In healthcare, Advanced cardiac life support is "the use of sophisticated methods and equipment to treat cardiopulmonary arrest. Advanced Cardiac Life Support (ACLS) includes the use of specialized equipment to maintain the airway, early defibrillation and pharmacological therapy."

Treatment

Basic life support should include chest compressions done for at least 60% of the duration of the period without pulse.[1] The effect of chest compressions may be helped by active compression-decompression with a device such as ResQPOD.[2][3][4]

Artificial respiration may be needed.

Clinical practice guidelines for advanced cardiovascular life support by the American Heart Association provide treatment algorithms:[5]

Ethical issues

When not to start ACLS

In a particular jurisdiction, this may have legal constraints, or operational ones such as standing orders from the medical director of an emergency medical system (EMS). This kind of emotionally draining decision is apt to be most straightforward when a patien's medical records are readily available and contain an explicit "Do Not Resuscitate" (DNR) or "Do Not Attempt Resuscitation" request from the patient or a surrogate with the appropriate authority.

This can be much more difficult in the field. Most EMS systems have rules for the obvious cases when any life support would be futile, such as decapitation or decomposition. A current controversy deals with certain kinds of trauma, where, variously,

  1. With reasonable medical certainty, there is no possibility of resuscitation with all possible resources. Finding a victim who is pulseless and has sustained major blunt chest trauma is the usual example where death is not obvious
  2. Studies are ongoing about when ACLS is futile for out-of-hospital arrests.[9]
  3. Situations where ACLS will not help, but immediate surgical intervention has some chance. Current thinking is that the appropriate treatment for exsanguinating hemorrhage is not fluids, not ACLS, but immediately opening the chest for manual heart compression and, perhaps, emergency repair or control of a vascular injury. In such a situation, if there is minimal but not absent cardiac activity, and there is a facility nearby prepared for emergency thoracotomy, the ACLS "treat until stable" is less appropriate than "scoop and run".

When to terminate ACLS

A clinical prediction rule suggests advice about stopping ACLS that is in progress.[10][11]

The Ontario Prehospital Advanced Life Support (OPALS) recommendation is "termination of resuscitation when there was no return of spontaneous circulation prior to transport, no shock was given and the arrest was not witnessed by Emergency Medical Services personnel."[11]
