Intrapartum fetal oxygen saturation monitoring in a busy labour ward
1Department of Obstetrics and Gynaecology, National University of Singapore, National University Hospital, Singapore.
Objective:
To measure the ease of use of a fetal pulse oximeter in a busy labour ward.
Design:
Descriptive study in the Labour Ward, National University Hospital, Singapore, involving 145 labouring women with singleton pregnancies, and fetuses in cephalic presentation, with cervical dilatation >2 cm and amniotic membranes ruptured.
Results:
Placement was comfortable. Oxygen saturation (SpO2) readings were obtained in 127 women (87.5%). Adequate readings were obtained a median of 69% of the time the transducer was in situ. SpO2 values in the last 10 min prior to delivery correlated poorly with parameters of neonatal outcome.
Conclusion:
The Nellcor N-400 fetal pulse oximeter and FS14 fetal sensor is a feasible method of intrapartum fetal monitoring in a busy labour ward and is acceptable to labouring women.

Guidelines For Measuring Vital Signs
Before taking a patient's vital signs, a nurse would consider and assess the patient's comfort level and ensure appropriate equipment is available.

Conversely, an irregular pulse pattern is termed dysrhythmia, stemming from disruptions in cardiac muscle...

Fetal Circulation
Two umbilical arteries transport blood from the fetus to the placenta. At the placenta, the blood absorbs oxygen and nutrients while simultaneously eliminating waste products. This oxygen-enriched and nutrient-rich blood then returns to the fetus through one...
