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.
