Chest injuries? Airway management? Pediatric emergencies?
