[Venous access and methods of drug application in ACLS (Advanced Cardiac Life Support)]

After initiation of cardiopulmonary resuscitation [CPR] with ventilation, chest compression and defibrillation when necessary, venous access, which allows administration of drugs and fluids, is the next measure. A large diameter peripheral vein should be the first choice and should be cannulated with a plastic catheter. If this is delayed or impossible, alternative routes such as central iv lines, intraosseous infusion or endobronchial drug administration should be considered.
