ACLS was designed as a framework, not a rigid playbook. It is intended to raise the floor of resuscitation quality without constraining expert clinical judgment. Here are 5 practical ways to optimize care :

​

1.      Prioritize Continuous Cerebral Perfusion: Pausing CPR causes blood flow to drop instantly; following a 10-second pulse check, it takes up to 40 seconds to restore adequate cerebral perfusion pressure. Focus on uninterrupted perfusion quality. Consider mechanical CPR devices during extended arrest or cath lab procedures.

​

2.      Check Rhythms, Not Pulses:  Don’t pause compressions to feel for a pulse if the monitor displays an unorganized or non-perfusing rhythm. If no organized rhythm is present, immediately resume chest compressions.

​

3.      Utilize Pre-charging and Extended CPR Cycles: Give a 15-second warning before rhythm checks to ensure ultrasound is ready, the pulse checker is in position, arterial lines are clear, and the defibrillator is charged. When there is no expectation of an immediate rhythm change, extending CPR cycles beyond 2 minutes (e.g., 4 minutes) significantly increases total cerebral perfusion time.

​

4.      Optimize Vector and Defibrillation Strategy: Anterior-Lateral pad placement misses up to 10% of the left ventricle, increasing the risk of re-propagating V-Fib/V-Tach. Transition to Anterior-Posterior placement to capture more myocardium. Deploy Dual Sequential Defibrillation to add a second vector and reduce transthoracic impedance in refractory V-Fib.

​

5.      Limit Epinephrine and Use Early Vasopressors for Low-Flow States: Repeated epinephrine every 3 minutes improves initial ROSC rates but may worsen neurologically intact survival.  Utilize cardiac ultrasound to evaluate contractility, and consider initiating a high-dose norepinephrine infusion during CPR to recruit marginal output and convert pseudo-PEA into a palpable rhythm.
