Accuracy and Reliability of Novii: Fetal Heart Rate (FHR), Maternal Heart Rate (MHR) and Uterine Contraction (UA) Compared With Doppler, Scalp Fetal Scalp Electrode (FSE), Tocodynamometer (TOCO) and Intra Uterine Pressure Catheter (IUPC)
Accuracy and Reliability of a New Intrapartum Fetal Heart Rate, Maternal Heart Rate, and Uterine Contraction Monitoring Method Compared With Food and Drug Administration (FDA) Approved Techniques.

Detailed Description
The study is being done to test the performance of a Novii Wireless Patch System for following the baby's and mother's heart rates and uterine contractions during labor. We want to find out if the new monitor works as well as other types of monitors that are usually used: Doppler Fetal Heart Rate (FHR), Scalp FHR, Tocodynamometer (TOCO) and Intra Uterine Pressure Catheter (IUPC).
80 patients will be monitored during the study.

Description
Inclusion Criteria:
A woman will be considered for inclusion in the study if she fulfills all of the following criteria:
- She has a term or near term (≥36 completed weeks) singleton gestation in a cephalic presentation and has been admitted to the Labor and Delivery Unit .
- She is in the latent phase of spontaneous labor, or has been admitted for induction of labor.
- She has given her informed consent to participate as a subject.
- She has none of the exclusion criteria.
Exclusion Criteria:
- Known major fetal malformation or chromosome abnormality.
- Multiple gestation
- A condition for which cesarean will likely be carried out shortly.
- Subject plans not to have electronic fetal monitoring.
- Involvement in another clinical trial currently or previously in this pregnancy that, in the investigator's opinion, would affect the conduct of this study.
- Medical or obstetric problem that would preclude the use of abdominal electrodes (e.g., skin eruptions, history of sensitivity to adhesives).
- Parturient is under age 18.
- Medical or obstetric problem that in investigator's opinion would make the patient incapable of taking part in the study.
- Inability to understand the consent information due to medical illness or diminished intellectual capacity, or insurmountable language barrier.
- Potential for coercion, e.g. Medical Center employees, prisoners.

Term Patients
Approximately 80 pregnant women monitored in labor between 37 and 42 weeks' gestation will be necessary to complete the study. Subjects will have a singleton >37 week pregnancy. Subjects will be recruited for the study in the following groups : At least 10 patients with Body Mass Index (BMI) < 30 kg/m2 At least 10 patients with BMI 30-34.9 kg/m2 At least 10 patients with BMI ≥ 35 kg/m2 |
The Monica Novii Wireless Patch System is a transabdominal fetal/maternal recorder that provides fetal heart rate, maternal heart rate and maternal uterine activity contractions.

What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Fetal Heart Rate (FHR) Positive Percentage Agreement (PPA)
Time Frame: through study completion, an average of 1 year
|
PPA(%)=(a/(a+C))x100, where "a" represents the number of 2 second epochs when the Novii FHR is within +/-10% of the predicate device FHR for each 2 second epoch, and "c" are the number of 2 second epochs when the Novii FHR is not within +/- 10% of the predicate device FHR or is absent.
|
through study completion, an average of 1 year
|
Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Mean Percentage FHR Equivalence
Time Frame: through study completion, an average of 1 year
|
The 2 second output FHR data when both the predicate and Novii devices are reporting a value will be considered.
In this case for each 2 second epoch the FHR value from the Novii device is divided by the predicate device FHR value to create a "FHR ratio".
|
through study completion, an average of 1 year
|
Uterine Activity (UA) Sensitivity (from Individual Contractions)
Time Frame: through study completion, an average of 1 year
|
The Sensitivity of the Novii System against the predicate device is determined from the "individual contraction "detection as follows: Sensitivity(%)=(x/(x+z))x100 Where: "x" is the total number of "individual contractions" detected by both the devices "z" is the total number of "individual contractions" detected by the predicate device only |
through study completion, an average of 1 year
|
Uterine activity Positive Percentage Agreement (from Interpretable Data)
Time Frame: through study completion, an average of 1 year
|
The positive percentage agreement (PPA) is determined from the interpretable and uninterpretable data as follows: PPA(%)=(a/(a+c))x100 Where: "a" is the number of minutes when both devices UA are "interpretable" at the same time "c" is the number of minutes when the predicate device UA is "interpretable" but the Novii system UA is "un-interpretable". |
through study completion, an average of 1 year
|
Maternal Heart Rate (MHR) Positive Percentage Agreement (PPA)
Time Frame: through study completion, an average of 1 year
|
PPA(%)=(a/(a+C))x100, where "a" represents the number of 2 second epochs when the Novii MHR is within +/-10% of the predicate device MHR for each 2 second epoch, and "c" are the number of 2 second epochs when the Novii MHR is not within +/- 10% of the predicate device MHR or is absent.
|
through study completion, an average of 1 year
|
Mean Percentage MHR Equivalence
Time Frame: through study completion, an average of 1 year
|
The 2 second output MHR data when both the predicate and Novii devices are reporting a value will be considered.
In this case for each 2 second epoch the MHR value from the Novii device is divided by the predicate device MHR value to create a "MHR ratio".
|
through study completion, an average of 1 year
