Quantitative analysis of the effect of fraction of inspired oxygen on peripheral oxygen saturation in healthy volunteers

摘要

The international organization for standardization (ISO) 80601-2-61 dictates that the accuracy of a pulse oximeter should be assessed by a controlled desaturation study. We aimed to characterize the relationship between the fraction of inspired oxygen (FiO ) and peripheral oxygen saturation (SpO ) using a turnover model by retrospectively analyzing the data obtained from previous controlled desaturation studies.
