摘要

呼吸测量允许研究某些肺变量。作者表明，平均肺泡PCO/sub - 2/(与正常受试者动脉PCO/sub - 2/密切相关)和容积系列死腔可以在线测量，每次呼吸。对这些变量(如PCO/sub 2/、PO/sub 2/、R、N/sub 2/、Ar/N/sub 2/)的呼吸内谱的进一步研究有望提高对正常和受损肺功能的理解。

Physiological inferences from intra-breath measurement of pulmonary gas exchange

Intra-breath measurements allow study of certain pulmonary variables. The authors show that mean alveolar PCO/sub 2/ (which closely reflects arterial PCO/sub 2/ in normal subjects) and volume series dead space can be measured online, breath-by-breath. Further study of the intra-breath profiles of such variables (e.g. PCO/sub 2/, PO/sub 2/, R, N/sub 2/, Ar/N/sub 2/) are expected to improve understanding of both normal and impaired lung function.<>
