If a person who has diabetes becomes confused, weak, or unconscious for no apparent reason, he may be suffering from insulin shock (low blood sugar) or diabetic ketoacidosis (high blood sugar).

INSULIN SHOCK (LOW BLOOD SUGAR)

If a person with diabetes takes too much insulin or fails to eat enough food to match his insulin level or his level of exercise, a rapid drop in blood sugar can occur. Symptoms may come on very rapidly and include an altered level of consciousness, ranging from slurred speech, bizarre behaviour, and loss of coordination, to seizures and unconsciousness.

Lightning kills more people every year in the United States than all other natural disasters combined. Carrying or wearing metal objects, such as an ice axe, umbrella, backpack frame, or even a hairpin, increases the chances of being hit.

To calculate the approximate distance in miles from a flash of lightning, count in seconds from the time you see the flash to when you hear the thunder, then divide by five.

Prevention

Excerpt from A Comprehensive Guide to Wilderness and Travel Medicine, by Dr. Eric A. Weiss.

Head trauma and brain injury can result from direct impact or from the shearing forces produced by rapid deceleration. When your head hits a hard object such as a boulder, the impact can fracture the skull, bruise the brain, or cause severe bleeding inside the brain from damaged blood vessels. Shearing forces from sudden deceleration of the brain against the inside of the skull can also tear blood vessels on the surface of the brain, leading to an expanding blood clot and pressure on the brain (intracranial pressure).

Dr. Weiss Advice – Improvisational Technique – Making a Sling with Safety Pins

If the victim is wearing a long-sleeved shirt or jacket, pin the sleeved arm to the chest portion of the garment with two safety pins. If the victim is wearing a short-sleeved shirt, fold the bottom of the shirt up and over the arm to create a pouch. Pin this to the sleeve and chest section of the shirt to immobilize the arm.
