Counting that problems may occur with heart beats and
breathing, people around the casualty may think he is
dead. According t that first aids must e provided as

2. Ways
To
Save A
Casualty’s
Life |
A) Fre
Eing The
Person
In Shock
From The
Connection
Freeing the person in sock from the connection must be
done as son as possible and that should be done by
turning the power off from the direct plug or from the
general power line of the area where the accident
happened. The person helping the casualty must never
touch him with bare hands or he will be electrocuted.
Paying attention to the place of the casualty is
important because he might fell down from a high place
and in situations where cutting the power is hard the
following should be done:
-
If the voltage is 1000 Volts or less:
To disconnect the casualty from the objects that
have electrical current, dry objects like wood,
robes and clothes can be used but never wet or metal
objects because they are good connectors of
electricity. After the rescuer wears thick isolation
gloves, or covers is hands with a dry thick piece of
cloth, he should pull the casualty away from the
power supply and he should not use more than one
hand carefully and in the case of not being able to
get the casualty’s fingers of the wire, a piece of
wood should be placed under the casualty’s foot to
isolate him from the ground.
-
If the voltage is 1000 Volts or more:
Isolation equipments that have the capacity of
working with such voltage should be used like
wearing gloves and rubber shoes and using a piece of
wood to get the casualty away from the high pressure
cables. Also wiring the high pressure wires by
connecting the ground point or the high voltage
tower and the area of connection where the accident
is; in that case, the casualty will fell down so
precautions must be taken to avoid more accidents.
Great attention must be given to the grounding of
the area of the accident because a high charge will
remain in that area.

B) First Aids
After disconnecting the current, a doctor or a
specialist must be present with following the next
steps.
-
The
casualty must be laid down on his back and it is
recommended to be on a straight dry surface.
-
The
casualty's mouth must be checked and all the objects
that prevent breathing weather it was solid or
liquid must be removed; the head's position must be
corrected to make breathing possible without
anything in its way.
-
Making
sure that the casualty is breathing by watching his
chest moving up and down.
-
Making
sure that the casualty's pulse is working and that
should be done by checking his rest or neck to find
out if the heart is still beating.
-
Watching
the pupil, because if it gets wide it means that
there is no enough blood going to the brain.
|
|
If the patient does not breathe or his heart is not
beating, then the rescuer must do the jobs of the lungs
and heart by giving the patient the kiss of life and
massaging the chest to help the heart as follows:
-
put the
patient on his back and remove all objects from his
mouth.
-
Place
one of the hands under the patient's neck and make
the neck on a concave up position and put the other
hand on the patient's forehead to open his mouth.

-
Take a deep breath and place your lips on the
patient's lips and close his nose with your pointer
and thump and blow in his mouth until you see his
chest going up.

-
Move your mouth away
and watch his chest going down and do that once
every four seconds.

-
If the patient's chest
does not move, that means that there is something in
his mouth that must be removed.
-
This operation should
be done to the adult once every 4-5 seconds and to
children every 3 seconds until the patient starts
breathing on his own.
-
Place a blanket under
the patient and do not let him get up for an hour so
that his body rests and gets warm until a doctor or
emergency gets there.

Exterior
massaging for the heart: |
-
Using
the operation of exterior massaging to the heart
with the kiss of life with attention that the two
operations do not interfere with each other. The
breathing operation must be done quickly and the
massaging operation must be done to make sure that
the blood gets to the brain, kidney's and liver if
one person is doing both jobs. If two people are
doing them, then they should take turns in doing
their jobs to guarantee the safety of the patient.
-
To
massage the patient, he must be on his back on a
solid dry surface.
-
Feel the
patient's chest until you reach the bottom of the
rip-cage and put one of your left hand's fingers on
that end and move that right arm's wrest (not the
arm) over the bottom third if the chest and put the
left hand over the right one, then get your fingers
away from the patient.

-
Push
down with a speed that is no less than one time
every second with both hands with enough power to
push the chest down for about 3-5 cm and that should
be done with straight arms to use your body's weight
to make the operation easier to do for a longer
time, then remove your body's weight and leave your
hands on the chest and repeat these steps regularly.
Every time you do that, it is like doing the heart's
job.
-
The
massaging operation must be done every five times of
the breathing operation.
If one person is doing the operation then the
following steps must be followed:
Give the patient the kiss of life twice or three
times then do the exterior heart massaging 12 times.
If two rescuers are present then each of them should
do one of the jobs and that should be done until the
patient gains full conscious. This operation must
also be done on the way to a clinic or any emergency
place.
