Cardiopulmonary resuscitation (CPR) is an emergency procedure consisting of chest compressions often combined with artificial ventilation, or mouth to mouth in an effort to manually preserve intact brain function until further measures are taken to restore spontaneous blood circulation and breathing in a person who is in cardiac arrest.
ILCOR produced the first International CPR Guidelines in 2000, and revised protocols in 2005 (published concurrently in the scientific journals Resuscitation [2] and Circulation). [3] A total of 281 experts completed 403 worksheets on 275 topics, reviewing more than 22000 published studies to produce the 2005 revision.
As of December 2005, advanced cardiac life support guidelines have changed significantly. A major new worldwide consensus has been sought based upon the best available scientific evidence. The ratio of compressions to ventilations is now recommended as 30:2 for adults, to produce higher coronary and cerebral perfusion pressures.
Advanced cardiac life support, advanced cardiovascular life support (ACLS) refers to a set of clinical guidelines established by the American Heart Association (AHA) for the urgent and emergent treatment of life-threatening cardiovascular conditions that will cause or have caused cardiac arrest, using advanced medical procedures, medications, and techniques.
The LUCAS can be used both in and out of the hospital setting. [6] [7] The 2015 European Resuscitation Council Guidelines for Resuscitation does not recommend using mechanical chest compression on a routine basis, but are good alternative for situations where it may be difficult or to maintain continuous high-quality compressions, or when it may be too strenuous on the medic to do so.

The CPR mask is the preferred method of ventilating a patient when only one rescuer is available. Many feature 18 mm (0.71 in) inlets to support supplemental oxygen , which increases the oxygen being delivered from the approximate 17% available in the expired air of the rescuer to around 40-50%.
