Chapter 9
First Aid
Secondary Assessment
Warm-up
• What it’s the ratio between chest compressions and breathes for adult, child, and infant two man CPR?
Lesson Objectives….• Demonstrate how to perform a secondary
assessment.
• Recognize and care for a victim of a sudden illness.
• Recognize and care for wounds.
• Recognize how to control external bleeding.
• Recognize and care for shock.
• Recognize and care for heat- and cold-related emergencies.
Secondary Assessment
• After completing the initial assessment and determining that there are no life-threatening conditions, perform a secondary assessment.
• During a secondary assessment , perform a quick head-to-toe examination for an adult
• Toe-to-head exam for an child/infant
Using SAMPLE to take a brief history pp.142-143• S- signs & symptoms
• A - allergies
• M- medications
• P- pertinent past medical history
• L- last oral intake
• E- events leading up to incident
SUDDEN ILLNESS
• Diabetic emergency
• Fainting
• A seizure
• A stroke
• Allergic reaction
• Poisoning
Sudden illness continued…• It is not important to know
the cause or type of sudden illness because the care you provide will be the same with a few exceptions.
• If you think something is wrong, check the victim and look for a medical identification bracelet or necklace.
• The victim’s condition can worsen rapidly if care is not provided.
Diabetic Emergency
• Too much or too little sugar in their blood
• Often, diabetics know what is wrong and will have something to take
• Give sugar, preferably in liquid form
Seizures
• Provide care in the same manner as for an unconscious victim. Protect the victim from being injured, remove nearby objects that might cause injury.
• If there is fluid in the victim’s mouth (saliva, blood or vomit) roll victim on one side so that the fluids drain from the mouth.
Seizures continued…
• If the victim is known to have periodic seizures, there is no need to summon EMS. Unless…
• The seizure last more than 5 minutes
• Multiple seizure• Appears to be injured• Victim is pregnant• Victim is diabetic• Fails to regain
consciousness• Occurs in water
Seizures in the Water
• Summon or have someone summon EMS
• Support the victim with his or head above water until seizure ends.
• Remove the victim from the water ASAP after the seizure.
• Place the victim face-up on the deck and perform an initial assessment and care.
Stroke
• Signs: weakness/numbness of the face, arm or leg (usually on one side)
• To care think FASTFace- weakness on one side
of face
Arm-weakness/numbness in one arm
Speech- slurred or troubled
Time- time to summon EMS
Bites & Stings p. 147
• Spider/scorpion• Snakebites • Marine Life
– Jellyfish– Crabs– Stingray
WOUNDS
• An injury to the body’s soft tissue, such as the skin, fat and muscles.

Cuts, Scrapes, & Bruises
• Blood- 60,000 miles of blood vessels
• Heart
• Arteries
• Veins
• Capillaries
Stitches
• Uncontrollable bleeding
• Wounds that show muscle, bones, joints
• Large and deep puncture wounds
• Embedded objects
• Human / animal bites
Types of Wounds
• Contusion (bruise)
• Abrasion (scrape)
• Incision (cut / laceration)
• Avulsion
• Puncture
Contusion (Bruise)
• Damage to soft tissues & blood vessels causes bleeding under the skin
• At first it may appear red
• Turn purple
Scrape (abrasion)
• Most common type of wound caused by skin that has been rubbed or scrapped away
• Usually painful because scraping away of outer skin exposes nerve endings
Incision (cut / laceration)• May be jagged or
smooth edges• Commonly caused by
sharp objects• Can also be caused by
a blow from a blunt object
Avulsion
• A cut in which a portion of the skin or other soft tissue is partially / completely torn away
• May hang like a flap• Severed (finger)
Puncture
• Caused when a pointed object pieces the skin (nail, tack, bullet)
• An object that remains embedded in the wound is called an impaled object
Caring for Soft Tissue Injuries
• Closed Wound (internal injuries)• Apply something cold to control swelling• Signals of Internal Bleeding
– Tender, swollen, bruised
– Rapid / weak pulse
– Skin (cool, moist, pale, bluish)
– Vomiting / coughing up blood
– Excessive thirst
– Confused, faint, drowsy or unconscious
Caring for an Open Wound
• Control bleeding (sterile dressing-direct pressure)
• Raise / elevate above heart (if no broken bone is suspected)
• Apply bandage snugly over dressing (if bleeding does not stop apply additional dressing)
• If bleeding cannot be controlled, put pressure to supplying artery
Continued
• Call EMS
• Care for shock
• Wash hands after care
Shock
• Any serious injury or illness can result in shock.• Shock is a natural reaction by the body.• It usually means the victim’s condition is very
serious.• It is a life-threatening condition that occurs when
the body is not getting enough blood flow. This can damage multiple organs. Shock requires IMMEDIATE medical treatment and can get worse very rapidly.
