AEDs Arrive. Around 1980, the AED (automated external defibrillator) debuted. The 'automated' part is what is really exciting. Now people with only minimal training can successfully revive VF victims in the field, even before Emergency Medical Services personnel arrive.
Sensitivity has many shades of meaning but most relate to your response to your environment â either physical or emotional. Sensitivity to cold means youâre quick to notice the slightest chill â in the air or in another personâs actions. A sensitivity to pollen means youâre sneezing any time itâs in the air â you just always seem to react to it. Itâs the same with emotions â sensitivity means you pick up on the feelings of others.
Hypothermia and Frostbite Hypothermia When exposed to cold temperatures, your body begins to lose heat faster that it can be produced. Prolonged exposure to cold will eventually use up your bodyâs stored energy. The result is hypothermia, or abnormally low body temperature.
