Fetal Pulse Oximetry and Cesarean Delivery
New England Journal of Medicine, 2006Knowledge of fetal oxygen saturation, as an adjunct to electronic fetal monitoring, may be associated with a significant change in the rate of cesarean deliveries or the infant's condition at birth.We randomly assigned 5341 nulliparous women who were at term and in early labor to either "open" or "masked" fetal pulse oximetry.

Update on intrapartum fetal pulse oximetry
Australian and New Zealand Journal of Obstetrics and Gynaecology, 2002ABSTRACTThis article examines the current status of fetal pulse oximetry (FPO) as a means of intrapartum assessment of fetal wellbeing.FPO has been developed to a stage where it is a safe and accurate indicator of intrapartum fetal oxygenation. In general, sliding the FPO sensor along the examiner's fingers and through the cervix, to lie alongside the ...

Adjustable fetal phantom for pulse oximetry
Review of Scientific Instruments, 2009As the measuring head of a fetal pulse oximeter must be attached to the head of the fetus inside the mother’s uterus during labor, testing, and developing of fetal pulse oximeters in real environment have several difficulties. A fetal phantom could enable evaluation of pulse oximeters in a simulated environment without the restrictions and ...

Maternal position and fetal pulse oximetry
International Journal of Gynecology & Obstetrics, 1998In recent years fetal pulse oximetry has been under development as a possible complement to fetal heart rate monitoring, in predicting fetal well-being during labor [l]. This method enables a direct and continuous recording of fetal arterial oxygen saturation.

Obstetrics & Gynecology, 1999
To analyze labor outcomes in relation to masked fetal arterial oxyhemoglobin saturation values above or below 30%.Consenting gravidas with uncomplicated pregnancies at or beyond 36 weeks' gestation underwent continuous fetal pulse oximetry. Pregnancy outcomes were compared between two groups: women with fetuses with at least one epoch of arterial ...

Intrapartum fetal pulse oximetry
IEE Colloquium on Pulse Oximetry: A Critical Appraisal, 1996Several investigators have applied pulse oximetry technology to the fetus. Fetal oxygen saturation monitoring provides a direct, quantitative, and continuous measurement of the amount of oxygen present in fetal arterial blood. The fetus is a unique patient, both by being inaccessible to study and by having several mechanisms which enable it to survive ...

Intrapartum fetal pulse oximetry: present and future
International Journal of Gynecology & Obstetrics, 1995AbstractPulse oximetry is widely used to monitor the patient's well‐being in anesthetic and neonatal practice. As a result of recent technologic and theoretical advances, it has emerged as a clinical tool in intrapartum fetal monitoring. Oximeters record both pulse rate and arterial oxygen saturation of the fetus and they may be adapted to derive an ...

Factors Influencing Fetal Pulse Oximetry Performance
Journal of Clinical Monitoring and Computing, 2004Fetal pulse oximetry shares many problems with traditional pulse oximetry, but also poses unique challenges that may compromise accurate SpO2 determination and data availability. The purpose of this review is to characterize the factors that may influence fetal pulse oximetry and their relationship to sensor design.

Fetal pulse oximetry: a critical appraisal
Best Practice & Research Clinical Obstetrics & Gynaecology, 2004Despite 40 years of cumulative clinical experience, and a number of randomized clinical trials, electronic fetal heart rate monitoring is perceived by many obstetrical caregivers as a suboptimal method of intrapartum fetal assessment. Fetal pulse oximetry emerged 15 years ago as a promising new technology intended to improve assessment of fetal ...

Fetal monitoring by pulse oximetry and CTG
jpme, 1993To see if a pulse oximeter can monitor the fetus during labour we recruited 100 Caucasian women in normal uncomplicated labour. Our primary objective was to compare the predictive value of fetal pulse oximetry and cardiotocography using neonatal condition and cord blood acidaemia or hypoxaemia at birth as outcome variables.
