Questions and Answers

What is the most critical factor in ensuring a victim's survival in case of a sudden cardiac arrest?

  • Rapid notification of the emergency response system (correct)
  • Presence of an Automatic External Defibrillator (AED) nearby
  • Prompt arrival of an ambulance
  • Administration of CPR by a bystander

What is the primary purpose of initiating CPR on a victim of sudden cardiac arrest?

  • To treat the underlying cause of the cardiac arrest
  • To ensure the victim's brain function is preserved
  • To provide temporary circulation until medical help arrives (correct)
  • To delay the arrival of medical help

What is the likely outcome if emergency care is not rendered within the first few minutes of a sudden cardiac arrest?

  • Full recovery of the victim
  • Permanent brain damage
  • The victim will experience cardiac arrest again
  • The victim will likely not recover (correct)

Study Notes

Development of CPR Programs

  • A CPR program was developed and taught to emergency room physicians after determining its effectiveness in combating sudden cardiac arrest.
  • By the late 1950s and early 1960s, a civilian cardio-pulmonary resuscitation program was developed to combat the high incidence of heart disease and sudden cardiac arrest in America.
  • In 1963, a CPR committee was formed to start a "life-saving" campaign that would teach cardiopulmonary resuscitation (CPR) to citizens with no medical background.

Importance of CPR

  • According to a 2015 report, there are 326,000 cases of out-of-hospital sudden cardiac arrests each year in the US.
  • Only one in five American adults know how to appropriately and/or effectively perform cardiopulmonary resuscitation.
  • Heart disease encompasses a wide variety of conditions and ailments that can lead to a person's premature death.
  • Victims of sudden cardiac arrest normally suffer from either a massive "sudden death" heart attack or a lethal electrical disturbance in the heart called dysrhythmia.

Chain of Survival

  • The initial treatment for sudden cardiac arrest remains the same regardless of the cause.
  • Someone nearby must realize that a life-threatening event is occurring and quickly call for professional help (911).
  • Rapid notification of the emergency response system (911) and being prepared to deliver effective CPR are crucial "links" in the chain of survival.
  • The entire chain is required to successfully resuscitate a victim of sudden cardiac arrest.

Bystander Response

  • To prevent the progression to irreversible brain death, bystanders should:
    • Recognize an emergency exists that requires CPR.
    • Call for help and request bystanders to locate an AED and bring it to you.
    • Perform high-quality CPR while awaiting an AED/defibrillator or the EMS unit to arrive.
  • Initiating the call for help is a great first step, but it is not going to be enough to save a victim's life, in most cases.
  • Intervention can only help in a medical emergency, and it is crucial to remember that if only one link of the chain is weak or missing, the chances of survival decrease.

High-Quality CPR

  • High-Quality, "Fast-n-Hard" Cardiopulmonary Resuscitation is crucial in saving a victim's life.
  • The human body is strong, but without a continuous supply of oxygen being delivered to the body, the vital organs will quickly begin to shut down.

The Chain of Survival (Detailed)

  • Early recognition that an emergency requiring assistance is occurring.
  • Early "fast-n-hard" cardiopulmonary resuscitation.
  • Early defibrillation with AED/defibrillator.
  • Early advanced life support by EMS/fire dept.
