|
Body temperature is regulated by thermoregulatory center in the posterior (blank) of the brain.
|
hypothalamus
|
|
|
Temperatures above (blank degrees F) is considered extreme elevated and can cause multi-system damage and physiolobical collapse.
|
105.8
|
|
|
Body tempseratures below (blank F) cause decreased LOC and poor judgement, cessation of shivering and uncoordination.
|
90 degrees F
|
|
|
Body temperatures below (blank degrees F) usually result in unconsciousness and possible vfib.
|
82.4 degrees F
|
|
|
The body produces heat through normal chemical reactions known as (blank).`
|
metabolism
|
|
|
The body loses heat through (blank, blank, blank, and blank).
|
Radiation, conduction, convection and evaporation
|
|
|
To rid the body of excess heat, the body (a. vasodilates, or b. vasoconstricts) and sweats, decreases metabolism, decreases hormone secretion (epinephrine etc) and increases body surface area by position to maximize evaporation and convection.
|
a. vasodilates
|
|
|
Alert, hot and sweaty skin, localized muscle cramps in the extremities, occasionally abd cramping with normal vital signs, tachycardia and normal body temperature and cool or slightly warm skin are S/S of (blank).
|
heat cramps
|
|
|
Field treatment for heat cramps is:
|
remove pt. from hot environment and replace the sodium and water via IV NaCl.
|
|
|
Minor abberations in mental status such as irritability, confusion, poor judgment, headache or light-headedness, pale skin, excessive sweating with slight or no temperature increase (less than 103 degrees F) are s/s of (blank).
|
heat exhaustion
|
|
|
S/S: Dizziness, headache, bizarre or unusual behavior, seizures, coma. Vital signs include a normal or decreased BP, tachycardia, bounding pulse, tachypnea. Temp is above 105.8, skin is hot, red and dry, but could still be wet from previous perspiring.
|
Heat Stroke
|
|
|
Field treatment of heat stroke:
|
Move patient out of the hot environment, remove clothing, cool with moving air and/or cold packs, high-flow oxygen, intubation, valium for seizures.
|
|
|
Define the parameters and s/s of the three types of hypothermia.
|
Mild: core temp 93.2 to 96.8 Shivering stops at 90 degrees F., impaired judgement, decreased coordination
Moderate: Core Temp 86 degrees to 93.2 with respiratory depression, myocardial irritability, a-fib, bradyarrhythmias, pvd's cerebral blood flow redused. Severe: core temp less than 86 degrees F, fixed/dilated pupils, unconscious, V-fib, cardiopulmonary arrest, systemic acidosis. |
|
|
Treatment for hypothermia:
|
Mild: passive re-warming, active external re-warming.
Moderate: passive re-warming, active external re-warming of truncal areas only. Severe: active re-warming, warm IV fluids, warm/humid O2. CPR: Give 1 shock, resume CPR after shock, manage airway, ventilate with warm/humid oxygen, establish IV infuse warm fluids. |
|
|
Things to remember to treat for drowning and near drowning patients:
|
c-spine precautions, remove wet clothes and warm patient, O2, ventilate, IV/NaCl, ECG, handle gently to avoid causing v-fib for hypothermic pts., CPR and meds as needed.
|
|
|
Salt water drownings tend to cause (blank) because it is a hypertonic solution.
|
pulmonary edema
|
|
|
Fresh water is (blank) causing the water to move out of the lungs and into the body's circulation. This results in...
|
hemolysis (RBC rupture), electrolyet abnormalities, and washes out and dilutes the surfactant causing atelectasis and hypoxia in the aveoli.
|
|
|
S/S of decompression illness (the bends).
|
Hx of scuba diving within the past 12 to 36 hours.
Shortness of breath. Itch, rash, joint pain, paralysis, fatigue, vertigo, numbness, paralysis seizures, coma. |
|
|
Field treatment for decompression illness.
|
ABC' sO2, IV, ECG, rapid txp to facility with hyperbaric chamgber.
Avoid txp in high/altitude aircraft. |
