Case of the Month - "High Performance CPR"


Questions and Answers
  • 1. 
    The “Chain of Survival” concept popularized by the American Heart Association describes critical factors that influence successful resuscitation from cardiac arrest.  The initial emphasis of the original version of the chain, however, was limited to:
    • A. 

      The timeliness of initiation of CPR, defibrillation, and further advanced care

    • B. 

      Recommending specific drugs to use in cardiac arrest

    • C. 

      Improving 911 systems for better bystander recognition of cardiac arrest

    • D. 

      All of the above

  • 2. 
    “High Performance” CPR emphasizes what additional factors in resuscitation?
    • A. 

      Arranging rapid transport to specialty cardiac centers

    • B. 

      Recommending that ALS capability be immediately available to maximize chance of survival

    • C. 

      Paying close attention to ongoing CPR quality, instead of just early initiation

    • D. 

      None of the above

  • 3. 
    A critical parameter in High Performance CPR is compression “fraction time,” which describes the percentage of time spent actively providing compressions vs. pausing for other actions (pulse/rhythm checks, airway management, etc.).  Practices that help maintain a high (> 80%) compression fraction include:
    • A. 

      Utilizing a “pit crew” team approach with coordinated roles to accomplish critical tasks simultaneously

    • B. 

      Using clear communication practices between team members

    • C. 

      Considering using an approved mechanical compression device when appropriate to remove compressor fatigue as a factor

    • D. 

      All of the above

  • 4. 
    The statement that “EMTs own CPR” refers to the concept that:
    • A. 

      Compressions should only be performed by BLS personnel while ALS providers focus on “advanced” procedures

    • B. 

      Out of hospital cardiac arrest is a medical emergency that is essentially solved (or not) by BLS measures

    • C. 

      All resuscitation team members are responsible for “quality control” to ensure effective CPR

    • D. 

      Both B & C

  • 5. 
    Advanced procedures, including definitive airway management and vascular access:
    • A. 

      Are crucial to patient survival and a priority to get established as soon as ALS providers reach the patient

    • B. 

      Can be attempted while CPR is in progress to minimize interruptions in compressions

    • C. 

      Are separate from the High Performance CPR model, which only involves BLS interventions

    • D. 

      All of the above
