Baseline may be 100-110bpm By increasing fetal oxygen affinity After rupture of membranes and once the cervix is adequately dilated (>3cm), sampling a small amount of blood from the fetal scalp can be used to measure pH or lactate and thus detect acidosis. Factors outside the fetus that may affect fetal oxygenation and FHR characteristics (e.g., maternal, placental, or umbilical cord factors). A.
