| Description
| - Hmotnostní spektrometrie v proudové trubici s vybranými ionty (SIFT-MS) byla použita pro studium dechu tří zdravých dobrovolníků. Byly porovnány hodnoty koncentrací devíti stopových látek. Koncentrace acetonu, metanolu a isoprénu byla stejná v exhalacích ústy jako v exhalacích nosem. Koncentrace amoniaku, etanolu a kyanovodíku byly naproti tomu výrazně nižší v nosních exhalacích než v exhalacích ústy a nejvyšší byly ve statickém vzduchu odebraném z ústní dutiny. Hladiny formaldehydu v dechu a v ústní dutině byly nižžší než v okolním vzduchu. Výsledky ukazují že ústní dutina výrazně ovlivňuje složení dechu. (cs)
- Analyses have been performed, using on-line selected ion flow tube mass spectrometry (SIFT-MS), of the breath of three healthy volunteers, as exhaled via the mouth and the nose and also of the air in the oral cavity during breath hold, each morning over a period of one month. Nine trace compounds have been quantified and concentration distributions have been constructed. Of these compounds, the levels of acetone, methanol and isoprene are the same in the mouth-exhaled and the nose-exhaled breath; hence, we deduce that these compounds are totally systemic. The levels of ammonia, ethanol and hydrogen cyanide are much lower in the nose-exhaled breath than in the mouth-exhaled breath and highest in the oral cavity, indicating that these compounds are largely generated in the mouth with little being released at the alveolar interface. Using the same ideas, both the low levels of propanol and acetaldehyde in mouth-exhaled breath appear to have both oral and systemic components.
