Shock is a
life-threatening condition, and should not be confused with the flood
of adrenaline that accompanies dangerous or fearful situations. This
reaction to danger or fear is called the ‘fight-or-flight’ reaction,
and is often confused with, and referred to as, ‘shock’. This
condition should be treated as top priority, second only to attending
to safety, an obstructed airway, absence of breathing, cardiac arrest
or severe life threatening bleeding.
Causes of shock
Loss of blood - Shock is most often caused due to loss of blood, which
may occur at once or may be delayed. The blood loss could be either
seen externally or internally within a particular system or organ. The
greater the loss of blood, the greater the chance of developing shock.
A slow, steady loss of blood can also produce shock.
