In an advanced emergency medical service all parts of the advanced life support (ALS) algorithm can be provided. This evidence-based algorithm outlines resuscitative efforts for the first 10-15 minutes after cardiac arrest, whereafter the algorithm repeats itself. Restoration of spontaneous circulation fails in most cases, but in some circumstances the patient may benefit from additional interventional approaches, in which case transport to hospital with ongoing cardiopulmonary resuscitation is indicated. This paper has summarized treatments outside the ALS algorithm, which may be beneficial, but are not supported by firm scientific evidence.
