The pulmonary circulation loop is virtually bypassed in fetal circulation. [7] The fetal lungs are collapsed, and blood passes from the right atrium directly into the left atrium through the foramen ovale (an open conduit between the paired atria) or through the ductus arteriosus (a shunt between the pulmonary artery and the aorta).
The 'ABC' method of remembering the correct protocol for CPR is almost as old as the procedure itself, and is an important part of the history of cardiopulmonary resuscitation. Throughout history, a variety of differing methods of resuscitation had been attempted and documented, although most yielded very poor outcomes. [ 42 ]
In vertebrates, the circulatory system is a system of organs that includes the heart, blood vessels, and blood which is circulated throughout the body. [1] [2] It includes the cardiovascular system, or vascular system, that consists of the heart and blood vessels (from Greek kardia meaning heart, and Latin vascula meaning vessels).
Return of spontaneous circulation (ROSC) is the resumption of a sustained heart rhythm that perfuses the body after cardiac arrest. It is commonly associated with significant respiratory effort. Signs of return of spontaneous circulation include breathing, coughing, or movement and a palpable pulse or a measurable blood pressure.
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.
The first successful Norwood procedure involving the use of a cardiopulmonary bypass was reported by Dr. William Imon Norwood, Jr. and colleagues in 1981. [2] [3] Variations of the Norwood procedure, or Stage 1 palliation, have been proposed and adopted over the last 30 years; however, its basic components have remained unchanged.

Providers should follow the AHA's Pediatric Tachycardia With a Pulse Algorithm. As always, provides need to support airway, breathing, and circulation and begin CPR if needed. Management of tachyarrhythmias depends on if the child is stable or unstable (experiencing cardiopulmonary compromise: signs of shock, hypotension, altered mental status).
