What is the normal oxygen saturation range for fetal pulse oximetry?

The normal oxygen saturation range for fetal pulse oximetry is typically between 30% to 65%. This range reflects the physiological differences between maternal and fetal circulation. In fetuses, normal oxygen saturation levels are significantly lower than those seen in adults due to various factors, including placental oxygen transfer efficiency and fetal hemoglobin characteristics.

Fetal pulse oximetry is a non-invasive monitoring technique used during labor and delivery to assess a fetus's oxygenation status, particularly when there are concerns about the fetal heart rate or overall well-being. Values within this range indicate that the fetus is receiving adequate oxygenation and there are no immediate concerns regarding hypoxia.

Understanding this range is crucial for nursing professionals involved in the care of expectant mothers, as it helps them interpret fetal well-being during labor and make informed decisions regarding interventions if necessary.
