BASIC LIFE SUPPORT - ADULT
Basic life support (BLS) is the fundamental approach to saving lives following cardiac arrest.  Primary aspects of BLS include immediate recognition of sudden cardiac arrest and activation of the emergency response system, early cardiopulmonary resuscitation, and rapid defibrillation with an automated external defibrillator. Initial recognition and response to heart attack and stroke are also considered part of BLS.


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

Risk factors for 1-year mortality in heart failure (HF) patients significantly differ between those with and without chronic kidney disease (CKD), especially with regard to the use of beta-blockers or diuretics at discharge, according to a study. This suggests that these patients may benefit from individualized therapies.
