An informatic method is described for accurate on-line computation and recording of pulmonary transfer for carbon monoxide (steady state CO uptake with alveolar CO measured from end-tidal determination of gas) using fast response transducers for ventilatory flow and carbon monoxide tension. Special procedures for time alignement of flow and tension signal, and for determination of PACO by microcomputer, are described. The accuracy of the method was studied under informatic and non informatic methods PECO, PACO and TLCO values are in good agreement with those obtained by the conventional non-informatic method.
描述了一种信息学方法,该方法使用用于通气流量和一氧化碳分压的快速响应传感器,准确在线计算和记录一氧化碳的肺转运(通过潮气末气体测定肺泡一氧化碳来测定稳态一氧化碳摄取量)。描述了流量和分压信号时间对齐以及通过微型计算机测定肺泡一氧化碳分压的特殊程序。在信息学和非信息学方法下研究了该方法的准确性,呼气一氧化碳分压(PECO)、肺泡一氧化碳分压(PACO)和肺一氧化碳弥散量(TLCO)值与通过传统非信息学方法获得的值高度一致。
