Abstract: A system and method to reduce and manage patient monitoring alarms utilizing a longitudinal, analytics-based analysis. The method includes a patient monitoring system receiving monitored data from one or more patients and generating threshold alerts for each patient based upon alert thresholds in real time. The number of alert thresholds that occur over an analysis period is compared to an enhanced alert threshold. If the number and frequency of the threshold alerts violates an enhanced alert threshold, an enhanced indicator is generated on a display for the patient being monitored. The enhanced indicator can be generated for any one or multiple monitored data types from the patient and enhances the longitudinal monitoring of the patient over an analysis period. The enhanced indicator provides a visual indicator to the monitoring technician of the occurrence of a higher than desired number of threshold alerts over the analysis period.

Abstract: An infant care device that selectively controls the amount of visible light that is transmitted into the interior of an enclosure while allowing the transmission of light within certain wavelengths. The infant care device includes an enclosure that includes light dimmable technology that adjusts the transparency of the enclosure based upon control signals from a primary controller. The primary controller is able to cycle between day/night on a manual or automatic basis to selectively control the amount of light that reaches the infant patient. The light dimming technology used on the enclosure allows the transmission of light within a phototherapy wavelength spectrum. The controller thus controls the transparency of the enclosure to at least partially reduce or increase the light reaching the infant while allowing phototherapy.

Abstract: A method of monitoring depth of muscle relaxation of a patient includes applying a series of stimulations to a nerve of a patient and measuring muscle responses thereto. A maximal stimulus current, a supramaximal stimulus current, and/or a submaximal stimulus current are determined based on the muscle responses, wherein the maximal stimulus current is a current at which a maximal muscle response is produced from stimulating the nerve, the supramaximal stimulus current is greater than or equal to the maximal stimulus current, and the submaximal stimulus current is less than the maximal stimulus current. A first set of stimulations are applied to the nerve of the patient. Either the supramaximal stimulus current or the submaximal stimulus current are then selected for a subsequent series of stimulations based on the measured muscle responses to the first series of stimulations, and the subsequent series of stimulations are performed accordingly to monitor the patient's depth of muscle relation.
