|
in electric trauma, does voltage or amperage kill

amperage!
amp = voltage/resistance this is equation for flow of energy -- low resistance via water coincides with higher energy flow coincides with death by vfib et al |

What's the difference between frostbite and frostnip and chillblain

Frostnip refers to cold-induced, localized paresthesia that resolves with rewarming with no permanent tissue damage. Pernio (chilblain) is characterized by localized inflammatory lesions, resulting from acute or repetitive exposure to damp cold temperatures above freezing. Frostbite is a severe, localized cold-induced injury.
