Introduction: The document is a Smokerlyzer® MaternityCO Chart designed to help pregnant women stop smoking by monitoring carbon monoxide (CO) levels in their breath. It provides a correlation between CO parts per million (ppm) and the percentage of carboxyhemoglobin (%FCOHb) in the blood.

Key Data: The chart lists COppm values from 20 to 0, with corresponding %FCOHb values ranging from 5.66% to 0.00%. This data is crucial for assessing the impact of smoking on fetal growth, as higher CO levels are associated with decreased fetal growth.

Reference Study: The COppm-%FCOHb calculation is based on a study by Gomez C. et al (2005), which found that expired air carbon monoxide concentration above 5ppm in mothers and their spouses is linked to decreased fetal growth. This study is published in Preventive Medicine, volume 40, pages 10-15.

Publication Details: The document is identified as Issue 4, published in November 2015, with Part No: LAB469. Additional resources and contact information are provided through the website www.covita.net and phone number (800) 707-5751.
