1. A breathing mask with a sensor system for use with a physiologic monitoring and support system for identifying or predicting dangerous health conditions comprising:
a breathing mask with a breathing gas input and an exhalation output, the breathing gas input adapted to allow inhaled breathing gas to enter the mask, the exhalation output adapted to allow exhaled breath to exit the mask, and the inhaled breathing gas comprising a known inspired amount of oxygen;
at least one check-valve attached to or integrated into the breathing mask, the check-valve adapted to separate the breathing gas input and exhalation output to prevent inhaled and exhaled gases from mixing within the mask;
at least one sensor attached to or integrated into the breathing mask adapted to measure an exhalation output of a subject and the at least one sensor having a signal related to partial pressure of oxygen from exhaled breath of the subject; and
a processor configured to receive the signal and calculate a standard oxygen absorption value per breath based at least in part on the signal related to the partial pressure of oxygen from exhaled breath of the subject and at least in part on the known inspired amount of oxygen.
