In artificially ventilated animals we investigated the dependence of the pulmonary diffusing capacities of nitric oxide (NO) and doubly 18O-labeled carbon dioxide (DLNO, DLC18O2) on lung expansion with respect to ventilator-driven increases in intrap

In this study, the temporal shape of voice-induced nitric oxide (NO) signals in exhaled air has been investigated in eight healthy individuals by means of laser magnetic resonance spectroscopy. The results of the experimental part have been compared

Because lung nitric oxide (NO) diffusing capacity (DL) represents alveolar-capillary gas diffusion, we queried as to whether disturbances of pulmonary gas exchange in interstitial lung disease (ILD) are appropriately reflected by using NO. In this pi

Nitric oxide (NO) is a novel indicator gas for investigating alveolar capillary gas exchange conditions. In clinical practice, pulmonary gas uptake is determined by measuring the single-breath diffusing capacity (DL,NO). Different algorithms are empl

In a human study we performed isotopic analysis in order to evaluate whether data on oxygen (O2) isotope fractionation at cytochrome oxidase can be applied to the entire O2 utilisation within respiration. For this purpose we measured the ratio of the

According to Fowler's method, anatomical dead space ( V D ) can be determined graphically or computer-aided by iteration procedures by which phase III of a fraction–volume expirogram F ( V ) is back-extrapolated by a straight line R ( V ). Whereas

To evaluate whether nitric oxide (NO) is an appropriate test gas for assessing pulmonary gas exchange, we determined the rates of disappearance from the alveolar space (lambda) of NO and singly and doubly 18O-labelled carbon dioxide (C16O18O, C18O2)

We studied the relative role of blood flow to limit oxygen (O 2 ) transport in patients suffering from chronic anemia and with respect to the transfusion of packed red cells. The stable isotopic oxygen molecules 16 O 2 and 16 O 18 O were used 16 O 2

The single-breath diffusing capacities for singly and doubly 18O-labeled CO2,[Formula: see text]and[Formula: see text], as well as for NO, were determined in seven anesthetized rabbits to investigate whether the theoretically predicted ratio of speci
