Page 4: Seattle/King County EMT-B Class

Factors Affecting Exposure

• Physical condition• Age• Nutrition and

hydration• Environmental

conditions

1

Page 5: Seattle/King County EMT-B Class

Loss of Body Heat

Conduction• Transfer of heat from

body to colder objectConvection• Transfer of heat

through circulating air

Evaporation• Cooling of body

through sweating

Radiation• Loss of body

heat directly into a colder environment

Respirations• Loss of body

heat during breathing

1

Page 6: Seattle/King County EMT-B Class

Rate and amount of heat gain or loss can be modified in three ways:

• Increase or decrease heat production.

• Move to sheltered area where heat loss is increased or decreased.

• Wear insulated clothing.

Loss of Body Heat, continued1

Page 7: Seattle/King County EMT-B Class

Hypothermia

• Lowering of the body temperature below 95°F (35°C)

• Weather does not have to be below freezing for hypothermia to occur.

• Older persons and infants are at higher risk.

• People with other illnesses and injuries are susceptible to hypothermia.

1

Page 8: Seattle/King County EMT-B Class

Mild Hypothermia

Signs and symptoms include:

• Shivering

• Rapid pulse and respirations

• Red, pale, cyanotic skin

1

Page 9: Seattle/King County EMT-B Class

Severe Hypothermia1

Signs and symptoms include:

• Shivering stops.

• Muscular activity decreases.

• Fine muscle activity ceases.

• Eventually, all muscle activity stops.

Page 10: Seattle/King County EMT-B Class

Core Temperature Less Than 80F• Patient may appear dead (or in a

coma).

• Never assume that a cold, pulseless patient is dead.

1

Page 11: Seattle/King County EMT-B Class

• Note weather conditions.

• Identify safety hazards such as icy roads, mud, or wet grass.

(oral, tympanic or axillary)

1

Page 17: Seattle/King County EMT-B Class

Interventions

• Move from cold environment.• Do not allow patient to walk, eat,

use any stimulants, or smoke or chew tobacco.

• Remove wet clothing.• Place dry blankets under and over

patient.• Handle gently.• Do not massage extremities.

1

Page 18: Seattle/King County EMT-B Class

Local Cold InjuriesFrostnip

• Freezing of the skin but not the deeper surface

Immersion (trench) foot• Prolonged exposure to cold water

Frostbite• Freezing of a body part, usually an

extremity

1

Page 19: Seattle/King County EMT-B Class

Emergency Care for Local Cold Injury• Remove the patient

from further exposure to the cold.

• Handle the injured part gently.

• Administer oxygen.• Remove any wet or

restrictive clothing.• Never rub the area.• Do not break blisters.• Transport.

1

Page 20: Seattle/King County EMT-B Class

Warm-Water Bath

• Water temperature should be between 100-112oF.

• Keep body part in water until warm and sensation returns.

• Dress with dry, sterile dressings.

1

Page 21: Seattle/King County EMT-B Class

Cold Exposure and You• EMT-Bs are at risk for hypothermia

when working in a cold environment.• Stay aware of local weather

conditions.• Dress appropriately and be prepared.• Vehicle must be properly equipped

and maintained.• Never allow yourself to become a

casualty!

1

Page 22: Seattle/King County EMT-B Class

Heat Exposure• Normal body temperature is 98.6°F.• Body attempts to maintain normal

temperature despite ambient temperature.

• Body cools itself by sweating (evaporation) and dilation of blood vessels.

• High temperature and humidity decrease effectiveness of cooling mechanisms.

1

Page 23: Seattle/King County EMT-B Class

Heat Cramps• Painful muscle spasms

• Remove the patient from hot environment.

• Rest the cramping muscle.

• Replace fluids by mouth.

• If cramps persist, transport the patient to hospital.

1

Page 24: Seattle/King County EMT-B Class

Heat ExhaustionSigns and symptoms include:

• Dizziness, weakness, or fainting• Onset while working hard or

exercising in hot environment• In older people and young, onset

may occur while at rest in hot, humid, and poorly ventilated areas.