Signals of Shock
• Restlessness / irritability
• Altered consciousness
• Nausea
• Pale, cool, moist skin
• Rapid breathing
• Rapid pulse
Caring for Shock
• Have victim lie down, elevate legs about 12” (unless you suspect head, neck, back injuries)
• Call 9-1-1• Control any external
bleeding• Help victim maintain body
temperature• Do not give food or drink• Reassure victim
Special Situations
• Severed body parts• Embedded objects• Injuries to the mouth• Animal and human
bites• Emergency childbirth
Severed Body Part
• Wrap the part completely in gauze or a clean towel.
• Wet the towel with cool water. • Place the wrapped body part in a plastic bag &
seal it shut.• Place the sealed bag in to another bag or bucket
filled with ice. • Take the bag with the amputated body part to
the hospital with the victim.
Embedded Objects
• Do not remove it• Place several objects
around object to support it
• Eye-cover both eyes
Organs that Break Through the Abdomen• Carefully remove clothing from around the
move
• Cover organs with a moist, sterile / clean dressing
• Cover dressing with plastic wrap
• Place a folded towel / cloth to keep warm
Burns
•
Burns• Are a specific type of soft tissue injury
• You can describe burns by their cause or by their depth (the deeper the burn, the more severe it is)
• A critical burn can be life-threatening
Burns are caused by:• Heat
• Chemicals
• Electrical current
• Radiation
What are Critical Burns?• Burns involving trouble breathing
• Burns covering more than one body part
• Burns to the head, neck, hands, feet or genitals
• Burns (other than very minor) to child/elderly
• Burns resulting from chemicals, explosions or electricity
Critical Burns• Life-threatening
• Seek immediate medical attention
• Often hard to tell how severe a burn is after it has happened
• Problem breathing
Types of Burns
Superficial (First Degree)
• Involve the first layer of skin
• Skin is red & dry & usually painful
• May be swollen
• Most sunburns are superficial
• Heals in 5-6 days without permanent scarring
Partial Thickness (Second Degree)
• Involves top layers of skin
• Skin is red & blistered that may open & seep clear fluid
• Usually painful & often swells
• Usually heals in 3-4 weeks
• Scarring may occur
Full Thickness (Third Degree)
• Destroys all layers of skin & any/all underlying structures (fat, muscle/bones,nerves)
• Burns look brown/black (charred) with tissue underneath appearing white
• Can be either extremely painful or relatively painless (nerve endings destroyed)
Care for Burns• Stop the burning
– Put out flames or remove victim from source of burn
• Call fast-serious burns
• Cool the burn– Use large amounts of water to cool– Do not use ice
Care for Burns Continued
• Cover the burn– Use dry, sterile
dressings– Loosely bandage them
in place (don’t put pressure on burn)
– Do not break blisters (unbroken skin helps prevent infection)
Minor Burns• Wash area with soap & water
• Keep clean
• Apply antibiotic ointment (Neosporin)
• Watch for infection
Severe Burns• Lay victim down-unless trouble breathing
• Raise areas above heart
• Chill easily- cover
Special Kinds of Burns
Chemical Burns• Chemicals (cleansers, lawn & garden
sprays, paint removers, bleach) come in contact with skin or eyes
• May cause severe burns (longer contact)
• Flush with large amounts of cool running water
• Remove clothing
Electrical Burns
• Never go near a victim of an electrical burn until you are sure the power source is turned off
• Caused by:– Power lines– Lightning– Defective electrical
equipment– Electrical outlets
Electrical Burns continued
• Severity depends on how long the victim was in contact with power source & strength & type of current & path it takes
• Often deep
• Two wounds-enter/exit
Radiation• Sun-may blister• Cool the burn• Stay out of the sun• Protective lotion
