For an accurate result it is important to breathe normally into the breathe ilo device once a day. Even though the CO2 method does not depend on the time of day, we recommend that you always measure in the morning after getting up in order to achieve the most reproducible measurement situation.
Please sit down calmly shortly before the measurement and not to be distracted.
Please inhale and exhale into the device in a relaxed and completely natural way. In other words, you should not take breaths that are too short or too long, as for example known from yoga practice, but you should breathe in and out completely naturally. In addition, nasal breathing must be suppressed. You can do this either by using the nose clip provided or by holding your nose closed with two fingers.
It may help you to practise calm breathing through the mouth before you put breathe ilo in your mouth and to breathe further into the device as soon as you have clicked on "Start measurement".
