Resuscitative measures for category II and/or III fetal heart rate tracings

These measures are aimed at improving uteroplacental blood flow, placentofetal blood flow, and fetal oxygenation. It is important to evaluate for the underlying cause(s) of the fetal heart rate pattern, as urgent delivery is necessary in some acute settings, such as uterine rupture, cord prolapse, or severe abruption. Physician judgment plays an important role in terms of assessing the probable cause, choosing the appropriate interventions for the specific patient setting, assessing the response to those interventions, and timing of cesarean delivery if the pattern persists. For example, discontinuing uterotonic drugs and administering a tocolytic agent is particularly important in patients with tachysystole. Multiple interventions are generally applied simultaneously.
