Chapter 92: Cardiopulmonary and Cardiocerebral Resuscitation
Which of the following statements concerning out-of-hospital cardiac arrests is incorrect?
A. A family history of cardiac arrest in a first-degree relative is associated with a twofold increase in the risk of cardiac arrest
B. The majority of out-of-hospital cardiac arrests occur at a home or residence
C. The median age for out-of-hospital cardiac arrest is 66 years
D. The incidence of cardiac arrest with an initial rhythm of VF is decreasing over time
E. The incidence of cardiac arrest is decreasing
The answer is E. (Hurst’s The Heart, 14th Edition, Chap. 92) The American Heart Association (AHA) statistical data from 20151 reveal that the incidence of cardiac arrest is not decreasing, but the incidence of cardiac arrest with an initial rhythm of VF is decreasing over time (option D).2 The median age for out-of-hospital cardiac arrest is 66 years (option C). According to the CARES registry, in 2013 most out-of-hospital cardiac arrests occurred at a home or residence (69.5%).3 A family history of cardiac arrest in a first-degree relative is associated with a twofold increase in the risk of cardiac arrest.4-5
You are speaking with your patient and his family in the coronary care unit after he underwent coronary percutaneous intervention for an anterior ST elevation myocardial infarction. The patient’s wife asks about the utility of learning cardiopulmonary resuscitation (CPR) in the event that her husband has an arrhythmic event. Which of the following statements is incorrect?
A. Untrained lay rescuers should provide compression-only (hands-only) CPR, with or without dispatcher guidance, for adult victims of cardiac arrest
B. The rescuer should continue compression-only CPR until the arrival of an AED or rescuers with additional training
C. All lay rescuers should, at a minimum, provide chest compressions for victims of cardiac arrest
D. If the trained lay rescuer can perform rescue breaths, he or she should add rescue breaths in a ratio of 15 compressions to 2 breaths
E. The rescuer should continue CPR until an AED arrives and is ready for use, EMS providers take over care of the victim, or the victim starts to move
The answer is D. (Hurst’s The Heart, 14th Edition, Chap. 92) Favorable neurologic outcome at discharge was observed in patients who were treated under the 2005 guidelines with a compression-ventilation ratio of 30:2, with a slightly higher survival than those patients treated under ...
