Alert management for physiological event detection

Systems, devices, and methods for managing alerts associated with a target physiological event such as a worsening heart failure event are described. A system may detect one or more alert onsets using an onset threshold, and one or more corresponding alert terminations using a reset threshold. Alerts may be issued corresponding to the detected alert onsets and alert terminations. The system may compare the alerts to a specified alert characteristic, and iteratively adjust the onset or reset threshold until the alerts corresponding to the adjusted onset or reset threshold satisfy the specified alert characteristic. The adjusted onset and reset thresholds may be presented to a user or a process for detecting the target physiological event.

Patient video monitoring systems and methods having detection algorithm recovery from changes in illumination

Various embodiments concern video patient monitoring with detection zones. Various embodiments can comprise a camera, a user interface, and a computing system. The computing system can be configured to perform various steps based on reception of a frame from the camera, including: calculate a background luminance of the frame; monitor for a luminance change of a zone as compared to one or more previous frames, the luminance change indicative of patient motion in the zone; and compare the background luminance to an aggregate background luminance, the aggregate background luminance based on the plurality of frames. If the background luminance changed by more than a predetermined amount, then the aggregate background luminance can be set to the background luminance, luminance information of the previous frames can be disregarded, and motion detection can be disregarded.

Apparatus and method to suppress or prevent false alarms in an esophageal temperature probe and feeding tube

A method of preventing or suppressing a false alarm during administration of food or medicine to a human or animal through a feeding tube having one or more sensors that generate a signal, comprises analyzing the signals to determine whether food or medicine is being administered and, if it is determined that food or medicine is present, preventing or suppressing an alarm. In a further step, the time and length of administration of food or medicine is recorded. When the feeding tube has at least two temperature sensors, differences in the temperatures recorded for the different temperature sensors indicate that food or medicine was administered. In a case where there is only one temperature sensor, the rate and extent of any temperature change of temperatures recorded from that temperature sensor are compared to an algorithm to determine whether feeding occurred. If the feeding tube has two or more electrodes that sense a change in impedance (galvanic or non-galvanic), that change indicates whether food or medicine is being administered. The signals are analyzed by a processor, monitor, or controller that generates an alarm signal.
