This chapter discusses about the cardiopulmonary resuscitation which is carried out as per the basic life support (BLS) and advanced cardiac life support (ACLS) latest guidelines of the American Heart Association. Team composition involves anesthetist, cardiologist, resident medical officer, nurse taking care of that particular patient, and the ICU/CCU nurse/nurse team leader of that floor. Cardiopulmonary resuscitation steps are documented in order to facilitate accurate and complete documentation of code occurrences, and action taken and to provide a record for review, and evaluation of CPR and the advanced life support measures.
