A system for monitoring carbon monoxide in an environment which includes an apparatus emitting carbon monoxide, such as an internal combustion engine. A carbon monoxide sensor measures a concentration of carbon monoxide in the environment and provides an electrical signal to a processor that is representative of the measured concentration of carbon monoxide. The processor determines the concentration of carbon monoxide corresponding to the electrical signal, provides an output signal at or above predetermined carbon monoxide concentration thresholds, calculates an estimated carboxyhemoglobin level for the operator corresponding to the carbon monoxide concentrations calculated over time, and provides an output signal at or above predetermined carboxyhemoglobin thresholds. The signals are then received by one or more devices which provide textual, visual, and/or audible warnings indicating that environmental concentrations of carbon monoxide have caused a predetermined warning threshold to be met or exceeded. The signals may also be received by a device which shuts down the carbon monoxide generating apparatus.

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.