(SPF-15)• Antibiotic lotion-
prevent infection
Don’ts of Burn Care• Apply ice directly to any burn, unless it’s
very minor• Touch a burn w/ anything except clean
covering• Remove pieces of cloth that stick to
burned area• Try to clean a severe burn• Break blisters• Use any kind of ointment
Injury to Muscles, Bones & Joints
http://www.youtube.com/watch?v=_wxebhExcTk
Skeletal System
• Over 200 bones• Various sizes &
shapes• Protect the body &
help the body move• Hard & dense & have
a rich supply of blood/nerves
Joints
• Consist of 2 or more bones held together by ligaments
• All joints have a normal range of motion
• When joints are forced beyond this range, ligaments stretch/tear
Muscular System• 600 muscles-most
attached by strong tissue called tendons
• The shortening & lengthening of muscle make the body move
• Brain directs muscles to move through the spinal cord
• Injuries/diseases to the brain, spinal cord, or nerves can affect muscle control (stroke, parapalegic, Parkinsons)
Injuries
• Injuries to muscles, bones & joints happen often
• Happen to people of all ages
• Happen at home, at work, and at play
Four Basic Types of Injuries
• Fractures• Dislocations• Strains• Sprains
Fractures
• Complete break, chip or crack
• Closed
• Fractures can be life-threatening if they involve breaks in large bones, sever an artery, affects breathing
Fractures
• Open (compound)-bone breaks through the skin
Dislocations
• Is the movement of a bone at a joint from its normal position
• Usually more obvious than a fracture
• Usually tears ligament away from bone
• Forms a bump, ridge or hallow
Strains
• Stretching and tearing of muscles & tendons
• Usually caused by lifting something heavy or working muscle too hard
• Usually involve neck, back, thigh, calf
Sprain
• Tearing ligaments at a joint
• Mild sprains may swell, but usually heal quickly
• Severe sprain can involve a fracture/dislocation
• Joints easily injured-(ankle, knee, wrist, finger)
How can you tell how bad the injury is?• Pain (most common signal)
• Swollen, red or bruised
• Significant deformity-twisted or strangely bent
• Abnormal lumps or ridges
• Inability to use affected part normally
• Bone fragments sticking out of wound
Continued
• Feel bones grating, felt/heard a snap,pop at the time of injury
• Injured area is cold/numb
• Compare to uninjured leg or arm
• X-ray, MRI, CAT scan
Splinting
• Splint only when victim must be moved
• Only if you can do it without causing more pain
• Splint the injury in the position you find it
• Check circulation
Types of Splints
• Soft splints
• Anatomic splints
• Slings
• Rigid splints
Sprains & Strains
• General care (R.I.C.E.)
• Rest
• Immobilize
• Cold
• Elevate
• Cold then heat-reduces swelling and pain
Special Situations
Head & Spine Injuries
• 2 million each year• Mostly males 15-30
years old• Causes:
– Motor vehicle accidents (44%)
– Falls (22%)– Acts of violence (24%– Sports (8%) 2/3 from
diving
When to Suspect Head, Neck, & Back Injuries• A fall from a height greater than that of the victim
(elderly person)• Any diving mishap• Unconscious person (unknown reason)• Motor vehicle accidents where severe blunt
force to the head, chest, abdomen, or pelvic area (gun shot wound)
• Victim’s helmet is broken (motorcycle, bike, football, industrial helmet)
• Lightning strike or when a victim is thrown
Signals of Head, Neck & Back Injuries• Change in consciousness• Severe pain/pressure in the head, neck or
back• Tingling or loss of sensation (hands,
fingers, feet & toes)• Partial / complete loss of movement• Unusual bumps/depressions on
head/spine• Blood / fluids (ears / nose)
Signals continued
• Heavy external bleeding (head, neck, back)
• Seizures• Impaired breathing / vision• Nausea / vomiting• Persistent headache• Loss of balance• Bruising (head, eyes, behind the ears)
