Document Summary
Modes or types of fetal and uterine monitoring. The use of the doppler to hear tat fhr by external listening. An ultrasound device to detect fr and a pressure device to assess uterine activity. A fetal scalp electrode/internal scalp electrode that is applied to the presenting part of the fetus. Monitor paper used for the electronic fetal monitor. Awhonn standards for frequency of assessment of fhr. Frequency of fhr assessment is based on: risk status, stage of labor, and ongoing clinical assessment. 10-15% of maternal cardiac output perfuses the uterus per minute. Primarily mediated by vagus nerve innervating sinoatrial and atrioventricular node of the heart. Stimulation produces an increase in strength of fetal heart contraction. Stretch receptors in the aortic arch and the carotid arch. The integrative center responsible for variations in fhr and baseline variability related to fetal activity. Located in the aortic arch and the central nervous system. Respond to changes in fetal o2 and co2.
