Review Meta Analysis
When should chest compressions be paused to analyze the cardiac rhythm?: A systematic review and meta-analysis.
Most guidelines recommend pausing chest compressions at 2 min intervals to analyze the cardiac rhythm. We conducted a systematic review and meta-analysis to define the optimal interval at which to pause chest compressions in adults for cardiac rhythm analysis in any setting. ⋯ There is a paucity of quality evidence to support pausing chest compressions at any singular interval to assess the cardiac rhythm in adults in cardiac arrest in any setting. Very low-quality evidence suggests improved clinical outcomes in patients receiving 200-compression intervals compared with 1- or 3 min intervals.