• Cold, clammy skin

1

Page 25: Seattle/King County EMT-B Class

• Dry tongue and thirst

• Patients usually have normal vital signs, but pulse can increase and blood pressure can decrease.

• Normal or slightly elevated body temperature

1 Heat Exhaustion, continued

Page 26: Seattle/King County EMT-B Class

Emergency Medical Care• Remove extra clothing and remove

from hot environment.• Give patient oxygen.• Have patient lie down and elevate

legs.• If patient is alert, give water slowly.• Be prepared to transport.

1

Page 27: Seattle/King County EMT-B Class

Heatstroke

1

Page 40: Seattle/King County EMT-B Class

Spinal Stabilization in Water• Turn the patient supine.

• Restore the airway and begin ventilation.

• Secure a backboard under the patient.

• Remove the patient from the water.

• Cover the patient with a blanket.

1

Page 41: Seattle/King County EMT-B Class

Resuscitation Efforts1

• Hypothermia can protect vital organs from hypoxia.

• Documented case of a survivor of a 66-minute cold water submersion

• Diving reflex may cause heart rate to slow.

Page 42: Seattle/King County EMT-B Class

Diving Problems

Descent problems

• Usually due to the sudden increase in pressure on the body as the person dives

Bottom problems

• Not commonly seen

Ascent problems

movement.• Watch out for vomiting caused by

anxiety.• Do not give anything by mouth.

1

Page 67: Seattle/King County EMT-B Class

Care for Pit Viper Bites, cont'd• If the patient is bitten on the trunk,

lay the patient supine and transport quickly.

• Monitor patient’s vital signs.• Mark the swollen area with a pen.• Care for shock if signs and

symptoms develop.• Bring the snake to hospital if it has

been killed.

1

Page 68: Seattle/King County EMT-B Class

Coral Snakes• Small snake with red, yellow, and black

bands• “Red on yellow will kill a fellow, red on

black, venom will lack.”• Injects venom with teeth, using a

chewing motion that leaves puncture wounds

• Causes paralysis of the nervous system

1

Page 69: Seattle/King County EMT-B Class

Care for Coral Snake Bites• Quiet and reassure the patient.• Flush the area with 1 to 2 quarts

of warm, soapy water. • Do not apply ice.• Splint the extremity. • Check and monitor baseline vital

signs.

1

Page 70: Seattle/King County EMT-B Class

Care for Coral Snake Bites, cont'd• Keep the patient warm and elevate

the lower extremities to help prevent shock.

• Give supplemental oxygen if needed.

• Transport promptly. Give advance notice to hospital of coral snake bite.

• Symptoms include:—Target bull’s-eye pattern—Rash—Painful swelling of the joints

1 Tick Bites, continued

Page 75: Seattle/King County EMT-B Class

Caring for a Tick Bite• Do not attempt to suffocate or burn

tick.• Use fine tweezers to grasp tick by

the body and pull it straight out.• Cover the area with disinfectant

and save the tick for identification.• Provide any necessary supportive

emergency care and transport.

1

Page 76: Seattle/King County EMT-B Class

Injuries from Marine Animals• Coelenterates are responsible for

more envenomations than any other marine life animal

• Have stinging cells called nematocysts

Page 78: Seattle/King County EMT-B Class

2Behavioral Emergencies

Page 79: Seattle/King County EMT-B Class

Myth and Reality

• Everyone has symptoms of mental illness problems at some point.

• Only a small percentage of mental health patients are violent.

• Perfectly healthy people may have symptoms occasionally.

