									Principles of Providing First Aid

Immediate care that is provided to the victim of injury or
illness to minimize the adverse effects until experts take
over.


Proper first aid can mean the difference between life
and death.


When you encounter an emergency:


                      REMAIN CALM

                       Avoid panic
                       Evaluate the situation
                       What you will do depends on
                        the type of injury, environment,
                        others present, etc. – so THINK
                        before you act




                        Summer 2000 G.1
The first step is to be alert to the signs of an
emergency:

                                         Screams
                                         Calls for help
                                         Breaking glass
                                         Screeching tires
                                         Empty medicine
                                          bottle
                                         Damaged electrical
                                          wires
                                         Smoke or fire
                                         Blood
                                         Spilled chemicals
                                         Difficulty
                                          breathing
                                         Clutching chest or
                                          throat
                                         Abnormal skin

                                         Distress




                    Summer 2000 G.2
             Once you determine an emergency
             exists, take steps to help the victims:


1.   Check the scene and make sure it is safe to
     approach.

2.   IF the scene is not safe, call for medical help – do
     not endanger yourself or others.

3.   IF the scene is safe, approach the victim and
     determine consciousness by gently tapping and
     calling to him/her.

4.   Never move an injured victim unless the victim is in
     danger.

5.   Call the EMS as soon as possible – 911.

6.   Be prepared to describe location, telephone number
     (where you are calling from), assistance required, #
     of people involved, etc.

7.   Try to obtain victim’s permission before providing
     care. (If parent is present and victim a child, get
     parent’s permission.)


                         Summer 2000 G.3
8.   If person refuses care, do not proceed. If possible,
     have someone witness the refusal of care.

9.   Always attend to life threatening emergencies first.

10. If victim conscious, breathing and able to talk,
    reassure the victim and try to determine what
    happened.

11. Check for injuries – examine the victim thoroughly
    and note any abnormal signs or symptoms.

12. Report abnormalities when EMS arrives.

13. Obtain as much information as possible regarding
    the incident and give the information to the correct
    authorities.

                        Summer 2000 G.5
Providing First Aid for
Bleeding and Wounds

Wound
 Injury to soft tissue
 Open: Break in the skin or
  mucous membrane
 Closed: No break in skin, injury to underlying tissues
 Opening wounds can result in bleeding, infection, or
  tetanus
 First aid directed toward controlling bleeding and
  preventing infection

Abrasion - skin scraped off, bleeding limited

Incision – cut with sharp object such as knife, scissors,
razor blade, etc., if cut is deep, bleeding can be heavy,
also can have damage to muscles and nerves.

Laceration – tearing of tissues from excessive force,
jagged edges, bleeding may be heavy. Deep lacerations
may become infected.




                        Summer 2000 G.6
Puncture – Caused by sharp object (pin, nail, etc.)
External bleeding minimal, may lead to infection or
tetanus.

Avulsion – Tissue torn or separated from the body,
bleeding is heavy, important to preserve the body part
because a surgeon may be able to reattach it.

Amputation – Body part cut off or separated from the
body, bleeding can be extensive, important to preserve
separated part for reattachment. Wrap part in cool, moist
dressing (sterile water or saline preferred) and place in
plastic bag. Keep bag cool or in ice water and transport
with the victim. (Don’t place
the body part in direct
contact with the ice.)




                       Summer 2000 G.7
Control Bleeding


        First Priority – Control the bleeding!


Arterial bleeding is bright red in color and life
threatening.

Venous bleeding is slower and dark red.

Control bleeding by:
1. Direct pressure
2. Elevation
3. Pressure bandage
4. Pressure points


          Use protective barrier to control bleeding
          (gloves) or thick layers of dressings. Avoid
          direct contact with blood. Wash hands after
          providing first aid.




                         Summer 2000 G.8
Infection

Signs and symptoms of wound infection:

   Swelling
   Heat
   Redness
   Pain
   Fever
   Pus
   Red streaks

Tetanus – bacterial infection, most common in puncture
wounds, be sure to find out when victim last had tetanus
shot, advise to consult medical professional about tetanus
booster.

