Randomized trial evaluates CPR strategies impacting cerebral blood flow and cardiac function in swine, suggesting outcomes for future research.

Evaluate the effects of three CPR strategies on cerebral blood flow, cardiac function, and 7-day survival outcomes.
Conducted a randomized trial in 4-week-old swine undergoing asphyxia and ventricular fibrillation arrest.
Administered three CPR strategies: HDhigh, HDlow, and AHA, with specific blood pressure targets and vasoactive doses.
Assessed cerebral blood flow using laser Doppler and post-resuscitation left ventricular function.
Chest compression depth and vasoactive doses varied significantly between CPR strategies.
Higher intra-arrest blood pressure led to lower cerebral blood flow in the HDhigh group compared to AHA.
Post-return of spontaneous circulation, cardiac function was less negative in HDhigh than in AHA, but 7-day survival rates were similar across all groups.

Herrmann et al. (2026) studied this question.
