Abstract: A cardiopulmonary resuscitation (CPR) cerebral monitoring device including a measurement probe having one or more optical emitters, and one or more optical detectors, and including an optical instrument having an optical source, and an optical detector. Also included is a controller configured to control the optical instrument to emit multi-spectral light through the one or more optical emitters to illuminate a tissue, control the optical detector to detect multi-spectral light emitted from the illuminated tissue, compare the emitted multi-spectral light to the detected multi-spectral light, compute a plurality of cerebral tissue parameters based on the comparison, determine CPR procedures based on the plurality of cerebral tissue parameters, and control a user output device to instruct a user to perform the CPR procedures, and/or control an automated CPR device to perform the CPR procedures.

Abstract: A system for playing audio/video includes a set of triggering objects. Each triggering object has a respective computer readable image. The system further includes a camera for capturing images within a zone of interactivity, an audiovisual output device, and a set of stored responses. Each response corresponds to at least one of the triggering objects. The system further includes a computing device connected to the camera and to the audiovisual output device. The computing device is configured to i) determine when a first one of the triggering objects and/or a second one of the triggering objects is within the zone of interactivity; ii) identify a first pre-produced audiovisual response corresponding to the first one of the triggering objects and identify a second pre-produced audiovisual response corresponding to the second one of the triggering objects; and iv) concatenate the first pre-produced audiovisual response and the second pre-produced audiovisual response.
