The book reviews new technologies and devices aimed to improve labor management and outcomes. These diverge between looking at a better way to use fetal heart rate monitors (that are used in 90% of labours); using new monitors to detect the 1% ofbabies that are damaged in labour and account for 99% of the medico-legal costs in labor; and early detection of non-progressive labors that complicate 30-50% of labours. This is the only book about all these technologies from the perspectives of new devices and technologies in labor.
