  • Pathophysiology Case Study

    Pathophysiology One of the babies I cared for today was born at 33 weeks and was born with a patent ductus arteriosus (PDA). When the baby is in the mother’s uterus, the ductus arteriosus (DA) diverts blood from the pulmonary artery and moves it directly into the aorta, bypassing pulmonary circulation, because the lungs are not functioning and are filled with fluid. The DA opening is possible through the production of prostaglandins in the vessel allowing for it to stay patent (Kim, 2015, p.1). When the fetus is born the DA undergoes a transition, which occurs approximately 15-48 hours after birth and is this when the arteriosus constricts and closes. The blood is no longer shunted from the pulmonary artery to the aorta. Instead, it moves into a normal circulatory pattern. Normal circulation occurs when deoxygenated blood enters the right atrium and moves on through the right side of the heart to the pulmonary system where it is oxygenated and then moves back to the heart and out of the left ventricle to supply oxygen and nutrients throughout the body (Kim, 2016). A PDA occurs when the DA fails to close completely after delivery. When the DA vessel does not constrict and close, a left-to-right…

  • Patent Ductus Arteriosus: A Case Study

    The thought of a baby being born often warms the hearts of the parents to be. Hoping for the best in the creation and birth of their unborn child. It is until this moment that a parents’ world comes crashing down; the moment the doctor tells them that their precious child has a congenital cardiovascular defect known as Patent Ductus Arteriosus (PDA). The American heart Association describes the ductus arteriosus as a “hole that allows the blood to skip the circulation to the lungs”( The American…

  • Premature Birth Effects

    infections. He or she will be given extra nutrition to help with growth and development. There is also a risk of brain injury in babies born at this time, so they will be monitored. Short-Term Effects Having a premature birth can cause both short and long term effects on the baby. Some short term effects include problems with breathing, the heart, the brain, temperature control, and blood. When a baby is born too early, the lungs are not yet fully developed. If the baby is not getting enough…

  • Preterm Delivery

    Preterm delivery is a terrible problem that plagues the United States, as well as many other countries worldwide. Preterm delivery of infants remains one of the most intractable problems that contributes to perinatal morbidity and mortality (Slattery & Morrison, 2002). This issue contributes to a large amount of cost towards the health industry. The definition of preterm delivery is, “…those [deliveries] that occur at less than 37 weeks’ gestational age; however, the low-gestational…

    be stopped immediately. She respiratory status, heart rate, blood pressure, echocardiogram and heart sounds should be done routinely during therapy. Davis drug guide 9. If undetected and untreated, how might this baby’s condition have progressed? (1 point) If this is left untreated she could develop high blood pressure in the lungs (pulmonary hypertension). This happens when too much blood circulating through the heart’s main arteries through a patent ductus arteriosus can lead to pulmonary…

  • Placenta Case Studies

    that the blood from the right atrium travels directly to the left atria by use of the foramen ovale and then goes in the vicinity of the pulmonary circulation system. The ductus arteriosus maneuvers blood from the pulmonary artery to the aorta. Blood is then sent to the heart muscle and brain from the aorta. The blood will then go back to the right atrium of heart passing through the superior vena cava. The majority of the blood goes around the lungs through the ductus arteriousus to the…

  • Case Study Auscultate Caleb's Heart

    Another anatomical abnormality is patent ductus arteriosus—this condition is when two major arteries, the aorta and pulmonary, are connected and have abnormal blood flow and usually happens following birth. Before birth, the aorta and pulmonary arteries are connected by the ductus arteriosus for fetal blood circulation. However, immediately after birth up to a few days, the duct closes on its own as part of the normal development process. However, the duct doesn’t always close, which leads to…

  • Differences In Feetal Circulation Vs. Postnatal Circulation

    The second shunt the ductus arteriosus protects the lungs against circulatory overload and allows the right ventricle to strengthen. The last shunt, the ductus venosus is a fetal blood vessel connecting the umbilical vein to the inferior vena cava. The ductus venosus carries mostly oxygenated blood and is regulated via a sphincter. . In addition, the placenta connects to the fetus via an umbilical cord, which is made up of the umbilical vein and the two umbilical arteries. Thus, there are…

  • Cardiovascular System: Maintaining Homeostasis In The Body

    Examples that arise from too much blood moving to the lungs are Patent ductus arteriosus (PDA), Atrial Septal Defect (ASD), Ventricular Septal Defect (VSD), and Atrioventricular canal (AVC). In patent ductus arteriosus (PDA), the patent ductus arteriosus, a structure seen in all fetuses, fails to close. “Extra blood goes from the aorta into the lungs and may lead to "flooding" of the lungs, rapid breathing, and poor weight gain (Stanford). Atrial or Ventricular Septal defect occurs when there is…
