Abstract
A thermal stress monitoring system includes at least one wearable sensor adapted to be placed on a human subject. The at least one wearable sensor is sensitive to changes in spontaneous blood volume oscillations and is configured to generate output signals. A processing subsystem receives the output signals and measures baseline spontaneous blood volume oscillations at a time when the user is not exposed to a thermal stress environment and subsequently measures the exposed spontaneous blood volume oscillations at a time when the user is exposed to the thermal stress environment and determines a thermal stress injury based on changes in the measured exposed spontaneous blood volume oscillations from the measured baseline spontaneous blood volume oscillations.

- and
- a processing subsystem configured to receive the output signals and configured to measure baseline spontaneous blood volume oscillations at a time when the user is not exposed to a thermal stress environment and subsequently measure the exposed spontaneous blood volume oscillations at a time when the user is exposed to the thermal stress environment and determine a thermal stress injury based on changes in the measured exposed spontaneous blood volume oscillations from the measured baseline spontaneous blood volume oscillations.
A thermal stress monitoring system, the system comprising:
- at least one peripheral wearable sensor adapted to be placed on a peripheral area of a user, the peripheral wearable sensor including:
- at least one peripheral light source configured to emit light at one or more predetermined wavelengths associated with spontaneous blood volume oscillations into tissue of a human subject, and

- at least one baseline wearable sensor adapted to be placed on a core area of a user, the baseline wearable sensor including:
- at least one baseline light source configured to emit light at one or more predetermined wavelengths associated with spontaneous blood volume oscillations into tissue of a human subject, and
- at least one baseline detector configured to detect reflected light at the one or more predetermined wavelengths associated with the spontaneous blood volume oscillations and generate baseline output signals;
- and
- a processing subsystem configured to receive the baseline output signals and configured to measure the baseline spontaneous blood volume oscillations and configured to receive the peripheral output signals and measure the peripheral spontaneous blood volume oscillations at a time when the user is exposed to a thermal stress environment and determine a thermal stress injury based on changes in the measured peripheral blood volume oscillations from the measured baseline spontaneous blood volume oscillations.
A system for detecting at least one condition that restricts perfusion of peripheral tissue, the system comprising:

- and
- a processing subsystem configured to receive the output signals and configured to measure baseline spontaneous blood volume oscillations at a time when the user does not have at least one condition that restricts perfusion of peripheral tissue and subsequently measure conditional spontaneous blood volume oscillations at a time when the user has at least one condition that restricts perfusion of peripheral tissue and determine at least one condition that restricts perfusion of peripheral tissue based on changes in the measured conditional spontaneous blood volume oscillations from the baseline spontaneous blood volume oscillations.
A thermal stress monitoring method, the method comprising:
- measuring changes in spontaneous blood volume oscillations and generating output signals;
- responding to the output signals;
- and
- measuring baseline spontaneous blood volume oscillations at a time when the user is not exposed to a thermal stress environment and subsequently measuring the exposed spontaneous blood volume oscillations at a time when the user is exposed to the thermal stress environment and determining a thermal stress injury based on changes in the measured exposed spontaneous blood volume oscillations from the measured baseline spontaneous blood volume oscillations.
