lecture 12: heat regulation Flashcards
factors that effect exposure to thermoregulatory injuries
physcial condition
age
nutrition and hydration
environment
how does the body lose heat (5 ways)
radiation (body heaet emitted to envinroment)
convection (air close to skin moves away taking hear with it)
conduction (dircet contact witth another surface
evaporation (sweat)
respiration
whatt are causes of burns
chemicals
heat
electricty
radiation
explain 1st degree burn
superfical (top later)
ex: sunburn
explain 2nd degee burn
partical thickness
blisters
explain 3rd degree burns
full thcickess
black or whitte charred tissue
true or false: use ointment or petrolum products on burn
false
what is the treatmetn for a burn
flush with cold water for 15 minutes
cover with loes dyy sterol dressing
what are the 4 exercttional heat illenesses
heat syncpe
heat cramps
heat exhaustion
heat stroke
what is heat sympcome
orthostatic dizziness
dehydration, low BP, venous pooling)
SS of heat symcope
fainting dizzy tunnel video pale/sweater low HR
treament of heaet syncome
shade vitals cool skil elevate hydrate
true or false: heat cramps are sign that body is starting to overheat
true
what are heat cramps
painful msucle spasms after vig exrcersie
what are contributing factors to hear cramps
dehydration
electrolyte imbalcace
fatigue
SS of heat cramps
visible cramp lpain thirst sweat fatigue
what is the core temp for heat cramps
aslightly elevated core (37)
treamtent of exercise induced muscle cramps
rest shade/cool slight electroly bev passing stretching ice/massage
when can an atnelete RTP with heat cramps
when cramps stop and no other sisns
what is core temp for exertional heat exhaustion
37-39
SS of heat exhaustion
fatigue profuse sweat faint weakness vomit nausea low BP
treament of heat exhaustion
REST
Remove excess clothing/equipment
Cool or shady place (Fans, ice towels, cold pack to armpits and chest)
Monitor vital signs
Fluid replacement (slowly sip a cool electrolyte-replacement beverage)
Supine position with legs elevated
Cool athlete until rectal temperature 38.3°C
**If no improvement within 30 minutes, activate ERP
Call EMS/9-1-1 if the person is vomiting, has an altered level of responsiveness, or is unable to
drink fluids
Treatment of Heat Exhaustion
36
which is the least common but most severe
heat stroke
what is body temp for heat stroke
40.5
what is first sign of EHS
CNS disfunction(Agression. collapse)
SS of heat storke
high core temp flushed or pale skin hypotension third condion
tx heat storke
Remove excessive clothing/equipment
Goal is to lower core temperature to less than 38.9 C (102F)
Quickly immersed in a pool or tub of cold water (2 C - 14 C)
Up to neck is most effective
Stir for maximum cooling
treatment of heat related injuries
Heat (Muscle) Cramps
Stop exercise, fluids, massage and stretch
Heat Exhaustion
Stop, cool the body, re-hydrate
Heat Stroke
Cool the body, medical attention, cold fluids, immerse in cool water