Object in wound? If on the surface, remove with
tweezers. If object embedded, let a physician remove it.

Closed wounds
 If a bruise, apply cold
 Signs of internal bleeding – pain, tenderness, swelling,
  deformity, cold and clammy skin, rapid and weak
  pulse, uncontrolled restlessness, excessive thirst,
  vomiting blood, blood or urine in feces.



                        Summer 2000 G.9
Shock

When caring for bleeding/wounds, or any other injury or
illness, be alert for signs of shock.

                  Clinical set of signs and symptoms
                  associated with inadequate supply of
                  blood to body organs, especially the
                  brain and heart.


If not treated, shock can lead to death, even when the
victim’s injuries or illness not life threatening.

Shock caused by:
 Hemorrhage
 Excessive pain
 Infection
 Heart attack
 Poisoning by chemicals, drugs or gases
 Lack of oxygen
 Psychological trauma
 Dehydration from burns, vomiting, or diarrhea




                       Summer 2000 G.10
Symptoms:
 Skin pale or cyanotic
 Skin cool to touch
 Diaphoresis

  unconscious
 Victim anxious and extremely restless
 Victim may complain of excessive thirst
 Victim may experience nausea and vomiting
 Victim may complain of blurred vision – as shock
  progresses, eyes may appear sunken and have vacant,
  confused expression, pupils dilate

Get medical help right away. If possible:
1. Eliminate the
   cause of shock
2. Improve
   circulation to the
   brain and heart
3. Provide oxygen
4. Maintain body
   temperature


Positioning patient depends on injuries:

                       Summer 2000 G.11
IF NECK OR SPINAL INJURY SUSPECTED
– do not move the victim.

How would you position the following
victims when treating for shock?


 Victim has a broken arm, no other apparent
  injuries.

 Victim is vomiting and bleeding profusely
  from a lacerated tongue.

 Victim has broken rips and is dyspneic

Cover the patient with blankets or additional clothing.
Blankets may also be placed between the ground and the
victim.

Avoid giving the patient anything to eat or drink. A wet
cloth may be used to moisten the lips and mouth.

If help won’t arrive for more than an hour and
dehydration is evident, provide fluids.
Poisoning


                       Summer 2000 G.12
If poison ingested, call a poison control center (PCC) or
physician immediately. If not available, call the EMS.

Save the label or container of the substance taken.

It is helpful to know/estimate how much was taken and
the time the poisoning occurred.

If the victim vomits, save a sample.

IF THE VICTIM IS UNCONSCIOUS – check for
breathing. Provide rescue breathing if the victim is not
breathing. If victim is breathing, turn victim on his/her
side.

If the poison control center tells you to induce vomiting:
 Give syrup of ipecac.
 Tickle the back of the victim’s throat.
 Administer warm salt water.




DO NOT induce vomiting if:

 The victim is unconscious.
 The victim swallowed acid or alkali.

                        Summer 2000 G.13
 The victim swallowed petroleum.
 The victim is convulsing.
 The victim has burns on the lips or mouth.

Vomiting only removes ½ the poison, so
you may need to administer activated
charcoal to counteract the remaining
poison.

If poisoning is due to gas inhalation….remove victim
from area.

Carbon Monoxide Poisoning
 Odorless and colorless gas
 Before entering the area, take a deep breath and don’t
  breathe the gas while removing the victim from the
  area.
 After the rescue, check for breathing and administer
  CPR if needed.
 Obtain medical help immediately.




Chemicals or Poisons that come in Contact with Skin
 Wash with large amounts of water
 Remove clothing or jewelry that contains the substance

                       Summer 2000 G.14
 If poisonous plant, wash with soap and water – use
  Calamine or Caladryl (or paste made from baking soda
  and water.)
 Obtain medical help

For insect bite, sting or snakebite…
 If possible, hold part below level of the heart
 Remove the stinger and wash the area with soap and
 water
 Apply sterile dressing & cold pack
 Monitor the victim and give CPR if needed
 Watch for allergic reaction
 Treat for shock
