1. A system for monitoring carbon monoxide concentrations in an environment for use with an apparatus emitting carbon monoxide, said system comprising:

  • a. a carbon monoxide sensor for measuring a concentration of carbon monoxide in the environment, said sensor providing a sensor signal representative of the measured concentration of carbon monoxide;

    b. a memory storing data relating to past carboxyhemoglobin levels;

    c. a processor receiving and responsive to the sensor signal for generating an output signal indicative of the concentration of carbon monoxide, said processor;

    i. receiving the sensor signal from the carbon monoxide sensor, ii. determining the concentration of carbon monoxide corresponding to the sensor signal, iii. retrieving the stored carboxyhemoglobin level data from the memory, iv. calculating a carboxyhemogolobin level corresponding to the determined concentration of carbon monoxide and the retrieved carboxyhemoglobin level data, and v. storing the calculated carboxyhemoglobin level to memory for a predetermined period of time while the apparatus is shut off for retrieval by the processor and calculation of subsequent carboxyhemoglobin levels.
