Even low carbon monoxide levels over long periods can have an impact on brain chemistry. While exact short term and long term CO levels recommended by ASHRAE, OSHA, NIOSH and other organizations differ, the consensus is that 9 ppm (parts-per-million) is the maximum indoor safe carbon monoxide level over 8 hours.

Even if you have smoked for a long time, stopping now will reduce your risk of developing health problems. Exposure to. 30 ppm of Carbon Monoxide throughout The ETCO levels measured were between 3 and 4 ppm, reflecting that the lung model was being “ventilated” with 30% oxygen.

Carbon Monoxide (CO), is often called the “Silent Killer” because of its ability to take lives quickly and quietly when its victims never even knew they were at risk. It is indetectable to humans, being both tasteless and odorless, and in high enough concentrations it can kill …
