1. A method, of monitoring emergency personnel, comprising:
- acquiring values of levels of carboxyhemoglobin in a person'"'"'s blood during a sampling period, the person being in a region near or at a source of carbon monoxide;
recording the values on machine-readable media;
determining a regression function for the values with respect to time;
determining at least one of an attribute of the function and a future value of a carboxyhemoglobin level in the person'"'"'s blood, the future value being determined by extrapolation of the function; and
providing a user with safety information based on the at least one of the attribute of the function and the future value;
wherein the safety information comprises at least one of visible, tactile, and audible information; and
wherein the safety information comprises at least one of a time of remaining safety in the region, a warning to exit the region, an indication of continuing safety in the region, and an indication of impending danger.
