Answer

Answer

Although prompt defibrillation has been shown to improve survival for VF and pulseless VT rhythms, [26] CPR should be started before the rhythm is identified and should be continued while the defibrillator is being applied and charged. Additionally, CPR should be resumed immediately after a defibrillatory shock until a pulsatile state is established. This is supported by studies showing that “preshock pauses” in CPR result in lower rates of defibrillation success and patient recovery. [27]
