Check adult victim’s responsiveness

• Rescuer should ensure that the scene is safe & immediately check for response
• Quickly assess for responsiveness by gently tapping the victim on the shoulders & asking loudly “are you alright?”
• Assume cardiac arrest if there is unresponsiveness, abnormal breathing (ie gasping) or absence of breathing
  
  • Brief, generalized seizures may be the initial presentation of cardiac arrest

• Assessment should take no longer than 10 sec
