A method and communications module for recommending in what manner or mode a sensor and communications module of a subject monitoring system should communicate. A determination is made as to whether or not more than a predetermined number of wireless channels have a noise level below a certain threshold. If a positive determination is made, a wireless communication mode is recommended. If a negative determination is made, a wireless communication mode is not recommended.

A system for providing health services to a pregnant woman away from a medical facility is provided. The system may be configured to include first and second wearable devices to be worn by the pregnant woman. The first wearable device may be configured to collect a first set of health data of the pregnant woman and the second wearable device may be configured to collect a second set of health data of an unborn baby growing in the pregnant woman. Further, the system may be configured to include a mobile device configured to: communicate with the first and second wearable devices; collect the health data of the pregnant woman and her unborn baby; and communicate with a remote hospital personnel via one or more servers over a cloud-based network. The mobile device may be further configured to receive guidance or instructions from the remote hospital personnel in response to transmission of the health data of the pregnant woman and her unborn baby.

An apparatus for acquiring signals from a pregnant subject includes a flexible portion that is conformable to an abdomen of the subject. The flexible portion includes a plurality of signal acquisition points, each signal acquisition point comprising a contact adapted to electrically couple to a respective electrode and signal acquisition circuitry. The flexible portion includes a first linear section that is generally aligned along a first axis; and a second linear section extending from the first linear section, the second linear section being generally aligned along a second axis that is perpendicular to the first axis; wherein a first group of the signal acquisition points is located along the first axis and a second group of the signal acquisition points is located along the second axis.

Embodiments of the present disclosure describe methods, systems, and computer storage media for detecting sepsis in a maternal patient and causing for display a visual indicator of a graphical object. In some aspects sepsis may be detected based on a maternal patient's patient information and/or clinical diagnostic. Technologies described herein may be used to determine maternal-fetal sepsis and provide a graphical object of a patient's risk of the maternal-fetal sepsis. The visual indicator and graphical object may be identifiable to a clinician as a warning of a risk for maternal-fetal sepsis. In this way, maternal-fetal sepsis may be identified and a graphical object may be generated, facilitating timely treatment and early diagnosis of maternal-fetal sepsis.

Methods to compute gestational age and time to delivery utilizing temporal alignment methods and applications thereof are described. Generally, systems utilize analyte measurements collected at one or more time points to determine a gestational age and time to delivery, which can be used as a basis to perform interventions and treat individuals. Computational models trained utilizing temporal alignment of analyte measurements can be used to determine gestational age and time to delivery.

A maternal and fetal monitoring system includes a detection probe configured to conduct physiological measurements on a maternal abdomen, the detection probe comprising a probe housing configured to be attached to the maternal abdomen, and a plurality of electrodes integrated into the probe housing and configured to acquire biopotential physiological data from the maternal abdomen. At least one controller is configured to calculate fetal heart rate (fHR) values, maternal heart rate (mHR) values, and/or uterine activity (UA) values based on both the physiological measurements and the biopotential physiological data, and a graphical display communicatively connected to the controller to receives and visually presents the calculated fHR values, mHR values, and/or UA values.

Communication of parent physiological data to an infant may include a first interface device which includes a sensor to record physiological data associated with a heartbeat of a parent, a processor to receive the physiological data from the sensor, and a transceiver; a server which receives the physiological data from the transceiver, accesses an instance of the physiological data from a replay storage location during a loss of communication, assigns a unique identifier, processes the physiological data, modifies the physiological data to be within an allowable threshold or accesses physiological data within the allowable threshold when the physiological data is outside an allowable threshold, filters the physiological data to apply an effect, and transmits the physiological data based on the unique identifier; and a second interface device which includes a transceiver to receive the physiological data and a communication element to communicate the physiological data to the infant.

A decision support tool is provided for predicting the neonatal vitality scores of a fetus during delivery, the scores being an indicator of future health for the infant anticipated to be born within a future time interval, measured as time to birth. The predicted neonatal vitality score is determined from measurements of physiological variables monitored during labor, such as uterine activity and fetal heart rate. Fetal heart rate variability and patterns may be detected and computed using the monitored physiological variables, and neonatal vitality scores may be predicted based, at least in part, on the variability metrics and fetal heart rate patterns. Scores may be predicted for different delivery methods, such as vaginal delivery or cesarean delivery, for different time-to-birth intervals. In this way, these scores may be used for decision support for care plans during labor, such as increased monitoring and/or modifying the delivery type.

Fracture-induced composite sensors and methods of their fabrication are disclosed. The sensors can be used as strain sensors, piezo-resistive sensors, piezo-capacitive sensors, and non-contact displacement wearable sensors.

A system for assessing and monitoring a fetal electrocardiogram (ECG) and heart rate in a pregnant mother comprises wearable mechanical-electronic sensors, e.g., embedded in a wrist or arm band, which can measure mechanical pulse signals from the mother, and an abdomen patch which can measure the combined ECG signals of the fetus and mother. In another embodiment, the sensors in the wrist or arm band measure the combined fetal/maternal ECG signals, and the mother's mechanical pulse signals. By signal processing and gating out the maternal ECG signals as correlated with the mechanical maternal pulse signals, the fetal ECG and heart rate can be measured and monitored. These measurements may be displayed on the wrist or arm band device, or wirelessly through a remote device, mobile phone or computer. Sensors in the abdominal patch may also measure uterine electromyogram, uterine contractions, and fetal movements, to be correlated with the fetal ECG.
