Abstract

A system is described which concurrently measures, breath-by-breath, the inspired and end-tidal concentrations of five gases, and alveolar and total ventilation. Gas concentrations are measured by means of a quadrupole mass spectrometer and mixed-expired carbon-dioxide concentration, required for the computation of alveolar ventilation, is computed as the volume-weighted average of expired carbon dioxide.

摘要

描述了一种系统，该系统可逐次呼吸地同时测量五种气体的吸入和呼出终末浓度以及肺泡通气量和总通气量。气体浓度通过四极质谱仪进行测量，计算肺泡通气量所需的呼出气二氧化碳浓度通过呼出气二氧化碳的体积加权平均值来计算。
