Steady-state diffusing capacity determined by a simplified method.
One of the disadvantages of the method of Filley, MacIntosh, and Wright (1954) for determining the steady-state diffusing capacity is that it requires the collection and analysis of arterial blood. This adds materially to the time needed to make the determination. In normal individuals it is possible to use end-tidal Pco2 in place of arterial Pco2, or end-tidal concentration of CO as recommende...
متن کاملAn assessment of the steady-state carbon monoxide method of estimating pulmonary diffusing capacity.
For the past three years we have been using Bates's steady-state carbon monoxide technique for estimating the efficiency of gas transfer through the lungs as a routine laboratory procedure (Bates, Boucot, and Dormer, 1955). This paper reports certain formal investigations carried out to assess the usefulness and accuracy of the method and to help us to choose which of three ways in which the re...
متن کاملPulmonary diffusing capacity: a comparison of breath-holding and steady state methods using carbon monoxide.
Three methods are in current use for measuring the diffusing capacity of the lungs for carbon monoxide (DL). Two of these are steady state methods, and they differ in the methods used to calculate the mean alveolar carbon monoxide tension. Filley, MacIntosh and Wright (1) calculate the alveolar Pco indirectly, assuming the physiological dead space for carbon dioxide to be the same as that for c...
متن کاملSteady-state measurement of NO and CO lung diffusing capacity on moderate exercise in men.
Using a rapidly responding nitric oxide (NO) analyzer, we measured the steady-state NO diffusing capacity (DL(NO)) from end-tidal NO. The diffusing capacity of the alveolar capillary membrane and pulmonary capillary blood volume were calculated from the steady-state diffusing capacity for CO (measured simultaneously) and the specific transfer conductance of blood per milliliter for NO and for C...
متن کاملSteady State Detection of Chemical Reaction Networks Using a Simplified Analytical Method
Chemical reaction networks (CRNs) are susceptible to mathematical modelling. The dynamic behavior of CRNs can be investigated by solving the polynomial equations derived from its structure. However, simple CRN give rise to non-linear polynomials that are difficult to resolve. Here we propose a procedure to locate the steady states of CRNs from a formula derived through algebraic geometry method...
