In a Disaster there are

3 Phases of Trauma Death:

Phase 1: Death in Minutes

Phase 2: Death in Hours

Phase 3: Death in Days to Weeks

Phases of Trauma Deaths

Peter Safer’s Research:

40 percent of disaster victims in the

second and third phases of death from

trauma could be saved by providing

simple medical care.

“Bleeding Control”

The average adult has between 5-6 liters of blood in their body.

Losing one liter can result in death.

Anatomy / Physiology

There are 3 types of blood loss:

Capillary Venous Arterial

Blood Loss

There are 3 methods to control blood loss:

1. Direct Pressure

2. Elevation

3. Pressure Points

Controlling Blood Loss

Direct Pressure

Placing pressure directly over the wound, using a clean dressing.

Followed by a pressure bandage.


Elevation

Placing the wound above the level of the heart.

It can take 5-7 minutes to stop the bleeding using Direct Pressure and Elevation.


Pressure Points

A pulse point for a major artery.

- Brachial point

- Femoral point

Put pressure with your hand at the proximal pressure point.


Tourniquet

A “Last Resort”

Leave in plain sight

Mark the patient’s forehead with “T” and time it was applied

Only a physician should remove

“Recognizing & Treating for Shock”

• Shock is a disorder from ineffective circulation of blood.

• In a disaster situation, this ineffective circulation of blood usually results from uncontrolled bleeding.

Definition of Shock

• The loss of blood volume will ultimately lead to the death of cells, tissue, & entire

organs.

Definition of Shock

• Rapid, shallow breathing

• Capillary refill >2 sec.

• Unable to follow simple commands

• Skin color & temperature

Signs of Shock

Capillary Refill

• Lay victim on his back

• Elevate feet 6 – 10”

• Control obvious bleeding

• Maintain body temperature

• Avoid rough handling

Action Steps for Treating Shock

Purpose: This exercise allows you to practice the steps for treating shock.


with their eyes closed.2. The rescuer should treat the victim based on the

scenario given by the instructor.

The rescuer and the victim should switch roles.

“Splinting”

Treating Fractures, Dislocations, Sprains, and Strains

Immobilize the injury and joints above and below the injury site.

If questionable, treat as a fracture.

ObjectivesObjectives

Treating Fractures, Dislocations, Sprains, and Strains

A CLOSED FRACTURE is a broken bone with no associated wound.

First aid treatment for closed fractures may require only splinting.

Fractures

An OPEN FRACTURE is a broken bone with some kind of wound that allows contaminants to enter into or around the fracture site.

Fractures

Open fractures are more dangerous because of the risk

of severe bleeding and infection. Therefore, they are a higher priority and need to be checked more frequently.

Treating an Open Fractures

DO:

Cover wound.

Splint fracture

without disturbing wound.

Place a moist 4" x 4" dressing over bone end to prevent drying.

DO NOT:

Do not draw

exposed bones back into tissue.

Do not irrigate wound

Displaced Fractures

DISPLACED

fractures in which the fractured bones are no

longer aligned.

Non-Displaced Fractures

NON-DISPLACED

fractures in which the fractured bone remains aligned.

Dislocations

DISLOCATION:

an injury to the ligaments around a joint that permits a separation of the bone from its normal position in a joint.

Dislocations

Signs of a dislocation are similar to those of a fracture….

A suspected dislocation should be treated like a fracture.

Dislocations

Never try to relocate a suspected dislocation.

Immobilize the joint until professional medical help is available.

Sprains

A sprain involves a stretching or tearing of ligaments at a joint

Is usually caused by stretching or extending the joint beyond its normal limits.

Signs of Sprain

Tenderness at injury site

Swelling and/or bruising

Restricted use or loss of use

Immobilize and elevate.

Strains

Stretching and/or tearing of muscles or tendons.

Most often involves the muscles in the neck, back, thigh, or calf.

May be difficult to distinguish from sprains or fractures.

Strains

When uncertain whether an injury is a strain, sprain, or fracture, treat the injury as if it is a fracture.

Splinting

Splinting is the most

common procedure

for immobilizing an

injury.

Cardboard is the material typically used for “makeshift” splints but a variety of

materials can be used, including:

Splinting

Splinting using a towel, in which the towel is rolled up and wrapped around the limb, then tied in place.

SOFT MATERIALS: Towels or blankets tied with

bandaging materials or soft cloths.

Splinting

Pillow splint, in which the pillow is

wrapped around the limb and tied.

SOFT MATERIALS: Pillows tied with bandaging

materials or soft cloths.

RIGID MATERIALS:

Using a board, metal strip, folded magazine or newspaper, or other rigid item.

Splinting

ANATOMICAL SPLINTS:

Created by securing a fractured bone to an adjacent un-fractured bone.

Splinting using a blanket in which the victim’s legs are

immobilized by tying blankets at intervals from

mid-thigh to feet.

Splinting

Guidelines for Splinting

Support the injured area above and below the site of the injury,including the joints.

If possible, splint the injury in the position that you find it.

Don’t try to realign bones or joints.

Guidelines for Splinting

After splinting, check for proper circulation (warmth, feeling, and color).

Immobilize above and below the injury.

“Burns & Hypothermia”

4 Major Sub-functions

TRIAGE: The initial assessment and sorting of victims for treatment based on the

severity of their injuries.

TREATMENT: The area in which disaster medical services are provided to victims.

TRANSPORT: The movement of victims from the Triage area to the Treatment area.

MORGUE: The temporary holding area for victims who have died as a result of their injuries.

Treating Burns

Two Objectives:

1. Cool the burned area

2. Cover with sterile cloth to reduce the risk of infection

Treating Burns

Severity of a Burn depends on:

1. Temperature of the Burning agent

2. Length of exposure

3. Area of body affected

4. Size of the area Burned

5. Depth of the Burn
