Abstract: Described are various embodiments of a system and method for adaptive user experience cycle profiling under anomalous environmental respiratory conditions, such as in hyperbaric or hypobaric environments. In one embodiment, the system comprises an environmental sensor operable to monitor a respiratory environment parameter representative of the anomalous environmental respiratory condition that defines the experience cycle; and a physiological sensor operable to concurrently monitor a physiological parameter representative of the user's cumulative physiological response to the anomalous environmental respiratory condition over time during the experience cycle.

Abstract: Described herein are various embodiments of systems and devices operable to detect individual oxygen delivery events at a user body region which are associated with external oxygen boluses administered to a user. Such devices and system may be useful, for example, in assessing the efficacy of cardiopulmonary resuscitation (CPR) or intubation.
