Sensor-based systems and methods for monitoring maternal position and other parameters
First Claim
1. A monitoring system for monitoring for an aortocaval compression condition, the monitoring system comprising:
- one or more sensors configured to be secured directly or indirectly to the user and configured to generate sensor signals;
a processor;
computer instructions stored in non-transitory computer-readable medium and executable by the processor to;
receive the sensor signals generated by the one or more sensors;
determine a physical orientation of the user based on the received sensor signals;
determine heart rate variability (HRV) data based on the received sensor signals, the heart rate variability data indicating at least one of (a) a heart rate variability of the user or (b) a heart rate variability of the fetus;
identify an aortocaval compression condition based at least on the determined physical orientation of the user and the determined HRV data; and
automatically generate and transmit an alert signal in response to identifying the aortocaval compression condition; and
an alert mechanism configured to receive the alert signal and output an alert to the user.

Abstract
Sensor-based systems, devices, and methods are disclosed for monitoring for an aortocaval compression condition in a pregnant woman. A sensor device may be secured directly or indirectly to the woman, which may collect various sensor data related to the woman and/or the fetus. The device may determine a physical orientation of the woman (e.g., upright and/or lateral tilt angles of the woman) and/or biometric parameter(s) of the woman and/or fetus based on the collected sensor data, identify an aortocaval compression condition based on the determined orientation of the woman and/or biometric parameter(s) of the woman and/or fetus, and generate a repositioning alert via an alert mechanism. The disclosed concepts may be implemented, for example, as a personal home-use device, or as a broader system in a hospital or other medical facility, e.g., for monitoring and displaying aortocaval compression related information for multiple patients and/or facilitating patient turn protocols.
