1

J-waves/Osborn waves are seen in:

hypothermia

2

characteristic EKG finding of hypothermia

J-waves/Osborn waves

3

In treating hypothermia, at what temperature should you initiate resuscitation meds and defibrillation attempts?

T > 30C

4

What are treatments for high altitude pulmonary edema? (4)

descent acetazolamide dexamethasone nifedipine

5

pressor to use in heat stroke

dobutamine - supports BP and HR while keeping vessels dilated for heat dissipation

6

when should you consider active rewarming measures

cardiovascular instability, T < 32ºC, or inadequate response to passive re-warming methods

7

order of tissues with resistance to electricity

Bone > fat > tendon > skin > muscle > nerve.

8

how do you grade frostbite injuries?

 1st degree- numbness and erythema with no tissue loss
2nd - superficial blistering, with clear to milky fluid, surrounded by edema and erythema
3rd - deeper blisters with blood containing fluid (leave blisters alone)
4th - affects muscle and bone.

9

mild vs moderate vs severe hypothermia
(definitions and treatment)

mild 32-35: active external warming
moderate 28-32: +active core (bladder, gastric lavage)
severe < 28: ECMO, pleural lavage

10
