The EUM (electrical uterine myography) (OB Tools, Israel) was tested and found to be reliable as a non-invasive method for evaluating uterine contractions and the fetal heart rate. It is safe and effective in monitoring uterine contractions. The investigators propose to perform a study to validate the accuracy and clinical usefulness of the EUM device by simultaneously monitoring obese patients with current method of external tocodynamometry with the EUM device. Providers will be blinded to the results of the EUM device. Caregivers will continue care as per current guidelines using the information obtained from the current monitoring methods. Information obtained from the EUM devices will not be used to determine the clinical course of action.
Purpose: The investigators propose to perform a study to validate the accuracy and clinical usefulness of the EUM device by comparing it with simultaneous use of current methods (external tocodynamometry) among obese patients. Objective: Compare the interpretability of the contractions recorded using the EUM device vs. those obtained from external tocodynamometer among obese pregnant women.
Study Type
OBSERVATIONAL
Enrollment
48
This study involves monitoring one group of pregnant women for contractions simultaneously using two different devices to determine if one is superior: the usual tocodynamometer commonly used. Women are simultaneously monitored with both devices.

Continuity in Readings of Contractions
Continuity in readings of contractions, as measured in the number of minutes without a readable tracing in a sample tracing, between the novel EUM device and the external tocodynamometer (standard care) were assessed in pregnant preterm patients. An uninterpretable tracing was defined as any contraction, or any period of contractions, with unclear/uninterpretable baseline, peak onset/timing, height/peak, or duration of contraction.
Time frame: within 4 hours of device application
Continuity in Readings of Fetal Heart Rate
Continuity in Fetal Heart rate readings, as measured by the number of minutes without a readable tracing in a sample tracing between the novel EUM/EMG device and the external tocodynamometer (standard care) will be assessed in pregnant preterm patients. An uninterpretable tracing is defined as any period of fetal heart rate tracing with unclear/uninterpretable baseline, variability, onset/timing, peak, frequency, or duration of accelerations/decelerations
Time frame: within 4 hours of device application
