Document Summary
Labor assessment & electronic fetal monitoring (efm: types of fetal monitoring (external vs. internal). Names and what they measure : external: ultrasound transducer or doppler records the fetal heart rate and. Tocodynamometer records the frequency and duration of the contractions. Gives a printed record of the heart rate and contractions and makes heart sounds audible: internal monitoring (requires a rupture of membranes) Fetal scalp electrode (fse): attached to the baby"s scalp to record the electrical conduction of the fetal heart. There is no reliable method of determining fetal distress using a doppler except extreme changes in heart rate: continuous monitoring: monitoring both fetal heart rate and contractions continuously. Mother must stay in bed, often shows both false positive and negative results, and has been shown to lead to unnecessary interventions like c- sections. Can also be used to estimate fetal weight: external version: the process by which a breech baby can sometimes be turned so that it is head first.
