Did you know that during a cardiac arrest, the normal rhythmic contraction of the heart is disrupted? Instead of the usual controlled contractions, the heart undergoes ventricular fibrillation, meaning the lower chambers of the heart (ventricles) contract rapidly and uncontrollably. This life-threatening cardiac arrhythmia results in a chaotic rhythm, hindering effective blood circulation.
Ventricular fibrillation leads to severe consequences as there is insufficient blood being pumped to the body. This lack of oxygen can quickly lead to tissue damage and organ failure. In the case of a cardiac arrest, rapid intervention is crucial.
An automated external defibrillator (AED) is often deployed to restore the normal heart rhythm during ventricular fibrillation. The AED delivers a controlled electric shock to bring the heart back into a regular pattern. During a cardiac arrest, it is also essential to initiate cardiopulmonary resuscitation (CPR) immediately.
Understanding these processes emphasizes the urgent need for swift and effective responses in emergency situations. The use of AEDs and the application of CPR techniques play a crucial role in increasing survival rates and reducing the consequences of a cardiac arrest. It also underscores the importance of broad community awareness and training in life-saving skills.
