Choking is the
mechanical obstruction of the flow of air from the environment into the lungs.
Choking prevents breathing, and can be partial or complete, with partial
choking allowing some, although inadequate, flow of air into the lungs.
Prolonged or complete choking results in asphyxia which leads to anoxia and is
potentially fatal. Oxygen stored in the blood and lungs keep the victim alive
for several minutes after breathing is stopped completely; but unless the choking
issue has been resolved and life saving measures have been implemented in time,
you could die.
According to the Harvard Medical School Family Health Guide,
a person who is choking
will instinctively grab at the throat. The person also may panic, gasp for
breath, turn blue, or be unconscious. If the person can cough or speak, he or
she is getting air. Nothing should be done. If the person cannot cough or
speak, begin the Heimlich maneuver immediately to dislodge the object blocking
the windpipe.
The Heimlich
maneuver creates an artificial cough by forcing the diaphragm up toward the
lungs. If you are choking and alone, you
can perform the Heimlich maneuver on yourself by giving yourself abdominal
thrusts. Or position yourself over the back of a chair or against a railing or
counter and press forcefully enough into it so that the thrust dislodges the
object. See more info on this topic at this site: http://www.health.harvard.edu/fhg/firstaid/choking.shtml
.
Choking and suffocation is the third leading
cause of home and community death in the United States, according to the
National Safety Council. Foods are responsible for most choking incidents. But
for children, objects such as small toys, coins, nuts or marbles can get caught
in their throats. Choking can cause a simple coughing fit or something more
serious like a complete block in the airway, which can lead to death. Although
choking can occur in people of all ages, children under the age of three are
particularly vulnerable. Older adults also have an increased risk of choking on
food. More details can be found at their site: http://www.nsc.org/safety_home/HomeandRecreationalSafety/Pages/Choking.aspx

To understand choking, you first have to
understand what goes on at the back of your throat hundreds of times per day.
All the food you eat and the air you breathe passes through your throat to get
into your body. Food and liquid go down one pipe — the esophagus— to your
stomach. Air goes down another pipe — the trachea or windpipe — to your lungs.
These two pipes share an opening at the back of your throat, according to
KidsHealth.org.
So if they share an opening, how does the food
know which pipe to go down? Lucky for you, your body has it all under control.
A little flap of cartilage called the epiglottis sits near your trachea, and
every time you swallow, it springs into action. Acting like a little door, it
closes off the entrance to your trachea so that food is sent down your
esophagus into your stomach instead of into your lungs.
But
every once in a while, especially if you are laughing while you are eating, the
epiglottis doesn't close in time. A piece of food can slip down into the
trachea. Most of the time, it's no big deal. Your body makes you cough and
forces it back up. Here are four great ways
to prevent choking:
·
Be extra careful when
eating certain foods that are easy to choke on. They include things like: hot
dogs, nuts, grapes, raw carrots, popcorn, and hard or gooey candy. Check food
labels to make sure the food isn't the kind that can lead to choking.
·
Sit down, take small
bites, and don't talk or laugh with your mouth full! And more than good manners
are at stake. Following that advice will help prevent choking.
·
Look out for the little
guys — and girls. Babies and toddlers love to put things in their mouths, so
help keep them safe by picking up anything off the floor that might be
dangerous to swallow — like deflated balloons, pen caps, coins, beads, and
batteries. Keep toys with small parts out of reach.
·
Learn the Heimlich
maneuver. It's usually taught as part of any basic first-aid course — the kind
that might be held by the Red Cross, the YMCA, the American Heart Association,
schools, or hospitals in your community. Who knows? You could be a lifesaver
someday!
The
body needs oxygen to stay alive. When oxygen can't reach the lungs and the
brain, a person can become unconscious, sustain brain damage, and even die
within minutes. That's what makes choking such a serious emergency. More info can be found at this website: http://kidshealth.org/kid/watch/er/choking.html#
.
Choking can
be prevented, according to HealthyChildren.org. Food accounts for over 50% of
choking episodes. Be alert for small objects that can cause choking. Check
under furniture and between cushions for small items that children could find and
put in their mouths. Toys are designed to be used by children within a certain
age range. Age guidelines take into account the safety of a toy based on any
possible choking hazard. Don’t let young children play with toys designed for
older children. Latex balloons are also a choking hazard. If a child bites a
balloon and takes a breath, he could suck it into his airway. More details can be found here:
http://www.healthychildren.org/English/health-issues/injuries-emergencies/pages/Choking-Prevention.aspx
If you
encounter a conscious, choking individual that is coughing, encourage continued
coughing. The Red Cross has a great overview of how to
help someone who is choking: http://www.redcross.org/flash/brr/English-html/conscious-choking.asp
.
If an adult is choking, you may,
according to eMedicineHealth.com, observe the following behaviors:
- Coughing
or gagging
- Hand
signals and panic (sometimes pointing to the throat)
- Sudden
inability to talk
- Clutching
the throat: The natural response to choking is to grab the throat with one
or both hands. This is the universal choking sign and a way of telling
people around you that you are choking.
- Wheezing
- Passing
out
- Turning
blue: Cyanosis, a blue coloring to the skin, can be seen earliest around
the face, lips, and fingernail beds. You may see this, but other critical
choking signs would appear first.
If an infant is choking, more
attention must be paid to an infant's behavior. They cannot be taught the
universal choking sign.
- Difficulty
breathing
- Weak
cry, weak cough, or both
Choking is a
true medical emergency that requires fast, appropriate action by anyone
available. Emergency medical teams may not arrive in time to save a choking
person's life.

Choking
can be dangerous, and should not be taken lightly by anyone. Children, senior
citizens, and those with certain physical handicaps should always be on your
watch list to keep safe from the dangers from choking. And, make sure you know
how to call for help, and learn how to use the Heimlich manuever.
Until
next time.
