Circulatory System
Aorta
Largest artery in the
body
Arteries
Strong muscular, elastic walls
enable arteries to expand
with each surge of blood
away from the heart and
towards tissues
Veins
Action of muscles around
these thin walled vessels
squeezes blood through
them, and one-way valves
keep it from flowing back
towards the heart

Universal Precautions for Airborne
& Bloodborn Pathogens
HIV & Hepatitis
Tuberculosis
Gloves & Respiratory
Barrier devise are a must to
prevent transmission of
diseases
DURING TREATMENT
avoid coughing, breathing, or speaking over the
wound
avoid contact with body fluids
use a face shield or mask with one-way-valve
when doing active resuscitation
use only clean bandages and dressings
avoid treating more than one casualty without
washing hands and changing gloves
AFTER TREATMENT
clean up both casualty and yourself
clean up the immediate vicinity
dispose of dressings, bandages, gloves and
soiled clothing correctly
wash hands with soap and water

Life-Threatening Emergencies
1. The person has stopped breathing
2. The person has no heartbeat
3. The person is bleeding severely
4. The person is choking
5. The person has swallowed poison
6. The person has been severely burned
Rescue Breathing
A substitute for normal breathing in which
someone forces air into the victim’s lungs.
1. Listen close to the victim’s nose and mouth
2. Tilt the head back to open the airway
Rescue Breathing
3. Pinch the nose shut and give two slow
breaths. The chest should rise with each
breath
4. If the victim begins to breath normally stop
Cardio Pulmonary
Resuscitation
an emergency procedure consisting
of chest compressions often
combined with artificial ventilation in
an effort to manually preserve intact
brain function until further measures
are taken to restore spontaneous
blood circulation and breathing in a
person who is in cardiac arrest.
22
Principles of Resuscitation
For life to be sustained,:
A constant supply of oxygen must be
maintained and delivered to the brain and
other vital organs by circulating the blood.
The “pump” that maintains this circulation:
Is the heart. If the heart stops (cardiac arrest)
urgent action must be taken if death is to be
prevented.

Reaction Time
If CPR/Artificial respiration is administered
Chance of brain damage
0 to 4 minutes -
4 to 6 minutes -
6 to 10 minutes-
10 minutes + -
Recovery rate of
victim if has
artificial
respiration done
immediately
Oxygenated
blood flow
must get to
brain
A-B-C’s
Use chin lift/head tilt
Look.-listen-feel for breathing
Attempt to Ventilate
Ventilate Every 5 seconds
• Establish responsiveness
Check pulse Recovery position

Hands Only CPR
1. Be sure 911 has been called!
2. Keep the neck and head in proper alignment.
3. Gently guide the victim/patient to the floor and elevate the legs
by placing a blanket or pillow under the legs.
4. Tap on the shoulder and shout,
“Are you okay?” and
quickly look for breathing.
5. If unresponsive and not breathing,
BEGIN CHEST COMPRESSIONS!
CONNECTICUT STATE DEPARTMENT OF EDUCATION
How to do Chest Compressions
1. Place the heel of the other hand on top of the first hand, lacing
your fingers together.
2. Place the heel of one hand on the center of the chest.
3. Keep your arms straight, position your shoulders directly over
your hands.
4. Push hard, push fast:
• Compress the chest at least 2 inches;
• Compress at least 100 times per minute;
• Let the chest rise completely before
pushing down again.
CONNECTICUT STATE DEPARTMENT OF EDUCATION
When to Stop Chest Compressions
Do Not Stop Except in one of these situations:
• You see an obvious sign of life (breathing);
• Another trained responder arrives and takes over;
• EMS personnel arrive and take over;
• You are too exhausted to continue;
• An AED is ready to use; or
• The scene becomes unsafe.

First Aid for Severe Bleeding
Wear gloves if possible and wash you hands
after
Sit or lay the victim down
Elevate the wound above the heart
Apply direct pressure with a clean cloth
Wrap the wound
Apply pressure to the artery
Get them professional treatment
34
Dressings & Bandages: Uses
Dressings
Control bleeding
Reduce infection
Bandages
Direct pressure
Securing dressings etc
Reduce swelling, support limbs
Restrict movement
34
Tourniquet
Absolute last resort in
controlling bleeding
Remember - Life or limb
Once a tourniquet is
applied, it is not to be
removed , only by a
doctor
First Aid for Choking
Know universal sign for choking
Ask “are you choking”
First Aid for Choking
Use abdominal thrusts- upward pulls into
the diaphragm to force out the object

First Aid for Choking
For an infant you will give them 5 back
blows and five chest compressions. Using
fingertips on breastbone
If they become unconscious call 911
