Role of Bystanders and Chain of Survival Links to Save SCA Victims

Introduction to Sudden Cardiac Arrest 

Sudden cardiac arrest refers to unexpected and sudden zero pulses. The condition occurs from a disturbance in the electrical activity of a victim’s heart. The disturbance may occur by a heart attack and an imbalance of electrolytes in its severe form. Luckily, SCA victims can get temporary relief from bystanders who have CPR Certification with knowledge and expertise in the respective field.

In some cases, SCA takes place by an inherited form of genetic mutation, as it predisposes the patients’ hearts to various electrical abnormalities. Moreover, electrical shock due to lightning or blunt force trauma caused to the chest may result in cardiac arrest.

Sudden cardiac arrest conditions usually do not have any symptoms. However, when a symptom takes place, it involves an instant loss of consciousness. The main objective of the SCA treatment as CPR is to gain a good neurological outcome based on the restoration of a healthy cardiac rhythm.

Statistics on Sudden Cardiac Arrest 

Every year, the condition of sudden cardiac arrest strikes 3 lacs to 4 lack of people outside hospitals in different areas of the United States. These will include an estimation of 6,000 people below 18 years of age.

Approximately one in 10 victims survive even though a few high-performing groups have gained 60 percent of survival rates in different forms of cardiac arrest. The consistent increase in the number of SCA victims has led to the emergence of the BLS training program.

How Bystanders Can Save Lives 

Many people who survive the condition of sudden cardiac arrest invariably get help immediately from bystanders with BLS Certification available at the scene. The time between the cardiac arrest onset and the care provider determines the survival likelihood of a patient. If the patient does not get treatment within only 10 minutes, the survival rate becomes almost zero.

A single minute matters a lot for SCA patients. Hence, bystanders play a vital role in saving lives and preventing brain damage of sudden cardiac arrest patients. Individuals who want to be a bystander only have to search CPR Classes near me and complete their certification program.

Chain of Survival in CPR 

Chain of Survival taught in CPR Classes refers to the chain of different events, which should take place rapidly and in succession to boost the chance of a patient’s survival from sudden cardiac arrest. The term initially includes early access, early recognition, early CPR, and early defibrillation with early advanced life support.

However, the American Heart Association adopted the concept later and emphasized the significance of early response and recognition. The AHA expanded the concept of chain of survival with options to impart post-resuscitation care and incorporated mild therapeutic hypothermia and related treatments.

After a few years, the association and every institute organizing CPR certification has included an additional link referred to as integrated care for post-cardiac arrest in the existing Chain of Survival. Every bystander undergoing a CPR training program should know to use the necessary First Aid Kit and stay aware of the links present in the Chain of Survival.

Therefore, with the knowledge and expertise of Chain of Survival associated with cardiopulmonary resuscitation, bystanders may save the lives of SCA victims.
