Additional information For all pregnant women with exhaled breath tests between 4 and 9ppm of CO, it is important to have a conversation about: other potential environmental sources of exposure (for example, domestic or portable fuel burning appliances, vehicle exhausts and incense burners) signs of CO (soot or stains around fuel burning appliances, yellow or orange flames except for fuel-effect fires, pilot lights that frequently blow out, and blocked or obstructed fixed ventilation or flues) symptoms to be aware of (for example, headache, dizziness, flu-like symptoms, weakness, drowsiness, confusion and/or nausea) ways to reduce levels (for example, regular maintenance of fuel burning appliances by a registered engineer, ventilate indoor spaces, have chimneys swept at least once a year by a qualified sweep, and minimise exposure to potential environmental sources of exposure, for example, vehicle exhausts and incense burners) Regardless of the potential source of CO exposure, if you feel concerned about raised levels of CO and/or signs and symptoms of CO poisoning, please use your clinical judgement and follow the local trusts policies
