To correct for
dilution of alveolar air from dead volume air in the breath sample and
to normalize the concentration of each analyte to correctly reflect the
breath concentration, we measured the carbon dioxide concentration in
each canister sample using a C[O.
Although the red blood cells are exposed to alveolar air only for a
fraction of a second, gas exchange between alveoli and capillaries takes
place very efficiently because there is an extremely large surface area
between the blood and the air. Portable units for analyzing the CO content
of expired alveolar air offer a noninvasive measure. |
