Advanced cardiac life supportAdvanced cardiac life support (ACLS)
is a detailed medical protocol for the provision of lifesaving cardiac care in settings ranging from the pre-hospital environment to the hospital
is the appropriate medical response to cardiac arrest
and is continued until the person is revived or is declared dead
by competent medical authority.
CPR or cardiopulmonary resuscitation is the lowest level of ACLS. CPR provided by laypersons buys time for higher medical responders to arrive and to transport the victim to more advanced medical care. For this reason it is essential that any person starting CPR also activate the emergency medical services by calling for help using the emergency telephone number.
An important advance in providing ACLS is the availability of the automated external defibrillator or AED, which can be used by a layperson to deliver defibrillation.
Semi-automatic defibrillation, oxygen and airway support may be provided by emergency medical technicianss.
Advanced cardiac drugs, manual defibrillation and intubation may be provided by paramedics.
A doctor trained in emergency medicine can provide additional cardiac drugs and surgical intervention including cardiac massage.
