after immediately initiating the emergency response system, what is the next link in the adult in-hospital cardiac chain of survival?

After immediately initiating the emergency response system in the adult in- hospital cardiac chain of survival, the next link is early high-quality cardiopulmonary resuscitation (CPR). This step focuses on providing effective chest compressions and ventilation to maintain blood circulation until advanced care can be provided. Early high-quality CPR significantly improves the chances of survival after cardiac arrest.
