In cardiac arrest, it has been demonstrated that pauses in chest compressions are correlated with poorer outcomes,1–3 with one study demonstrating a decreased odds of survival with each additional 5-s pause.2 Interruptions in chest compressions lead to cessation of blood flow to the coronary and cerebral circu- lation and require significant time to re-attain the flow rates approximating those immediately preceding the cessation.3 This has been hypothesized as one of the primary etiologies for the decreased survival rates seen in patients with prolonged pauses in chest compressions
