C¹⁸O₂ Сarbon dioxide

¹⁸O₂ Сarbon dioxide

Chemical form: gas
Chemical purity > 99%

Product application
Carbon dioxide labeled with ¹⁸O (C¹⁸O₂) was used as a tracer gas for single-breath measurements in six anesthetized, mechanically ventilated beagle dogs. C¹⁸O₂ is taken up quasi-instantaneously in the gas-exchanging region of the lungs but much less so in the conducting airways. Its use allows a clear separation of phase II in an expirogram even from diseased individuals and excludes the influence of alveolar concentration differences. Phase II of a C¹⁸O₂ expirogram mathematically corresponds to the cumulative distribution of bronchial pathways to be traversed completely in the course of exhalation

Packaging
