This fetal monitoring method allows increased mobility of the mother

This fetal monitoring method allows the mother to use water-based pain management
Auscultation of FHR
This fetal monitoring method provides a more natural atmosphere
Auscultation of FHR
This fetal monitoring method can only assess FHR and uterine activity for a small part of labor
