A cardiac arrest occurs when
the ticker suddenly stops pumping blood around the body mainly because of a
problem with electrical signals in the heart. When the ticker stops pumping
blood, the brain is starved of oxygen which causes unconsciousness in an individual
and the victim stops breathing.
Cardiac Arrest Signs:
There are generally no
symptoms before a cardiac arrest and, it can be fatal without immediate
treatment. A victim in cardiac arrest won’t be conscious, they won’t be
responsive and won’t be breathing, or breathing normally. A cardiac arrest is a
life-threatening medical emergency and a victim would require immediate
treatment for survival. If you witness a cardiac arrest, immediately dial 911
and give CPR to increase the person’s chances of survival.
For a CPR certification Tampa, sign up in a certified training site such
as the AHA certified CPR Tampa in Florida. Both theoretical and practical
training are imparted to the students by certified instructors.
Cardiac Arrest Causes:
The most common cause is a
life-threatening abnormal heart rhythm called Ventricular Fibrillation (VF)
which happens when the electrical activity of the ticker becomes so chaotic
that it stops pumping and quivers or 'fibrillates' instead. Some heart-related
causes include coronary heart disease, heart attack, congenital heart disease,
heart valve disease, cardiomyopathy and some inherited heart conditions, acute
myocarditis (inflammation of the heart muscle), ticker conduction disorders
that increases the likelihood to experience abnormal heart rhythms, such as
Long QT syndrome.
Other causes include
electrocution, drug overdose, drowning, severe haemorrhage.
Recovering from a Cardiac Arrest:
Training in how to use an AED
device for the process of defibrillation is imparted in the CPR classes itself.
VF can sometimes be corrected by giving an electric shock through the chest
wall, by using an Automated External Defibrillator device which can be done by
a member of the public (using a public access defibrillator), the emergency
services or at hospital. The device is easy to use, it is just required to
follow the voice instructions. But training will instil confidence in carrying
out the task competently during an out-of-hospital cardiac emergency.
Performing CPR (a series of
chest compressions and rescue breaths) will keep oxygen circulating around the
body until a defibrillator can be used and/or until the emergency services
arrive.
Difference between Cardiac Arrest and Heart Attack:
Blood supply to the heart muscle
being cut off due to a clot in one of the coronary arteries is what causes a
heart attack which can cause chest pain, although symptoms can be less severe,
and can permanently damage the ticker. On the
other hand, when the ticker
suddenly stops pumping blood around the body, often because of a problem with
the electrical signals to the heart muscle is what leads to a cardiac arrest.
