Abstract

The objectives of the study were to assess the ability of a fetal pulse oximeter to measure the fetal oxygen saturation (SPO₂) continuously during labor and to assess the correlation between readings of fetal pulse oximetry and cord blood gases at birth. The Nellcor N-400 Fetal Oximeter was used in 62 women prospectively. The mean SPO₂ was unchanged at the different stages of normal labor: 53.3 ± 9.1 to 50.1 ± 11.8% (n = 50). The SPO₂ recorded during the pushing phase of stage II (n = 40) was correlated significantly with umbilical cord arterial pH (r = 0.55; p = 0.0002), venous pH (r = 0.63; p = 0.0001), venous PCO₂ (r = 0.47; p = 0.002) and venous PO₂ (r = 0.39; p = 0.01). SPO₂ was also correlated with scalp pH (r = 0.52; p
