Cardiac arrest & resuscitation
Implications of an individualized resuscitation strategy using continuous rhythm and physiologic status assessment during ongoing CPR
Authors' conclusion
An individualized resuscitation strategy could improve CPR interruption, medication administration, shock delivery, and pulse assessment.
