Experimental: Control

Standard ICU resuscitation practices throughout study

Experimental: OPTI-VENT Bundle

Provider Education: During a brief (\<2 minute) bedside education, the educator will 1) review the CPR ventilation rate targets for age, and 2) ensure the provider has a cue card of current rate recommendations on his/her person. Compliance will be defined as performance of at least 30 trainings per unit per month. We will record provider discipline and time since last training as a surrogate of training spread. Educators will leverage these two-minute trainings to review the patient's current ventilator settings as an initial target during CPR to ensure adequate chest rise.~Additionally, a focus on CPR ventilation rates will be integrated into resuscitation education or quality meetings for all disciplines. Report cards detailing unit-level performance will be generated by the study team for review during site monthly presentations.~Point-of-Care Guidance: A metronome will be deployed to all cardiac arrests using a smart phone application.
