It is well-accepted that good, rapid compressions are one of the best interventions we can employ in managing patients with cardiac arrest. It is imperative that we minimize interruptions. Unfortunately, delivering shocks to a patient is a frequent cause of interruptions in compressions. It now appears that we may not need to discontinue compressions during shocks.

A recent study indicates that if shocks are delivered using the common self-adhesive pregelled pad electrodes and the person performing compressions is wearing gloves, the rescuers do not sense a shock at all. Compressions, therefore, do NOT have to stop during the cardioversion or defibrillation.

Whether this statement is true regarding handheld manual defibrillators also is uncertain.
