26 May Be Citizen Ready: Learn High-Quality CPR – Paramedic Services Week 2021 Blog Series

While Cardiopulmonary Resuscitation (CPR) has changed many times over the years with new research and technology, the desired outcome from CPR efforts has not.

The evolution of CPR has included an increased focus not only on WHAT we are doing or HOW we are doing, but also on the WAY we are doing it to achieve the most effective result. While the mechanics of CPR have remained relatively the same, greater focus is given to ensuring these mechanics are effective and not detrimental to our efforts. The more we know about why we are doing what we are doing or teaching, the greater likelihood these treatments will be successful in improving outcomes from sudden cardiac arrest.

The Dos and Don’ts of Adult High-Quality CPR*

High Quality CPR is a critical component in the success of survival from a sudden cardiac arrest. Simply put, it is an organized approach to significantly improve the quality of resuscitation for Sudden Cardiac Arrest (SCA) and the chance for survival of the affected person. CPR practices that reflect the concepts below are rapidly being adopted by healthcare providers and organizations and filtering into the public in modified applications where appropriate.

Some of the more important metrics include:

  • Push hard and push fast
  • Compression rate of 100-120/min
  • Compression depth of at least 5cm (2 inches) in adults and ≥1/3 the A/P diameter of the chest in infants and children*
  • Allow the chest to completely “recoil”
  • “Hands-On” Time (maximize) and “Hands-Off” Time (minimize)
  • No excessive ventilation (breaths)
  • Change the person doing the compression every 2 minutes

 

Details Matter
Research indicates that higher-quality skills, especially concerning chest compression, provide a higher chance for surviving Sudden Cardiac Arrest (SCA).

  • Peak survival for SCA occurs at a compression rate of around 100-120 compressions per minute.
    The deeper the compression, the higher the survival rate. Compressions of at least 5 cm or 2 inches are recommended. Minor injury can occur with deeper compressions, but that should not prevent getting the deepest compression possible.
  • Full chest recoil to normal position on the upstroke of compressions is critical. The effect of recoil on blood flow and SCA survival is significant and should not be underestimated.
  • Blood pressure is created and maintained with ongoing compressions. When compressions stop, even for a short time, blood pressure is lost and has to slowly be built back up. Minimizing interruptions to compressions improves quality and survival.
  • Excessive air volume in rescue breaths can result in complications that reduce the quality of the effort.
  • Minimizing the interruption time of compressions before and after defibrillation can improve survival. With a team, the integration of using an AED when one arrives can go much more smoothly and without interrupting compressions. Compressions can be started immediately after a defibrillation shock is delivered.
  • Performing chest compressions is tiring. It is unlikely a provider can maintain high-quality compressions for more than 2 minutes. Seamlessly switching compressors every 2 minutes can help maintain compression quality.

 

Quality Matters
In areas where a higher focus is made on the quality of resuscitation, survival rates can go up remarkably, even as high as 40-60%, compared to 10–14% for outdated CPR practices. Without high-quality CPR, the likelihood of survival falls by an estimated 5–10% each minute.

For the past decade, the consensus expert view on resuscitation is that we are pretty well-versed on how to do it, but not as much so in regards effective technique. There is a clear gap between what we know about how to do CPR and our actual ability to perform it well. Narrowing this gap should be a priority.

More on ZOLL’s cutting-edge CPR systems

Rescuers at every experience level need assistance when delivering high-quality, high-performance CPR. Systems, both in and out of the hospital, that have focused on improving CPR quality and have incorporated ZOLL technology, have doubled the odds of survival.

The Real CPR Help® technology on ZOLL AEDs (Automated External Defibrillators) and other professional defibrillators assists in delivering high-quality CPR. Real CPR Help® provides visual and audio feedback that guides rescuers to deliver CPR compressions fast enough and deep enough to save a life. On ZOLL’s professional defibrillators, the CPR Dashboard™ displays detailed information, including the rate and depth of every compression and whether full release is being achieved. In addition, See-Thru CPR® technology filters out compression artifact so that the patient’s underlying heart rhythm can be displayed during CPR, minimizing the duration of pauses. And through Real CPR Help® technology, all of the key data from the rescue effort is recorded and can be easily accessed for post-event debriefing and training.

Studies show that in over 90% of cases, ventilation delivery is either excessive or insufficient and that the average rate can exceed over 30 ventilations per minute. Poor ventilation quality likely occurs due to a lack of real-time feedback. In its 2020 Guidelines for CPR and ECC, the Heart and Stroke Foundation of Canada states: “It is strongly recommended in advanced courses, to bring the integration of feedback devices that provide feedback on ventilation rates aligned with the most recent Guidelines Update for CPR and ECC. This is not a requirement at this time; however, it may become mandatory in the near future.”

ZOLL® is proud to introduce Real BVM Help™, a ground breaking new technology available only on ZOLL’s new X Series® Advanced monitor/defibrillator. Real BVM Help provides clinicians with real-time ventilation feedback on both rate and volume for patients managed with a simple BVM or an advanced airway.
