NONA Garment Project: Noninvasive Observation of Natal Activity
Principal Investigator: AARON ROOD
Abstract: Named NONA, after the Roman God of pregnancy this innovative system will monitor the expectant mother to mitigate the risk to mother and child during birth. During this Phase I project, Orbital Research Inc. (Cleveland, Ohio), with their partners at MIT, Tufts-New England Medical Center and E-Trolz, Inc., intends to build, then test a novel fetal electrocardiograph (FECG) monitoring system. The fetal ECG harness device will be a large sensor array that can be applied in a convenient and rapid manner to an expectant mother. The garment-based sensor array will allow sensors to be placed in anterior, posterior and lateral positions on the mother in a single step. The garment will leverage the Orbital Research dry, ECG recording electrodes1, the E-Trolz embedded platform, and signal processing expertise from the laboratory for computational physiology at MIT. The proposed non-invasive fetal monitor will reliably acquire fetal ECG signals, and identify characteristic ECG patterns that predict impending fetal injury caused by inflammatory, hypoxic, or ischemic insults. During this Phase I project, Orbital Research Inc (Cleveland, Ohio), with their partners at the Massachusetts Institute of Technology, Tufts Medical Center, and E-Trolz, Inc., will build, test and demonstrate the feasibility of a novel fetal electrocardiograph (FECG) monitoring system. The ultimate program goal (after completion of Phase II) is to produce a reliable, inexpensive, non-invasive system for fetal monitoring during pregnancy and labor. The information gained from this system will mitigate risk to the mother and fetus during delivery which will dramatically improve clinical outcomes especially from high risk deliveries. 1 FDA cleared. The ORI F6T Dry ECG Electrode is intended for use in all ECG monitoring applications where standard ECG monitoring electrodes are used. The F6T Electrode can be used in short term and long term (up to 2 days) ECG monitoring. PUBLIC HEALTH RELEVANCE: The ultimate goals of this NONA (Non-Invasive Observation of Natal Activity) program are: 1) To develop a reliable, inexpensive, non-invasive system for fetal monitoring during pregnancy and labor, and 2) to identify FECG characteristics that predict adverse events during labor and the immediate postpartum period. The Phase I program outcome will be the demonstration of the feasibility of the complete system - garment- sensors, hardware, and algorithms to identify health risk to the child during childbirth. Upon successful completion of the Phase I program, the Orbital Team will have: " fabricated several disposable garments with integrated sensors, " captured data from a set of women in the birthing center at TUFTS- New England Medical Center, and " demonstrated fetal heart rate and components of FECG can be identified accurately using Kalman Filtering relative to the available truth markers collected via the scalp sensor.
