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.
Teeth sensitivity or when your teeth hurt means that you have dentin hypersensitivity. This is due to cold factors affecting your teeth: eating of cold food, drinking of cold liquid beverages and cold air conditioner or cold air.If this condition gets to be prolonged or if the pain is truly excruciating, then, this is a symptom of unhealthy teeth and the nerve that goes with it.The condition starts when the gums recede or ebb. The gums protect the roots of the teeth like a blanket covering a child from the cold.hese roots have tubules or the tubes that are connected to the nerves of the tooth. Tooth ache or pain is being activated when there is pressure or cold stimuli. This happens because the roots are open and bare. If it was not, then, there would be no pain since the root is being enveloped by the gums.
