Supplement, The Truth about CPR
  • Pump for the Pump

    In a July article, "Danger in the Back of the Ambulance," Las Vegas Fire and Rescue Medical Director David Slattery, MD, notes that many factors and practices increase the risk of injury and death to providers and patients. These include routine critical-care patient procedures, such as compressions and ventilation, performed by unrestrained crew members en route to the hospital.

  • Ineffective Techniques

    The importance of chest compressions as the cornerstone of resuscitation has been confirmed by research in both animal and human subjects.(1-15) Indeed, in the absence of effective chest compressions, it appears most resuscitation efforts will be futile.

  • A Hands-On Approach

    In 2008, the American Heart Association (AHA) announced its support for "hands-only," or compression-only, CPR for lay bystander use in witnessed, out-of-hospital cardiac arrest in adults.(1) What is compression-only CPR, and what happens if we don’t immediately ventilate adult victims of sudden cardiac arrest. Finally, what does this mean for EMS?

  • Through the Years

    Just 5–15% of patients treated with standard CPR survive cardiac arrest, revealing a need for improved technique. To address this need, mechanical compression devices have become more prevalent and continue to evolve. Let’s take a look at the history of mechanical CPR devices and review their past and future in EMS.

  • Assess Your Adequacy

    Automated CPR devices are quickly gaining acceptance, especially since the 2005 American Heart Association (AHA) guidelines recognized that effective and uninterrupted cardiac compressions are critical to successful resuscitation.(1) These devices, however, do require a somewhat different approach in the use and evaluation of capnography in the cardiac arrest patient. In order to gain a better understanding of these differences, it’s important to first have an in-depth knowledge of the physiology of automated compressions and also of capnography.

  • Improved CPR

    We know that victims of cardiac arrest have a much higher chance of survival with bystander CPR.

  • Case Reports

    Traditional American Heart Association (AHA) training states that survival from cardiac arrest declines by 10% for every minute the brain goes without blood flow.(1) Although this is commonly used when discussing cardiac arrest without CPR, it’s also well recognized that traditional CPR provides less-than-adequate cerebral and cardiac perfusion.(2)

  • Options to Ensure Effective Compressions

    Once the EMS community has taken ownership of resuscitation and developed a plan for where resuscitations are going to be worked to completion, the greatest task is determining a method by which the quality of compressions can be assured. These range from personnel-intense to technologically-intense methods; the risks and benefits of each are discussed below. Unfortunately, the research is not yet complete regarding which of these methods is the most effective, and what is available is somewhat conflicting.

  • Measuring Quality

    CPR is one of the fundamental skills that EMS provides, yet most of us probably don't know the quality of the CPR that our system provides. Yes, we may be able to say that we've trained to the latest guidelines and have complete buy-in from our practitioners but can we quantify the "boast" that we provide "great" CPR?

  • Similarities & Differences in Three Case Reports

    Survival after cardiac arrest is reported in various resources with markedly varied rates of success. Survival after prolonged CPR is even less common and more often associated with poor neurologic outcomes. There are few reports of repeated successful outcomes in patients with prolonged CPR that don't involve unique circumstances, such as accidental hypothermia, massive pulmonary embolism and severe hyperkalemia.(1,2)

  • 17 Hurt When Maryland Buses Collide

    SILVER SPRING, Md. - Authorities say a Metro bus has rear-ended another Metro bus in Silver Spring, injuring 17 people.

    Montgomery County fire department Assistant Chief Scott Graham says the crash occurred just after 7 a.m. at University Boulevard West and Burnett Avenue. He says 17 people suffered non-life-threatening injuries, and that some were students from a local high school.

    Graham says the eastbound lanes of University Boulevard have been shut down.

    He says Montgomery County school officials are also at the scene.
