What is Vivatmo oxycap?
The Vivatmo oxycap is not only a disposable mouthpiece; it is also used for sample preparation. This means exhaled breath is processed and prepared for measurement in the mouthpiece.
Chemical sample preparation
Several different chemical layers in the mouthpiece filter the exhaled breath in multiple ways, which reduces
- moisture in the sample,
- removes interfering substances and gases,
- and converts nitric oxide (NO) to nitrogen dioxide (NO2).
