Energy conversion monitoring devices, systems, and methods

Abstract

Persons with sleep disordered breathing (SDB) may, or may not, recognize that they have symptoms of SDB, and/or that they may be at-risk of, or suffering certain health problems associated with SDB, including death. The disclosed Energy Conversion Monitor (ECM) sensor, when embodied, for example, in a wearable upper-armband format, has been demonstrated to be more sensitive and responsive than pulse oximetry monitoring of blood oxygen saturation as an indication of hypoxic stress induced by SDB, and is compatible with: (1) inclusion in sleep laboratory polysomnograph (PSG) testing instrumentation, (2) home-based diagnostic testing for SDB, (3) control of home-use airway therapy devices, (4) continuous remote surveillance and refinement of airway therapy, and (5) spot-check and continuous surveillance of sleep quality in the general population. The disclosed ECM also provides new measurements of physiologic stress during and following exercise. When applied during initial care of premature newborn infants, it offers improved therapeutic guidance during their transition from their limited in utero oxygen supply conditions, to the increased oxygen availability from breathing air. When applied during resuscitation of persons suffering from hypoxia and during reperfusion of ischemic tissue, such as during treatment of ischemic stroke, or ischemic heart attack, the ECM sensor can provide objective guidance regarding the safe and effective resupply of oxygen to the hypoxia-adapted tissue to help reduce or prevent microvascular occlusion and cellular injury. As a continuously worn physiologic surveillance monitor, the ECM offers the potential of early detection of sepsis. For the elderly and infirm, the ECM offers a convenient and comfortable means of continuously assessing variations in status while awake and asleep.

[0001] cross reference [0002] This application requires September 16, 2019 The serial number submitted is 16 / 572106 priority of the U.S. application for which the U.S. application claims September 18, 2018 The name of the submission is " Sleep Disordered Breathing Monitors, Systems and Methods "U.S. Provisional Application No. 62 / 732876 , the U.S. Provisional Application is hereby incorporated by reference in its entirety. technical field [0003] Sensor devices, systems and methods for monitoring oxygen-related physiological functions of a human body are disclosed. In particular, the sensor system of the present disclosure provides real-time and near real-time non-invasive monitoring of oxygen demand versus oxygen supply at the cellular level. The systems, devices and methods monitor the full spectrum of oxygen-based physiology from "cellular hypoxia" (cellular hypoxia) through "just right" (aerobic metabolism) to "cellular hyperxia" (cellular hyperxia).
