Delivery Problem for Fetus

The goals of this observational study is to assess whether a new advanced wireless skin sensor vital sign monitoring system can effectively monitor the vital signs of healthy newborn infants (≥ 35 weeks gestational age). The main aims of this Study are to: 1. Assess feasibility 2. Evaluate safety 3. Determine accuracy of the wireless monitoring system, compared to the standard of care wired vital sign monitoring system, immediately after delivery and for the first 2h of age in the obstetrical center under unsupervised parents' care. The newborn infants participating in the Study will have both vital sign monitoring systems placed on their chest and limb. Their vital signs will be monitored for 2h consecutively.

Aims: Primary aim is to investigate outcomes of eutocic labor, evaluating intrapartum ultrasound parameters by AIDA method: Angle of progression (AoP), Asynclitism degree (AD), fetal head-symphysis distance (HSD), and midline angle (MLA). Secondary aim is to investigate outcomes of dystocic labor, evaluating intrapartum ultrasound parameters by AIDA method: Angle of progression (AoP), Asynclitism degree (AD), fetal head-symphysis distance (HSD), and midline angle (MLA). Tertiary aim is to investigate of neonatal outcomes of eutocic labor: Apgar scores at 1 min, Apgar scores at 5 min. Quaternary aim is to investigate of neonatal outcomes of dystocic labor: Apgar scores at 1 min, Apgar scores at 5 min.
