Fetal oxygen saturation by pulse oximetry (SpO2) during labor in healthy fetuses showed wide but stable ranges, consistently above 30%. These SpO2 values did not significantly change with cervical dilation or approach of delivery.

Area of Science:

  • Obstetrics and Gynecology
  • Fetal Monitoring
  • Neonatal Outcomes

Background:

  • Fetal pulse oximetry (SpO2) is a method for assessing fetal well-being during labor.
  • Understanding normal SpO2 ranges is crucial for interpreting fetal status.

Purpose of the Study:

  • To determine fetal oxygen saturation by pulse oximetry (SpO2) values at various cervical dilation stages during labor.
  • To establish SpO2 reference ranges in fetuses with normal neonatal outcomes.

Main Methods:

  • Continuous fetal monitoring using cardiotocography and fetal pulse oximetry (Nellcor N-400, FS-14) in 145 women at term.
  • Inclusion criteria: established labor, ruptured membranes, cervical dilation ≥2 cm, normal neonatal outcome (Apgar ≥7, birthweight ≥2500g, cord pH ≥7.15, no NICU admission).

Main Results:

  • A wide range of SpO2 values was observed in fetuses with normal outcomes.
  • Mean SpO2 averaged 50% ±10% during the first stage of labor, with lower values above 30%.
  • No significant differences in SpO2 were found across different cervical dilatations or in the final minutes before delivery.

Conclusions:

  • The normal range of fetal SpO2 during labor is wide but remains above 30%.
  • No discernible trend in SpO2 values was identified in relation to labor progression in this cohort.
  • Fetal pulse oximetry values in healthy fetuses exhibit considerable variability without a clear pattern during normal labor.
