Sample CO Logs

This CO Log shows CO levels typical for a non-smoker. 

• These results should be your goal! Note that all CO levels are 6 ppm or lower. 
• These results for a smoker do not mean it is okay to smoke. 
• There is no safe amount of smoking.

This CO Log shows low (Green) levels of CO in the early morning.

• These results are common when a smoker is not smoking during the night. 
• The higher levels during the day (Red bars) are consistent with smoking behavior. 
• This information could motivate you to wait longer before smoking each day, trying to stay in the green range for as long as possible.

This CO Log shows low (Green) levels of CO in the evening.

• These results are common when a smoker is smoking during the day and not smoking during the afternoon and evening hours. 
• The higher levels (Orange and Red bars) are as a result of smoking earlier in the day. 
• This information could motivate you to stop smoking earlier in the day. 
• Getting lower levels of CO may take longer than depicted in this sample CO Log.

This CO Log shows low (Green) levels of CO on the most recent day.

• These results show smoking on the first day (Orange and Red levels). 
• The lower levels (Green) show the results of not smoking on the current day. 
• This trend could motivate you to not smoke for consecutive days. 
• Actual reductions in CO with abstaining may take longer than depicted in this sample CO Log.
