In the present review, we re\u2010evaluate an overview for the use of FPO and seven RCTs of FPO.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>We reviewed numerous previous reports on FPO and seven RCTs of intrapartum FPO. RCTs were conducted with the main outcome measure being a reduction in the cesarean section rate.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>The largest trial with 5341 entries failed to show any reduction. The negative result from this RCT may be explained by the use of a different cutoff value for fetal oxygen saturation compared to the other RCT; in addition, there were differences in the indications for cesarean section due to dystocia and in the definition of non\u2010reassuring fetal status (NRFS). An abnormal FPO value, defined as the fetal oxygen saturation value &lt;30% for at least 10\u2009min, is useful for making a diagnosis of fetal acidosis. A newly developed device, an examiner's finger\u2010mounted tissue oximetry, accurately measures tissue oxygen saturation while overcoming the drawbacks of FPO, such as infection risk and slipping off of the sensor during descent of the fetal head.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>FPO (including the new device) with fetal heart rate monitoring in selected
