Relias - Fetal Heart Monitoring With Complete Questions And Answers Latest Version 2024-2025 Relias - Fetal Heart Monitoring With Complete Questions And Answers Latest Version 2024-2025 uterine blood supply - uterine arteries deliver oxygenated blood to spiral arteries which bring oxygen rich blood to intervillous space of placenta that has fetal capillaries - fetal capillaries carry the O2 rich blood to umbilical VEIN that goes to fetus -in contrast, the umbilical ARTERIES return waste products to that intervillous space that go into mother's venous system Potential issues that negatively affect fetal oxygenation Maternal Oxygenation: asthma, hyper- or hypo- ventilation Maternal Circulation: decreased maternal cardiac output, hypotension, decreased Hgb Placental O2 and CO2 Exchange: postterm, abruption, HTN, hypotension, uterine tachysystole Fetal circulation: cord compression or occlusion Fetal hypoxemia - can occur d/t reduced fetal O2 reserves, excessive uterine activity, or reduced uteroplacental blood flow- worsening fetal hypoxemia can lead to abnormal FHR patterns, mostly minimal or absent variability from acidemia (1) hypoxemia vs. (2) hypoxia 1 - reduce O2 in blood 2 - reduced O2 delivery at tissue level Fetal anaerobic metabolism - occurs when long term O2 delivery is insufficient to meet cellular needs of tissues - results in production
