Visually apparent decrease in FHR below the baseline Decrease in FHR from the baseline that is 15 beats per minute or more, lasting 2 minutes or more but less than 10 minutes in duration. Term Fetal Heart Rate Variability. The purpose is to assess for fetal distress and hypoxia, as well as to ascertain the stability of the cervix. J Matern Fetal Neonatal Med. Description This introductory course is designed to assist individuals developing competency in fetal heart monitoring. So, that is where we start from in terms of litigating these cases from a plaintiff perspective. The management of such abnormalities must take into consideration several factors, including the presence of fetal tachycardia or bradycardia, duration of abnormalities, and the expected time of delivery.
There are likely many reasons for this decrease, including physician experience, difficulty in obtaining and processing and adequate sample in a short amount of time, and the need for routine maintenance and calibration of laboratory equipment that may be used infrequently. This can be accomplished via periodic auscultation or by intermittent or continuous electronic means. This test can be performed as early as 24 weeks. For example, some patients with non-reassuring fetal heart rate patterns which developed in the second stage of labor could have gone on to deliver vaginally during the occasionally time-consuming minutes that it took to insert the device.

The benefits of fetal transfusion in the treatment of Binduced hydrops are Although many interpretative systems exist for EFM tracings, the selected system must be evidence based, simple, and applicable to clinical practice.
