high-quality BLS management of cardiac arrest is essential. This includes ensuring CPR and ventilation quality including the use of feedback devices and measuring and providing feedback of performance. Once the BLS stuff is taken care of, treatment/management should be dictated by the patient. This may or may not prioritize the airway.

Perhaps most important, is early access and early drug administration. The evidence points that IV access may be better than IO and that medications are still useful, especially early during the resuscitation.
