Measures
This new test is performed inside the a quiet space having a nice temperatures in which the patient was operating out of lateral dorsal decubitus that have a somewhat correct otherwise left rotation to support the newest research, as well as Doppler measurements were obtained about absence of maternal and you will fetal movements as well as away from fetal respiration actions.