2

Page 80: Seattle/King County EMT-B Class

Defining Behavioral EmergenciesBehavior

• What you can see of a person’s response to the environment and his or her actions

Behavioral crisis• Any reaction to events that interferes with

activities of daily living or that becomes unacceptable to the patient, family, or others

• A pattern, not an isolated incident

2

Page 81: Seattle/King County EMT-B Class

Causes of Behavioral EmergenciesOrganic Brain Syndrome

• Caused by disturbance in brain tissue function

Functional Disorder• Cannot be traced to change in

structure or physiology of the brain

2

Page 82: Seattle/King County EMT-B Class

Organic Brain Syndrome

Causes include:• Sudden illness• Recent trauma• Drug or alcohol intoxication• Diseases of the brain• Low blood glucose• Lack of oxygen• Inadequate blood flow to the brain• Excessive heat or cold

2

Page 83: Seattle/King County EMT-B Class

Safety Guidelines• Be prepared to

spend extra time.• Have a plan of

action.• Identify yourself.• Be calm.• Be direct.• Assess the scene.• Stay with patient.

• Encourage purposeful movement.

• Express interest.• Do not get too

close.• Avoid fighting.• Be honest and

reassuring.• Do not judge.

2

Page 84: Seattle/King County EMT-B Class

• Scene safety is most important. Consider calling appropriate resources if needed.

• Take BSI precautions at all times.

• Avoid tunnel vision.

1. Scene Size-up

• If unconscious, do rapid exam for life threats.

• Assess three major areas as contributors:

• Is patient’s CNS functioning properly?

• Are hallucinogens or other drugs or alcohol a factor?

• Are psychogenic circumstances, symptoms, or illness involved?

Page 87: Seattle/King County EMT-B Class

• Use reflective listening: repeating what the patient has said in question form to help patient expand thoughts.

• Tears, sweating, blushing may be indicators.

• Look at patient’s eyes.• Coping mechanisms are

stressed; perception of reality may be distorted.

Page 90: Seattle/King County EMT-B Class

Interventions

• Be caring and careful.• Intervene only to safely

transport.

2

Page 91: Seattle/King County EMT-B Class

Suicide

• Depression is the single most significant factor that contributes to suicide.

• An attempted suicide is a cry for help.

• Immediate intervention is necessary.

• Suicidal patients will usually exhibit warning signs.

2

Page 92: Seattle/King County EMT-B Class

Critical Warning Signs of Suicide• Does the patient have an air of

tearfulness, sadness, deep despair, or hopelessness?

• Does the patient avoid eye contact, speak slowly, or project a sense of vacancy?

• Does the patient seem unable to talk about the future?

• Is there any suggestion of suicide?• Does the patient have any specific plans

relating to death?

2

Page 93: Seattle/King County EMT-B Class

Risk Factors for Suicide• Are there any unsafe objects in the

patient’s hands or nearby?

• Is the environment unsafe?

• Is there evidence of self-destructive behavior?

• Keep in mind the suicidal patient may be homicidal as well.

2

Page 94: Seattle/King County EMT-B Class

Medicolegal Considerations• Mental incapacity may take many

forms.

• Once a patient has been determined to have an impaired mental capacity, you must decide if care is needed.

• Do not leave the patient alone.

• Obtain help from law enforcement as necessary.

2

Page 95: Seattle/King County EMT-B Class

Consent

• When a patient is not mentally competent, the law assumes that there is implied consent.

• The matter is not always clear-cut with psychiatric emergencies.

• If you are not sure about the situation, request law enforcement assistance.

2

Page 96: Seattle/King County EMT-B Class

Limited Legal Authority

• As an EMT-B, you have limited legal authority to require or force a patient to undergo care.

• Police may put a patient in protective custody to allow you to provide care.

• Know your local laws and protocols.

2

Page 97: Seattle/King County EMT-B Class

Restraints • You cannot restrain a

patient unless it is an emergency.

• Transport a disturbed patient without restraints if possible.

• If you must restrain the patient, use only reasonable force.—Law enforcement

personnel should be involved.

2

Page 98: Seattle/King County EMT-B Class

Potentially Violent PatientsUse a list of risk factors to assess the level of danger:

• Past history• Posture• Scene• Vocal activity• Physical activity

2

Page 99: Seattle/King County EMT-B Class

Other Factors to Consider• Poor impulse control• History of uncontrollable

temper• Low socioeconomic status• Substance abuse• Depression• Functional disorders
