| Description
| - A study has been carried out, involving three healthy volunteers, of the ammonia levels in breath exhaled via the mouth and via the nose and in the static oral cavity using on-line, selected ion flow tube mass spectrometry (SIFT-MS), obviating the problems associated with sample collection of ammonia. The unequivocal conclusion drawn is that the ammonia appearing in the mouth-exhaled breath of the three volunteers is largely generated in the oral cavity and that the ammonia originating at the alveolar interface in the lungs is typically at levels less than about 100 parts-per-billion, which is a small fraction of the total breath ammonia. This leads to the recommendation that exhaled breath analyses should focus on nose-exhaled breath if the objective is to use breath analysis to investigate systemic, metabolic disease.

- Koncentrace amoniaku v dechu zdravých dobrovolníků byla určena pomocí hmotnostní spektrometrie v proudové trubici s vybranými ionty (SIFT-MS). Měření bylo prováděno přímo v proudu vzduchu vydechovaného ústy, nosem a odebíraného z uzavřené ústní dutiny. Jednoznačným závěrem je, že převážná část amoniaku přítomného ve vzduchu vydechovaném ústy je produkována v ústní dutině a že alveolární koncentrace amoniaku je menší než 100 ppb. Závěrem je doporučení provádět analýzu amoniaku vydechovaného nosem, pokud je cílem stanovení systemické metabolické poruchy. (cs)
