Bleeding and Shock

Obj: I will identify types of bleeding

Obj: I will investigate types, signs and symptoms, and treatment for shock

What are the rules involving blood in sports?

Blood• Blood is the only

tissue that flows throughout the body

• Carries oxygen & nutrients to all parts of the body

• Transports waste products back to the lungs, kidneys, and liver for disposal

• Essential part of immune system

• Crucial for fluid and temp balance

• Hydraulic fluid for certain functions

• Highway for hormonal messages

Bleeding

• Arterial Bleeding– Issues bright red blood that

spurts or pulses corresponding to heart beat

• Venous Bleeding– Slower, less severe non-

pulsing bleeding– Closer to surface, therefore

easier to control

• Capillary Bleeding– Slow & oozing blood– Blood clots rapidly– Greater risk of infection

Arterial Bleeding

• Most serious• Punctured/severed artery• Bright red blood• Distinct spurts/pulses

correspond to heart beat• Can lose large volume of

blood in short period

Treatment:• Treat athlete for shock• Apply direct pressure;

find and use pressure points

• Call EMS• Apply tourniquet if

bleeding cannot be controlled by direct pressure or use of pressure points

Venous Bleeding

• Rupture of 1+ veins• Less severe than

arterial• Steady blood flow• Darker red blood• Easier to control

Treatment:• Direct pressure• Compression

bandaging• Follow-up with doctor

Capillary Bleeding

• Slow• Typically oozes• Blood clots quickly• Examples:

– Scratches– Minor cuts– Abrasions

Treatment: • Clean with soap and

water• Bandage

SHOCK

• Precursor to death• Occurs when the circulation system fails to send

blood to all body parts• Prompt recognition, treatment,

& control are crucial for survival

• Characterized by:– Drop in blood pressure– Reduced blood circulation– Inadequate blood flow to tissueshttps://www.youtube.com/watch?v=14--NBvGDjk

Hemorrhagic Shock• Loss of blood from an

injury• Blood pressure falls

and adequate oxygen is unavailable to body

• Injury internal or external

• Cause by severe blunt trauma or internal injuries (i.e. ruptured spleen)

Anaphylactic Shock• Caused by severe allergic

reaction (exaggerated response by body’s immune system to what would otherwise be a harmless substance)

• Reactions vary—itchy eyes and runny nose, to life-threatening response

• Insect stings, medications, certain food and food additives

Psychogenic Shock• Physiological response to

fear, stress, or emotional crisis

• Causes person to faint• Sudden temporary

dilation of blood vessels reduces normal blood volume to brain

• Temporary

Metabolic Shock• Occurs with severe

loss of body fluids• Severe diarrhea,

vomiting, or some disease

• Severe dehydration

Signs and Symptoms

• Restlessness and anxiety

• Cold and clammy skin• Labored or rapid

breathing• Profuse sweating• Face that becomes

pale and my eventually become cyanotic (blue) around the mouth

• Shallow respirations• Dull, lusterless eyes

with dilated pupils• Thirst• Nausea and vomiting• Blood pressure that

falls gradually and steadily

• Loss of consciousness

Treatment for Shock

• Maintain a clear airway so breathing is not impaired

• Control all bleeding• Elevate extremities 12 inches to help control

swelling• Splint fractures and elevate if well stabilized• Avoid rough and excessive handling that my

cause additional injury• Prevent loss of body heat; blanket should be

placed under victim as well as on top

Treatment for Shock

• Keep victim in supine position

• Do not give victim anything to eat or drink

• Record vital signs (pulse, blood pressure, respiration rate) every 5 minutes

• Constantly reassure victim; keeping victim calm minimizes effects of shock

• Activate EMS; call 911 immediately
