Part 5: Adult Basic Life Support

The critical lifesaving steps of BLS are ● Immediate Recognition and Activation of the emergency response system ● Early CPR and ● Rapid Defibrillation for VF. When an adult suddenly collapses, whoever is nearby should activate the emergency system and begin chest compressions (regardless of training). Trained lay rescuers who are able and healthcare providers should provide compressions and ventilations. Contrary to the belief of too many in this situation, CPR is not harmful. Inaction is harmful and CPR can be lifesaving. However, the quality of CPR is critical. Chest compressions should be delivered by pushing hard and fast in the center of the chest (ie, chest compressions should be of adequate rate and depth). Rescuers should allow complete chest recoil after each compression and minimize interruptions in chest compressions. They should also avoid excessive ventilation. If and when available, an AED should be applied and used without delaying chest compressions. With prompt and effective provision of these actions, lives are saved every day.
