Update

The advised practice for a patient who suffers a witnessed arrest en route to the hospital is to find a safe place to stop the ambulance and:

• Perform minimum one analysis.
• Utilize clinical judgement (utilizing multiple factors) to decide whether to stay and perform resuscitation:
  • Perform one analysis and go (likely the majority of situations where rhythm is non-shockable)
  • Perform three full analyses and go (ex. Persistent shockable rhythm)
  • Perform three full analyses and patch for direction if it is believed the patient would benefit from ongoing resuscitation in a stationary ambulance (this would be a rare occurrence).
