Enviromental Emergenices + CBRNE Flashcards
What is the homeostasis in temp in the body
36.9
What makes freezing worse
Freezing and thawing then refreezing
Ice crystals form damaging
Blood vessels
Forstbite
Extremity will look white and waxy
When rewarded will turn purple or burgundy and swelling will start
Can turn black over time
Nelcrosis
Turns black
Treat forstbite
Treat hypo first
Don reheat in feild
Bulky splinting
Hospital will warm with 40.c water and liberal opioids
What is hypothermia
Core temp less than 35.c
3 causes of hypo
Cold water
Cold weather
Urban hypo ( pt indoootb, but thermal auto regulation is decreased )
Who at higher risk
Burns
Alcohol
Cns deoressants
Shock
Diabetes
HT 1 treatment
Remove wet clothes
Provide warm environment
Warm sweet drinks
Blanket
Encourage active movement
H2-h3 treatment
Handle gently
Keep horizontal
Active rewarding in trunk only
Mandoratory Olmc
Considering transport to encourage / CPB facilities
H4 treatment
Remove from cold environment
Rewarm core
Trans to Ecmo/ CPB
Maintain horizontal
CPR and defibrillation ( max 3 shocks until warm ) ( if Rosc occurs maintain hypo in head only
HT 5 treatment
Don’t attempt resuscitation
Warm the pt up ?
Slowly do the heart can keep up
Get your pt _ has it the best way to keep them warm
Shivering
Conduction
Losing body heat to near by objects by touching them
Covection
Loading heat to air
Radiation
Lost of body heat to object by not touching it
Evaporation
Loss by perspiration
Travis of death
Hypothermia low body temp
Acidosis Latin acid in blood
Coagulapathy blood cloying promblem
Heat cramps
Caused by excessive loss of Salt or water
Pain in abdomen or lower extremities due to hydration over acceleration in a hot environment
Muscle twitching
Diaphoresis
Nv
Spams
Treatment for heat cramps
Remove to cold environment
Iv
Oxygen
Give electrolytes only to non-throwing up patient
Heat exhaustion
More severe cramps with more fluid loss
A form of absolute hypovolaemic shock
Weak, pale skin
Nausea, vomitiw
Hypotension
Treatment for heat exhaustion
Remove to cold envro
Iv
Nothing Orly
Heat stroke
Complete failure of bodies temp to regulation can be chronic or acute
Classic heat stroke
Dry skin
Likely to happen in very old and very impatient
May take hours or days
Hi mortality rate
External heat stroke
Sweaty skin
Acute rise in temperature due to them bodies cooling becomes in effective very common in young fit people/athletes and firefighters
Signs and symptoms of heat stroke
Kussmaul
Lack of sweating
Treatment for heat stroke
Remove all clothing
Cool environment
Ice packs to groin and axillary armpits, but no ice on dark skin
Do all of this while assessing the primary and managing ABC’s
What drug causes see you the ability not to sweat
Anti-histamines
Heat cramps are
Electrolyte imbalances
Heat exhaustion is
Absolute hypovoemia
Heat stroke is
Hyperthermia failure of comp mechanisms
Kids are at higher risk for
Febrile seizures because they have problems regulating the temperature
All drownings in Alberta are considered
Cold or freshwater, drowning
Drowning
It’s due to a vaccination and does not have to be water
Near drowning
The process of August drowning, but being interrupt reversed prior to death
What percent of John involve alcohol
75%
Dry drowning
10 to 20% of the time
Laryngeal spasm stop water
Best chance of rehabilitation
Wet drowning
80-90% of the time
panic and lungs, but with water
Secondary drowning
Respiratory pulmonary oedema liquid in the lungs occurs minutes to days after the event
CBRNE
Stands for chemical biological radioactive nuclear an explosive
Triage rule
Treat black as read
Class A to class B
Clase is the least protection with just a filter mask to level d is full scoop up with a fully enclosed suit
Biological
A bacterium virus or partisan, parasite or fungus example anthrax
Signs and symptoms are nausea bottle thing, respiratory distress, blistering, skin, irritation, bronco spasms, and Sluggo
Radioloical
