Oxygen saturation monitoring system

A method of monitoring an oxygen saturation level of a user, the method comprising:

• receiving air pressure data from at least one pressure sensor about an environment proximate the at least one pressure sensor,
• receiving at least one measurement or determined input from at least one additional sensor distinct from the at least one pressure sensor, wherein the at least one additional sensor includes an oxygen sensor,
• determining an oxygen saturation level for the user in the environment based on the air pressure data, wherein the oxygen saturation level is determined using a physiology model having:
• an oxygen saturation level correspondence with air pressure data, and
• a sensitivity modifier for modifying a sensitivity of the physiology model in calculating the oxygen saturation level based on the at least one measurement or determined input from the at least one additional sensor deviating from a threshold,
• wherein the physiology model is configured to determine a preliminary oxygen saturation level, and further includes an additional sensor modifier configured to act as a threshold to trigger an adjustment to the determined preliminary oxygen saturation level, wherein:
• a) if the oxygen sensor indicates a low oxygen environment, the additional sensor modifier is configured to automatically modify the preliminary oxygen saturation level to indicate a hypoxia risk, or
• b) if the oxygen sensor indicates a high carbon dioxide level and/or high nitrogen level, the additional sensor modifier is configured to automatically modify the preliminary oxygen saturation level to indicate a hypoxia risk, and
• in response to determining the oxygen saturation level of the user has met one or more predetermined conditions, performing an action.

A monitoring system, comprising:

• at least one pressure sensor for detecting air pressure in an environment proximate the at least one pressure sensor;
• at least one additional sensor distinct from the at least one pressure sensor, wherein the at least one additional sensor includes a carbon monoxide sensor for providing a carbon monoxide measurement about the environment;
• and
• a processor coupled with the at least one pressure sensor and the at least one additional sensor, wherein the processor is programmed to
• receive air pressure data from the pressure sensor about the environment,
• determine an oxygen saturation level for a user in the environment based on the air pressure data, wherein the oxygen saturation level is determined using a physiology model having:
• an oxygen saturation level correspondence with air pressure data, and
• a sensitivity modifier for modifying a sensitivity of the physiology model in calculating the oxygen saturation level based on at least one measurement or determined input from the at least one additional sensor deviating from a threshold, and
• in response to determining the oxygen saturation level of the user has met one or more predetermined conditions, perform an action,
• wherein one of the predetermined conditions includes determining that the oxygen saturation level deviates from an oxygen saturation threshold, and wherein the processor is further configured to take a first corrective action,
• wherein if the carbon monoxide measurement indicates a carbon monoxide level exceeding a threshold, the processor is further configured to take a second, distinct corrective action, and
• wherein the carbon monoxide measurement enhances an accuracy of the determined oxygen saturation level.
