What are heat emergencies?

Heat related emergencies are a health crisis caused by exposure to hot weather and sunHeat Stress

Heat Exhaustion

Heat StrokeSlide3

Who is at Risk?

Young ChildrenPeople aged 65 and older

Outdoor laborers

AthletesSlide4

How does our body work to cool itself?

Conduction- Heat loss through direct contact with a cool object

Convection- the dissipation of heat when cool air passes over exposed skin

Radiation-the release of heat from the body into the environment

Evaporation- through perspirationSlide5

The Heat Index

Air Temperature + Relative Humidity

The human body normally cools itself by

perspiring and then evaporating

Relative Humidity reduces the evaporation rate

High humidity reduces the body’s ability to get rid of excess heat Slide6
Slide7

Factors Leading to heat Related Emergencies

High temperatures and high humidity

Direct sun or heat

Limited air movement

Physical exertion

Poor physical condition

Protective clothing

Some medications-

beta blockers, calcium channel blockers, diuretics, laxatives

Inadequate tolerance for increased heatSlide8

Heat Stress

First stage of a Heat EmergencyMuscle pain and tightness

More likely to happen to the elderly, small children, overweight individuals, and those drinking alcoholSlide9

Heat Exhaustion

Muscle Cramps Dizziness and Fatigue

Headache

Irritability

Nausea or Vomiting

Flushed Skin that is Hot to the Touch (up to 104° F)

Heavy Sweating

Visual disturbances

Rapid pulseSlide10

Heat Stroke

May have all the signs of heat exhaustion plus:Dry, hot skin usually without sweating

Confusion

Rapid shallow breathing

Rapid weak pulse

Seizures

Loss of consciousness

Body temperatures that can reach 105° FSlide11

Treating Heat Related Emergencies- Heat Cramps

At first sign of a heat related emergency:Move the person to a cooler area and out of direct sunlight

Gently message the cramping muscles

Offer water or a sports drink every 15 minutes- drink slowly!Slide12

Treating Heat Related Emergencies- Heat Exhaustion

Move the person to a cooler area and out of direct sunlightLoosen clothing and/or remove out layers

Fan the individual’s skin

Offer cool water or a sports drink every 15 minutes

If symptoms do not improve or get worse call 911 or go to the Emergency RoomSlide13

Treating Heat Related Emergencies- Heat Stroke

Heat stroke is a life threatening emergency, call 911Move the person to a cooler area and out of direct sunlight

Loosen clothing and/or remove out

layers

Fan the individual’s skin

Apply cool, wet towels to the face, neck, chest, and limbs

Apply ice pack to neck, armpits and groin

Offer cool water or sports drink every 15 minutesSlide14

Preventing Heat Related Emergencies

Drink Plenty of Fluids- avoid alcohol and caffeinated drinks

Wear appropriate clothes- light colored, light weight, wide brim hats

Stay Indoors During Mid-Day- between 10am-6pm

Watch the Heat Index

Seek Air-Conditioned Environments

Know the Warning Signs of Heat-Related EmergenciesSlide15

Important Points to remember!

ALWAYS call 911 if the heat emergency is causing vomiting, seizures, or loss of consciousnessDo not give the individual anything to drink if they are vomiting or unconscious

Never give the individual a drink containing caffeine or alcoholSlide16

Potential Complications from heat emergencies

Vital organ damage, especially brain and kidneyDeath- 40% of heat related deaths come from Texas, Arizona, and California

Heat stroke causes about

700 deaths per yearSlide17
