25
treatment for heat exhaustion
* remove patient from the hot environment * loosen any tight clothing * apply water and fan/AC * cold pack in the groin and axilia * oxygen if shortness of breath is present * transport
26
signs and symptoms of heat stroke
* confusion, change of behavior, seizures * hot, dry, flushed skin could still be moist * sweating has stopped * body has lost its ability to compensate
27
signs and symptoms of extertional heat stroke
skin may still be moist
28
treatment for heat stroke
* move patient out of hot environment * oxygen if shortness of breath is present * remove the patient's clothing * apply water and fan/AC * apply cold packs to the patient's neck, armpits, and groin trasport
29
drowning
death as a resut of suffocation after submersion in water
30
near-drowning
survival, at least temporarily, after suffocation in water
31
complications of drowning
* spinal injuries * hypothermia * diver's reflux
32
complications of secondary drowning
* pulmonoary edema secondary to aspiration of fresh or saltwater
33
complications of shallow water drowning
* loss of stimulus to breathe
34
signs and symptoms of spinal injuries
* submersion has resulted from a diving mishap or long fall * patient is unconscious * patient complains of weakness, paralysis, or numbness * suspect possibility of spinal injury
35
treatment for near-drowning
* rescue and remove from water * spinal motion restriction * be prepared to suction * high flow oxygen via mask or BVM * CPR is necessary * remove wet clothing to prevent/treat for hypothermia * transport
36
descent problems
* usually due to the suddent increase in pressure on the body as the person dives * sinuses, ear drums pop
37
bottom problems
not commonly seen
38
ascent problems
* air embolism and decompression sickness
39
signs and symptoms of air embolism
* pressure decreases, air expands while in alveoli, blood stream * rapid onset when at surface * air enters pleural space, mediastinum, and bloodstream * dizziness, nausea, vomiting * dysphasia * difficulty with vision * dyspnea * muscle/joint pain * paralysis/ and or coma * irregular pulse or cardiac arrest
40
signs and symptoms of decompression sickness (The Bends)
* occurs from too rapid ascent * occurs when bubles of nitrogen obstruct blood vessels * symptoms may develop while driving/flying * gradual onset * joint pain * abdominal pain * general fatigue * ataxia, dysarthria * vertigo * nausea/vomiting
41
treatment for diving emergencies
1. remove patient from water 2. administer high flow oxygen 3. left lateral or supine 4. notify 911 for prompt transport to hyperbaric chamber for recompression
42
acute mointain sickness
physical distress from difficulty adjusting to lower oxygen pressure at high altitude.
43
high altitude pulmonary edema (HAPE)
fluid into the lungs
44
high altitude cerebral edema (HACE)
fluid into the brain
45
lightning strike
* electrical problems with the heart/ nervous system injury * reverse triage
46
radiation exposure
* cel phones * microwave ovens * ultraviolet (UV) light from the sun
47
types of bites
* bee stings * spider bites * snake bites * scorpion stings * dogs and humans * marine animals
48
treatment for bees, hornets, and wasps
* remove the stinger with a dull edge * monitor for anaphylaxis
49
treatment for spider bites
* ensure scene safety * provide BLS transport * administer oxygen if shortness of breath
50
pit vipers
* venom stored in sacs behind eyes * injected to victim by fangs * not fatal * hemolytic; tissue damage
51
coral snakes
* injects venom with teeth, using chewing motion and eaving puncture wounds * venom causes paralysis of the nervous system
52
treatment for snake bites
treat with O2
53
scorpion stings
* neurotoxic venom * stinger is found in the tail
54
treatment for scorpion stings
* provide BLS care/ support and transport
55
tick bites
* infects organism through saliva
56
treatment for tick bites
use fine tweezers, grasp the tick by the body and pu it straight out of the skin
57
signs and symptoms of rocky mountain spotted fever
* nausea * vomiting * headache * weakness * paralysis
58
signs and symptoms of lyme disease
* bullseye rash * swelling of the joints * confused with rheumatoid arthritis
59
treatment for lyme disease
antibiotics
60
treatment for dog bites
* apply dry sterie dressings over wound and transport promply * rabies vaccine injections
61
treatment for human bites
* apply dry sterile dressing * provide transport to the hospital for surgical cleansing and antibiotic therapy
62
signs and symptoms of stinging marine animals
* headache * dizziness * muscle cramps * fainting
63
treatment for marine stings
* limit further discharge * apply rubbing alcohol and warm water * monitor for anaphylaxis * provide transport to hospital
