Introduction
On your drive home you come upon an accident that has just occurred. Are you legally responsible to stop and help the victims?
If you do provide first aid, can you be sued if the patient is paralyzed or dies?
3
Introduction
You started first aid on the victims of the accident. You hear that there are sirens in the distance. Can you leave now because you hear that help is on the way?
One of the victims is bleeding very badly from his leg. He tells you not to touch him because he feels the bleeding is not that bad. You know this is a very serous injury. What do you do?

Definition
First Aid – immediate care given to a victim of an accident or illness to minimize effect of injury or illness until trained medical professionals can take over Not full & complete treatmentNot limited to physical treatment of victim
5
First Aid
Why provide first aid?Difference between life & deathDifference between recovery & permanent
disabilityHelp yourself & others in time of emergency
6
Principles of First Aid
Basic Principles of First AidRemain calmAvoid panicEvaluate situation thoroughly (“scene safety”)Treatment you provide will vary depending on
type of injury or illness, environment, equipment and supplies on hand & availability of medical help
7
Preparing To Administer First Aid
Recognize that an emergency existsUse senses to assist you
Hearing – screams, calls for help, breaking glass, changes in noises of machinery
Sight – empty medicine containers, damaged electrical wires, a stalled car, smoke, fire, blood
Smell – chemicals, natural gas, pungent fumes, unfamiliar odors
8
Preparing To Administer First Aid
After determining that emergency exists:Call for medical help immediately (9-1-
1)Time factor is critical Early EMS access increases survival rate
If instructing others to call:Describe situation, location, number of
victims
9
Preparing To Administer First Aid
After determining that emergency exists:Check scene to make sure it is safe to
approach (fuel spill, chemicals, power lines, fire, etc.)
Hundreds of untrained responders die every year because of their failure to check the scene
10
Preparing To Administer First Aid
After determining that emergency exists:Survey entire scene
What happenedDangers presentNumber of people involved
11
Preparing To Administer First Aid
If scene is NOT safe:Do NOT proceedCall for medical help immediatelyInform others in area of hazard
12
Administering First Aid
Once you determine scene is safe:Approach victim(s)
Determine if victim is conscious Tap gently, call out to them
If victim is conscious find out what happened and where they are injured
Be brief; Assess orientation to person, place, time and incident (A & O x4)
13
Administering First Aid
A & O x4Person
“What’s your name?” (Introduce self as well.)
Place“Do you know where you are?”
Time“What year is it?” “What day is it?” “What
month is it?”
14
Administering First Aid
A & O x4Incident
“Can you tell me what happened?”
Obtain patient’s permission before touching them or rendering treatment of any kind.
15
Administering First Aid
NEVER move a victim unless:The victim is in a dangerous area such
as an area filled with fire, smoke, flood waters, carbon monoxide, dangerous traffic where vehicles may not see victim
16
Administering First Aid
IF you have to move the victim:Move victim quickly and carefullyNOTE: Victims have been injured more
severely by improper movement, so avoid all unnecessary movement
17
Administering First Aid
If you are alone, make certain you speak to EMS before providing care for:Unconscious adultUnconscious child 8 years old or olderUnconscious infant
18
Administering First Aid
If victim is unconscious, confused, or seriously ill and unable to consent to treatment, and no other relative is present, you can assume that you have permission to render aid.
Patients have the right to refuse care!
19
Administering First Aid
If patient refuses care:Do NOT proceed!If possible have someone witness
refusalIf situation is life threatening, update
EMS immediately
20
Triage
Triage: method of prioritizing treatmentIf you have two or more victims, triage
also determines who gets treated first, and who can wait for treatment
21
Triage
Always care for life-threatening injuries FIRST!No breathing or difficulty breathingNo pulseSevere bleedingChest painAbdominal painVomiting or passing bloodPoisoning
22
Triage
Always care for life-threatening injuries FIRST!Head injuriesNeck or Spinal injuriesOpen chest or abdominal woundsShockSecond or third degree burns
23
Triage
If victim is conscious:Provide reassuranceTry to determine what happenedMechanism of injuryExamine the victim thoroughly
Always have a reason for what you doAsk the victim about pain & discomfort
24
Triage
Check for other injuries:Broken bonesBurnsShockNote any abnormal signs/symptomsCheck vital signs (pulse/respiration/temp?)Note temperature, color & moistness of skinCheck & compare pupils
25
Triage
Check for other injuries:Look for fluids or blood
draining from mouth, nose, or ears
Examine the body for cuts, bruises, swelling & painful areas
26
Triage
Report any abnormalities to EMSObtain as much information as possible
(patient may have a change of status)Give information gathered to correct
authorities onlyLook for medical identification bracelets,
necklacesMental picture of surroundings
27
Triage
Mental picture of surroundingsDo NOT give patient anything to eat or drink, unless
the situation absolutely warrants it (dehydration, hypoglycemia)
Protect victim from extreme cold or heatDo NOT diagnose victim or make predictions
about their outcomeMaintain confidentiality at all times
28
Triage
Mental picture of surroundingsDo NOT touch any of the items unless it is vital to
the care of your victimEmpty medication bottlesAlcoholWeapons (do not touch unless there is a threat)ChemicalsWho is present (potential witnesses or suspects)SCENE SAFETY!
29
Triage
Mass Casualty SceneHigh number of victimsYou will not be able to handle this situation on
your own.Call for help immediatelyBegin triage process (different than non-
mass casualty incident)
30
Triage
Mass Casualty SceneDone quickly and efficientlyMass casualty triage requires training“Walking wounded”Triage Tag: white, green, yellow, red, black

