Sudden Cardiac Arrest A Heart in Distress Uncoordinated, very fast heart rhythm Ventricular fibrillation (VF) Ineffective heart pump Unconscious, no breathing, no pulse Death certain without defibrillation Red Wings defenseman Jiri Fischer
The Case for Early CPR CPR circulates oxygen enriched bloodthroughout the victim whose heart isno properly pumping Early CPR will prolong VF (the window of time during which defibrillation can occur) CPR alone will not eliminate VF An interruption in CPR is associated with a decreased probability of conversion ofVF to another rhythm AHA Circulation. 2005;112:IV-35-IV-46, Part 5

Defibrillation plus CPR – A Critical Combination An AED detects an abnormal rhythm and sends an electrical current to stopthis rhythm to allow the heart torestart with a normal beat After the shock is delivered, thenimmediately resumeCPR until the victimbegins to move An AED will reanalyze the victim every 2 minutes. This analysis should take less than 15 seconds AEDs are of no value for arrest not caused by VF AHA Circulation. 2005;112:IV-35-IV-46, Part 5
OSHA Best Practices Guide All worksites are potential candidates for AED programs because of the possibility of SCA and the need for timely defibrillation. The training program should be designedor adapted for the specific worksite and may include first-aid instruction in … performing CPR and using an AED. Instructor-led retraining for lifethreateningemergencies should occur at least annually.
Q & A about an AED What if the victim has a pulse and I can’t feel it? Can I hurt someone using the AED? Is there legal liability?
Can not make things worse
All AEDs are designed to shock only when needed
