Time to Read: About 3 minutes

This information describes how to use a carbon monoxide testing device to help you quit smoking. It also explains why breath carbon monoxide testing can help you be successful in the Tobacco Treatment Program at Memorial Sloan Kettering (MSK).

You will be taking breath tests using a device called the iCOquit® Smokerlyzer®. It measures the level of carbon monoxide in your breath when you breathe out.

Why it’s important to test for carbon monoxide

A testing device gives you important feedback about your body. We often measure blood pressure, temperature, and oxygen to learn more about what’s happening inside the body.

The iCOquit® device measures carbon monoxide (CO) from cigarettes. It also measures CO from other tobacco products that can burn, such as cigars. This measurement is in parts per million (ppm). Carbon monoxide is a major cause of the shortness of breath and low energy many tobacco users feel.

Carbon monoxide is a toxic gas that blocks some oxygen from getting into your red blood cells. The device can help you get more in tune with your body by tracking carbon monoxide caused by smoking.

Why testing helps you quit if you smoke

The measurement you see after using the device tells you how much carbon monoxide is in your body. That information can motivate you and help you quit. That’s because it measures your progress during tobacco treatment.

You will likely see your carbon monoxide level change over time. Some people say the device makes them feel more responsible and in control. It gives them the power to make changes as they work on quitting for good. Along with counseling, the device helps support and motivate you during treatment.

As carbon monoxide levels drop, you may see other ways quitting helps you. You may be able to breathe more easily and have more energy. Your MSK tobacco treatment expert will talk with you about how your measurements can help you quit smoking.

What your breath test results mean

  • If the reading is 15 to 30 ppm, it means moderate to heavy smoking.
  • If the reading is 7 to 14 ppm, it means light smoking.
  • If the reading is 0 to 6 ppm, it means you quit and are no longer smoking.

•    Do not let water get into the breath or exhaust vents. 
•    Never put the device in liquid or splash it. 
•    Never use alcohol or cleaning solutions with alcohol on the device. This can harm the CO sensor inside.
