HYPOTHERMIA FIRST AID
When
exposed to cold temperatures, especially with a high wind chill factor and high
humidity, or to a cool, damp environment for prolonged periods, your body's
control mechanisms may fail to keep your body temperature normal. When more
heat is lost than your body can generate, hypothermia, defined as an internal
body temperature less than 95 F (35 C), can result.
Wet
or inadequate clothing, falling into cold water and even not covering your head
during cold weather can increase your chances of hypothermia.
Signs
and symptoms of hypothermia include:
·
Shivering
·
Slurred
speech
·
Abnormally
slow breathing
·
Cold,
pale skin
·
Loss
of coordination
·
Fatigue,
lethargy or apathy
·
Confusion
or memory loss
·
Bright
red, cold skin (infants)
Signs
and symptoms usually develop slowly. People with hypothermia typically
experience gradual loss of mental acuity and physical ability, so they may be
unaware that they need emergency medical treatment.
Look
for “Umblings”, fumbling, mumbling, stumbling, grumbling. All could be signs of
a person becoming hypothermic.
Older
adults, infants, young children and people who are very lean are at particular
risk. Other people at higher risk of hypothermia include those whose judgment
may be impaired by mental illness or Alzheimer's disease and people who are
intoxicated, homeless or caught in cold weather because their vehicles have
broken down. Other conditions that may predispose people to hypothermia are
malnutrition, cardiovascular disease and an underactive thyroid (hypothyroidism).
To
care for someone with hypothermia:
·
Call 911 or emergency medical assistance. While waiting for
help to arrive, monitor the person's breathing. If breathing stops or seems
dangerously slow or shallow, begin cardiopulmonary resuscitation (CPR)
immediately.
·
Move the person out of the cold. If going indoors
isn't possible, protect the person from the wind, cover the head, and insulate
the individual from the cold ground.
·
Remove wet clothing. Replace wet things with a warm,
dry covering.
·
Don't apply direct heat. Don't use hot
water, a heating pad or a heating lamp to warm the person. Instead, apply warm
compresses to the center of the body — head, neck, chest and groin. Don't
attempt to warm the arms and legs. Heat applied to the arms and legs forces
cold blood back toward the heart, lungs and brain, causing the core body
temperature to drop. This can be fatal.
·
Don't give the person alcohol. Offer warm
nonalcoholic drinks, unless the person is vomiting.
Don't massage or
rub the person.
Handle people with hypothermia gently because their skin may be frostbitten,
and rubbing frostbitten tissue can cause severe damage.
