Pressure Bandage: When to Use Each for Bleeding Control

Pressure bandages are essential tools in managing bleeding and promoting proper wound healing. Understanding when and how to use different types of pressure bandages can be crucial in emergency situations and everyday first aid. This comprehensive guide will explore various pressure bandages, their applications, and the best practices for bleeding control.

Understanding Pressure Bandages

Pressure bandages are designed to apply consistent pressure to a wound, helping to control bleeding effectively[1]. These specialised dressings play a vital role in first aid and emergency medical care, serving multiple purposes:

• Control bleeding
• Encourage blood clotting
• Minimise swelling
• Protect wounds from contamination
• Prevent additional trauma to the injured area
• Reduce heat and fluid loss

Pressure bandages come in various forms, each suited for specific situations and wound types. Let’s explore the different types of pressure bandages and when to use them for optimal bleeding control.

Advanced Techniques for Pressure Bandage Application

When it comes to pressure bandages, mastering advanced techniques can make a significant difference in bleeding control effectiveness. Let’s explore some sophisticated methods for applying pressure bandages in various scenarios.

Spiral Technique

The spiral technique is particularly useful for cylindrical body parts like arms and legs. This method ensures even pressure distribution and secure coverage.

Steps:

1. Start by anchoring the bandage with a couple of circular turns
2. Progress up the limb at a 45-degree angle, overlapping each turn by about two-thirds
3. Continue until the entire area is covered
4. Secure the end with tape or clips

Pro tip: For areas with varying circumferences, such as the forearm, use figure-eight turns to prevent gaps in coverage.

Figure-Eight Technique

The figure-eight technique is ideal for joints like knees and elbows, providing flexibility while maintaining pressure.

Steps:

1. Begin below the joint with a circular turn
2. Move upward diagonally across the joint
3. Make a circular turn above the joint
4. Return diagonally downward, crossing the previous diagonal
5. Repeat the pattern, overlapping each turn slightly
6. Finish with a circular turn and secure

Key point: This technique allows for joint movement while keeping the bandage in place, crucial for patient comfort and mobility.

Pressure Points Technique

For severe bleeding, combining pressure bandages with manual pressure on specific pressure points can enhance bleeding control.

Key pressure points:

• Brachial artery (inner upper arm) for arm injuries
• Femoral artery (groin area) for leg injuries
• Carotid artery (neck) for head and neck injuries (use with extreme caution)

Application:

1. Locate the appropriate pressure point
2. Apply firm pressure with your fingers or palm
3. Simultaneously apply the pressure bandage to the wound
4. Gradually release pressure on the pressure point as the bandage takes effect
