Fetal pulse oximetry and other monitoring modalities - Future directions

Although in the beginning phase of its use, the application of fetal oximet ry in high-risk obstetrics is predicted to increase. Even at its early clin ical application, patient data have shown that fetal oximetry has the excel lent potential to be used with other fetal monitoring modalities to further characterize the metabolic state of the fetus, especially during labor. Si milar to other monitoring modalities, the clinicians also need to be aware of its limitations.
