2. Shock, Wounds and Bleeding
Shock occurs when there is a drop in the supply
of oxygen to the body tissues due to in sufficient
circulation. Causes of shock can include:
bleeding, plasma loss due to burns, fluid loss
due to dehydration, vomiting, diarrhoea,
reduced pumping ability of the heart, pooling of
the blood in the peripheral vessels and
emotional trauma.

3. Shock, Wounds and Bleeding
Signs and Symptoms
• Rapid or weak pulse
• Pale, cool, sweaty skin
• Rapid, shallow breathing
• Feeling dizzy or light headed

5. External Bleeding
• Bleeding is the escape of blood outside the veins,
arteries and capillaries, caused by damage or a rupture.
• It is important to control any bleeding and limit the
amount of blood loss as quickly as possible. Large
amount of blood loss can be life threatening. External
bleeding is usually easily to see. The best way to
control bleeding is to apply direct pressure to the
wound site.
• When controlling bleeding from a casualty ensure you
follow the standard precautions to reduce the risk of
cross infection.

6. External Bleeding
Signs and Symptoms

sterile or clean pad where possible)
• If there is nothing available, use your hands to apply pressure

• Give oxygen if available and safe to do so
• Seek medical aid

8. Embedded object in wound
• If there is an object embedded in the wound,
it may not be possible to apply direct pressure
on to the wound to control bleeding. You will
need to apply indirect pressure around the
wound to slow the flow of blood and assist in
the natural clotting process.

9. Embedded object in wound
Steps to assist casualty
• Identify location and size of the wound
• Do not remove the embedded object
• Use pads, dressing and bandages to apply and maintain
pressure around the object
• Call ambulance
• Elevate wound if possible

Steps to assist casualty
• Casualty
– Control the bleeding by applying direct pressure to
the injured area
– If possible elevate the area
– Call ambulance
– Reassure the casualty
– Treat them for shock
– Monitor and record their vital signs
– Give oxygen if available and safe to do so

15. Amputations
• Amputated part
– Keep the part as clean, cool and dry as possible
– If possible:
– Put part in clean plastic bad
– Inflate and seal bag
