In
this article, you will be exposed to, how first aid care should be rendered in
life-threatening situations. You will be taught how to clear an obstructed
airway and restore breathing if possible. Above all, you should be able to
use first aid care on all these life-threatening situations.
By
the end of the post, you should be able to mention life-threatening conditions which
may require emergency treatment, explain how an obstructed airway should be
cleared and describe how breathing can be restored in a casualty that is not
breathing.
First Aid Care for Life-Threatening Emergencies
Life-threatening
conditions which require emergency treatment are experienced when:
1.
There is an obstruction in the airway or air passages.
2.
Breathing has stopped.
3.
There is severe bleeding.
4.
There is a case of poisoning.
Each
of these conditions may lead to serious damage to the vital organs (e.g. brain,
heart) or death within a few minutes if proper first aid care is not given
immediately.
Therefore,
each requires the provision of urgent care. Since hardly anyone is prepared for
them, the best thing to do is to familiarize oneself with the measures to take
when confronted with any of them.
Clearing Obstructed Airway
Blocked or obstructed airway leads to respiratory failure (Asphyxia).
In an unconscious
casualty, the epiglottis which acts as the protective mechanism by preventing
any foreign matter such as food or fluid from entering the windpipe (trachea)
fails to function.
This
provides a dangerous opportunity for saliva, blood, or regurgitated stomach
contents (vomit) to be entering the windpipe thereby blocking the airway.
Besides, there is the possibility of constriction around the neck or the tongue
falling to the back of the throat to block the airway if the victim is left
lying on his or her back.
When
any of these obstructions take place, noisy breathing is experienced, if breathing
has not stopped entirely. In order to open the airway, the casualty's chin is
lifted forwards with the index and middle fingers of one hand while pressing,
the forehead backwards with the heel of the other hand.
In
this open airway position, the airway should be cleared by turning the victims
head to one side, keeping it well back. Then if the foreign body is visible in
the mouth or throat the first two fingers are used to remove or hook out the
obstruction.
Moreover,
fingers can be used to sweep around inside the mouth to remove obstructions
without wasting time searching for hidden ones. This may cause vomiting with
the removal of the foreign body. Trained ambulance personnel may provide
mechanical suckers or suction tubes for this purpose. Where the above methods
fail to remove the obstruction from the throat the casualty should lean forward
and be struck firmly on the back between the shoulders.
If
all these methods fail, the only hope is a tracheostomy performed by a doctor
or in desperate circumstances by a highly-skilled first aider or trained nurse.
Tracheostomy involves cutting into the middle of the trachea or windpipe below
the larynx (Adam's apple) and inserting a small tube.
Restoring Breathing
In
order to determine whether or not a casualty is breathing, the first aider
should place his ear above the casualty's mouth and look along the chest and
abdomen. If the casualty is breathing, the breaths will be heard and felt and
the movement along the chest and abdomen will be observed.
In
order to discover whether or not the heart has stopped beating, the pulse
should be checked at the neck by placing the fingertips gently on the voice box
and sliding them down into the hollow between the adjoining muscles. This is
referred to as carotid pulse.
A
situation where pulse is present and another situation where there is no pulse
will require different approaches. In the first case, breathing is restored by
giving the victim immediate Artificial Respiration.
In
the case where the heart has stopped beating, i.e. no pulse, a combination of
artificial ventilation (respiration) and chest compression is carried out. This
combined approach is known as Cardiopulmonary Resuscitation (CPR).
Performing Cardiopulmonary
Resuscitation (CPR) on a Victim
However, certain swift preliminary investigations or activities must be completed before artificial respiration is administered.
The first major requirement is that the
cause of the respiratory failure should be determined and removed or rectified.
Breathing
failure may result from such conditions as:
a.
Blocked airway.
b.
Electric shock.
c.
Breathing air that lacks sufficient oxygen.
d.
Inhalation of large quantities of carbon monoxide.
Specifically,
these conditions should be rectified by one or a combination of: opening
airway, supplying adequate air (or oxygen), or removing the casualty from the
cause, or the cause from the casualty.
In
conclusion, having gone through this unit on sports emergencies and how to
carry out first aid treatment on these emergencies you should be able to clear
an obstructed airway and also help to restore breathing in such emergencies.
This article have exposed you to life-threatening emergencies and how you can be
handled. You also learnt how blocked airways can be cleared and restoring
breathing to the casualty where necessary.
