Resuscitation
-
Prior studies have proposed defibrillator biosignal algorithms which characterize cardiac arrest rhythm and physiologic status. We evaluated whether a novel, individualized resuscitation strategy that integrates multiple ECG and impedance-based algorithms could reduce CPR interruptions and better align rescuer actions with patient-specific physiology. ⋯ An individualized resuscitation strategy could improve CPR interruption, medication administration, shock delivery, and pulse assessment. Prospective evaluation is required to assess clinical benefit.
