Model for capillary-alveolar equilibration with special reference to O2 uptake in hypoxia.

摘要: Abstract This paper presents a simple model for the study of diffusion limitation effects in capillary-alveolar gas transfer. The decisive parameter to determine extent is shown be dimensionless ratio D/(Qβ) (D, diffusing capacity, Q, blood flow; β, capacitance coefficient or effective solubility blood). predicts considerable pulmonary O 2 uptake hypoxia, which sets an upper limit level exercise at high altitude.
