What is High Performance CPR?

High Performance CPR typically consists of expertly performed BLS with strict attention to:

Minimally interrupted chest compressions

  • Ensuring optimal rate (100-120)
  • Ensuring adequate depth (2 – 2.4″ or 5 – 6 cm)
  • Allowing full chest recoil (avoid leaning)
  • Rotate rescuer on compressions every 2 minutes

Controlled ventilations

  • Only enough for chest rise (300 – 400 ml)
  • Pausing only 2-3 seconds to ventilate during 30:2
  • Asynchronous ventilations every 6 seconds once advanced airway is in place or every 10th compression

Defibrillation

  • Shocking on a 2-minute cycle
  • Pre-charging the monitor at 1:45
  • Minimize perishock pause to less than 5 seconds
  • Change out rescuer on chest compressions during perishock pause

This is essentially “The Seattle Way” but there are variations even within the Medic One system. They also practice what is called “BLS Continuous” which consists of continuous chest compressions with a ventilation interposed every 10th chest compression.

Minimally Interrupted Cardiac Resuscitation (MICR)

In Arizona they practice Minimally Interrupted Cardiac Resuscitation (MICR) — also known as Cardiocerebral Resuscitation (CCR) — for adult non-asphyxial arrest (important caveat) which consists of up to 4 cycles of continuous chest compressions with passive oxygen administration.

To argue about which approach is “better” misses the point until we have evidence that is definitive. Whatever method you employ, be an expert in that method and measure outcomes. That’s how we know what works and that’s what makes something “high performance.”

The science of resuscitation is always evolving. The idea is to develop a culture of continuous quality improvement. That’s easier said than done but it’s a worthwhile endeavor!

Establishing baseline performance at CPR University at the University of Arizona College of Medicine.

The 2015 AHA ECC Guidelines state: “For adults in cardiac arrest who receive CPR without an advanced airway, it may be reasonable to perform CPR with the goal of a chest compression fraction as high as possible, with a target of at least 60%.” This figure is surprisingly low. With HP-CPR the chest compression fraction can easily be over 80% and frequently over 90%.

To develop the correct muscle memory we strongly encourage the use of instrumented manikins. It’s the best way to perfect chest compressions and ventilations.
