Once the oxygenated blood reaches the left atrium, it travels through the left ventricle into the coronary arteries and aorta, which branches to provide the most oxygenated blood to the brain before a shunt from the pulmonary artery, called the ductus arteriosus, allows partially oxygenated blood to be combined to the blood supply that will then flow to the systemic circulation with an estimated oxygen saturation of 60%. However, in the management of PDA, NSAIDs like indomethacin may be given to close the shunt because it blocks the production of prostaglandins.