Control BleedingFirst priority in caring for wounds!It is possible for a person to bleed to death in
a short period of timeArterial bleed: spurts blood each time the
heart beats, can result in heavy blood loss; bright red blood; life threatening – must be controlled quickly
49
First Aid Treatment
Control BleedingVenous bleed: slower, steadier, darker blood;
easier to controlObserve standard precautions
PPEUse thick layers of dressingsAvoid contact with blood as much as possibleWash hands as soon as possible
50
First Aid Treatment
Control BleedingFour methods to control bleeding:
Direct pressureElevationPressure bandagePressure points
51
First Aid Treatment
Control BleedingFour methods to control bleeding:
Direct pressureApply pressure directly to the wound using a gloved
(covered) hand and thick gauze (clean cloth)Apply pressure for 5-10 minutesIf blood soaks through ADD dressing to existing oneDo not disturb any formed clots

First Aid Treatment
ShockA clinical set of signs and symptoms that are
associated with an inadequate supply of blood to body organs, especially the brain and heart
Causes:
Excessive blood lossExcessive pain InfectionHeart attack or strokePoisoningLack of oxygen
Psychological traumaDehydration from burns, vomiting or diarrhea
61
First Aid Treatment
Types of ShockAnaphylactic: allergic reactionCardiogenic: heart attack or cardiac arrestHemorrhagic: blood lossMetabolic: vomiting, diarrhea, electrolyte imbalanceNeurogenic: injury to brain or spinal cordPsychogenic: emotional distressRespiratory: trauma to respiratory systemSeptic: infection that has spread throughout body

(muscle, organs, etc.)White, charred appearanceMay have extreme pain or may little to no pain at all, if
nerves are burnedCan be life-threatening (fluid loss, shock, infection)
76
First Aid Treatment
BurnsTreatment:
Remove source of heatCool the skin areaCover the burn with clean (sterile if available) dressingRelieve painObserve for shock
77
First Aid Treatment
Heat ExposureElevation of body temperature due to extented
exposure to heat source (example: sun, extreme workout, etc.)
Electrolytes can become imbalancedCan be life threateningWater, salt lost through respiration
78
First Aid Treatment
Heat ExposureHeat Cramps:
Muscle pains and spasmsCaused by loss of salt and water through perspirationApply firm pressure to the cramped muscle to provide
reliefHave victim rest in cool areaSips of water or sport drink
79
First Aid Treatment
Heat ExposureHeat Exhaustion:
Overexposure to heatMore severe than heat cramps – affect entire bodyVictim loses water and salt through extreme perspirationElectrolyte imbalanceCall 9-1-1Can be life threateningMove patient to cool areaLoosen, remove excessive clothingCool patient down STAT!
80
First Aid Treatment
Heat ExposureHeat Exhaustion:
If victim is conscious give sips of waterThis condition can lead to heat stroke if not treated
quickly
81
First Aid Treatment
Heat ExposureHeat Stroke:
Prolonged overexposure to high temperaturesTRUE MEDICAL EMERGENCYCall 9-1-1Body retains heat (105 – 106 degrees)Victim is not sweatingDry, hot, red skinRapid pulse (tachycardia)May lose consciousness
82
First Aid Treatment
Heat ExposureHeat Stoke:
COOL VICTIM IMMEDIATELYHigh temperature can lead to seizuresCan go into cardiac arrest if not treated quicklyIf available place victim in cool bath tubPlace ice packs under armpits and in groin area, as well
as rest of the bodyObserve/treat shock
83
First Aid Treatment
Cold ExposureHypothermia:
Sustained body temperature which is lower than normalNormal oral temperature 98.6 degrees Fahrenheit Move victim to warm area as soon as possibleRemove wet clothing (if applicable)WARM GRADUALLY!!!Warming that is done too quickly can cause irregular
heart rhythm and lower temperature of internal organs
84
First Aid Treatment
Cold ExposureFrostbite:
Actual freezing of tissue fluids which damage skin and underlying tissue – can lead to tissue death
Common sites: fingers, toes, ears, nose & cheeksCan actually “burn” tissueImmerse affected body parts in WARM (not hot water)Blisters may form – do not puncture blisters – EVERNeeds medical attention as quickly as possibleObserve/treat for shock
