To perform the conversion, then, simply multiply the … The health effects of CO depend on the CO concentration and length of exposure, as well as each individual's health condition. CO concentration is measured in parts per million (ppm). Most people will not experience any symptoms from prolonged exposure to CO levels of approximately 1 to 70 ppm but some heart patients might experience an increase in chest pain.

Hourly (red circles) and Daily (yellow circles) averaged CO 2 values from Mauna 1-237) recommends an 8-hour TWA limit of 35 ppm with a 200-ppm ceiling.
