Test 2 Flashcards
Hypothermia
decreased body temp cold illness Combination or cold windy and damp conditions
Hyperthermia
Increased body temp
Hypothermia danger zone
Core temp between77-85 degrees equal death
Hyperthermia danger zone
Core body temp above 104 equal death
Hydration. In cold
Replace fluids as much as if working out in the heat
Dehydration
reduces blood volume equals less fluid to warm tissue
Signs of frostnip
Involves ears nose cheeks fingers and toes
Skin appears firm with cold painless areas
Symptoms of frost nip
May peel or blister within 24-72 hours
How to treat frostnip
Treat with firm pressure no rubbing blowing hot air on the spot
Signs of superfical frostbite symptoms
Superficial skin and subcutaneous tissue
Pale hard cold and waxy With rewarming skin will feel numb then sting then burn may produce painful blisters
Deep frostbite
Serious injury frozen tissue
Medical emergency immediate hospitalization
Rapid rewarming required hot drinks hot pads and blankets
With rewarming skin looks blotchy red swollen and very painful
Can become gangrenous if not treated
Preventing heat illness
Use common sense and caution Fluid replacement Unrestricted replacement Replace fluids every 15 min Fluid replacement equal sweat loss Clear urine Acclimatization Minimum of 10-14 days ID susceptible individuals
Flash to bang theory
Estimation of how far lightning is
Time lighting is sighted count number of seconds until bang is heard divide by 5 miles away the storm is
30 count 6 miles away inherent danger monitor conditions 15 count 3 miles leave field immediatly seek shelter
30 min should pass from last strikebefore returning
Conduction
direct contact with cooler object ex ice towel
Convection
Contact witht cooler air or water mass ex wind
Radiation
Heat generated from metabolism of object
Evaporation
Sweat evaporation from skin surface
Heat stress
Evaporation impaired when humidity reaches 65 percent and stops at 75
Prevention of hypothermia
Proper apparel thin layers that can easily be removed or added
Warm up suits wornduring breaks
Acute injury is
traumatic sudden and onset
chronic injury is
overuse gradual
Sprain
injury to ligament connective tissue behind bones
sprain occurs when
joint is forced beyond normal limits or planes of movement
fractures occur as
a result of stresses and strains placed on bones
signs and symptoms of fractures
deformity tenderness swelling pain on movement crepitus
open fracture
open displacement of bone end through tissue skin increases infection
closed fracture
little or no movement of broken bone
greenstick
incomplete break in bones that havent completely formed common in children
transverse
straight line at right angle to bone direct outside blow to body bending force
spiral
twisting force foot planted and body is suddenly rotated s shaped
comminuted
3 or more fragements of bones hard blow or fall in akward position requries surgery
linear
bone splits along length jumping and landing from height
oblique
axial compression bending and torsion forces on one end while the other end is stabalized
stress fracture
overuse injury weight bearing mostly in foot and leg pain usually a dule ache and worsens doesnt show up on xray til healing
dislocation
1 bone in joint is forced out of its normal and proper alignment must be manually surgically reduced put back in place shoulder elbow fingers
sublixations
comes partially out of alignments then goes back on its own
1st time dislocation treated as
possible fracture
myositis ossificans
repeated bruises or truama to same area calcium deposits form impair movement most often in bicep and quads
muscle cramps
painful involuntary muscle contraction occurs most often in calf ab and hammies
acute onset soreness
accompanies fatigue occurs during and immediatly after exercise
doms
delayed onset muscle soreness appaear about 12 hours later becomes most intense 24-48 hours later symtom free withing 3-4 days ice and stretching
nerve injuries
involve compression or tension
contusion briuse
blow from some external object causes soft tissue to be compressed against bone capillaries return causeing bleeding into tissue
3 grades of severity sprain and strains
mild moderate severe pain swelling instability stiffness rom
mild
normally return to play
moderate
divot felt
severe
total tearing initial pain followed by no pain
hypoesthesia
diminished sense of feeling
hyperesthesia
increased sense of feeling
paresthesia
numbness prickling tingling
neuritis
chronic nerve problem repeated forces
chronic tendinitis
inflammation of tendon pain on movement swelling crepitus warmth
treatment of tendinitis
rest alternative activites
tenosynovitis
inflammation of tendon and synovial sheath surrounding it
bursitis
inflammation of bursa small fluid filled sac acts as lubricant pain in the area restricted movement
bursitis areas
subcromial prepatellar top of knee cap and olecranon tip of elbow most often affected
strain is
tendon injury
sprain is
ligament
dbt and wbt
measured using a psychometer
weight before and after
loss of 3-5 percent of body weight equalts health threat
what is a microorganism
present in human blood and bodily fluid
what is a bloodborne pathogen
microorganism that causes disease
blood borne pathogens
hepatitis b c hiv
higher chance of spreading
hepatits b and c
hepatitis b spread
through sharp objects open wounds body fluids
signs and symptoms hepatitis b
swelling soreness loss of normal liver function sign flu like symptoms fatigue weakness nausea headaches fever jaundice
hbv
can go undetected
prevention of hbv
personal hygiene avoid high risk activites vaccine
which virus has a vaccine
hepatitis b
