Ventricular fibrillation in conscious patients witnessed by the emergency medical service

Published:February 02, 2018DOI:https://doi.org/10.1016/j.ajem.2018.02.002
      Current Resuscitation Guidelines endorse a simple evaluation to recognize cardiac arrest; an unconscious and not normally breathing victim. This simple algorithm may not completely align with the physiological reality of cardiac arrest (CA). Some studies state that during the first minute of a witnessed ventricular fibrillation (VF) breathing patterns could remain normal. Likewise, the level of consciousness could be maintained for a short period of time, which contradicts the current guidelines.
