How to Approach Intrapartum Category II Tracings. Since its inception, many have questioned the utility of electronic fetal heart rate (FHR) monitoring. However, it arrived without the benefit of clear, standard nomenclature, leading to difficulty interpreting studies regarding its benefit. In 2008, the National Institute of Child Health and Human Development (NICHD) developed standard nomenclature for interpreting eFHR tracings. Understanding what drives the tracings is key to managing them. Category II FHR patterns are by far the most common and most diverse patterns, leading to broad variation in care. Presented here is an algorithm for standardization of management of category II FHR tracings, based on the pathophysiology of decelerations, that can be followed in any labor unit.
