Summary

Healthy newborns require over 5 minutes to achieve normal oxygen saturation (SpO2) when breathing room air. Cesarean-delivered infants had lower SpO2 and took longer to stabilize than vaginally-delivered infants.

Area of Science:

  • Neonatal physiology
  • Pediatric respiratory health

Background:

  • Oxygen saturation (SpO2) monitoring is crucial for assessing newborn adaptation.
  • Understanding normal SpO2 transition is vital for identifying potential complications.

Purpose of the Study:

  • To document SpO2 changes in healthy newborns during the initial 10 minutes of life.
  • To compare SpO2 trends between infants born via different delivery modes.

Main Methods:

  • Observational study design.
  • Continuous preductal SpO2 recordings in infants >= 35 weeks gestation.
  • Exclusion of infants requiring supplemental oxygen.

Main Results:

  • 115 infants analyzed; Cesarean delivery associated with 3% lower SpO2 (P=.01).

  • Cesarean infants took longer to reach stable SpO2 >= 85% (RR 1.79, P=.04).
  • At 5 minutes, median SpO2 was 87% (vaginal) vs. 81% (cesarean); 90% not reached until 8 minutes.

    • Conclusions:

    • Normal postnatal oxygen saturation transition exceeds 5 minutes in healthy, room-air breathing newborns.
    • Delivery mode impacts early SpO2 stabilization in healthy neonates.
