A joint statement from the British Medical Association, the Resuscitation Council (UK) and the Royal College of Nursing Health professionals are aware that decisions about attempting cardiopulmonary resuscitation (CPR) raise very sensitive and potentially distressing issues for patients and people emotionally close to them. Some health professionals do not find it easy to discuss CPR with their patients, but this must not prevent discussion, either to inform patients of a decision or involve patients in the decision-making process, where appropriate. These guidelines identify the key ethical and legal issues that should inform all CPR decisions. These basic principles are the same for all patients, in all settings, but differences in clinical and personal circumstances make it essential that all CPR decisions are made on an individual basis. The guidelines provide a framework to support decisions relating to CPR and communicating them effectively.
