Effective FiO2 Conversion for Infants on Nasal Cannula

In 1994, the NEI funded STOP-ROP (Supplemental Therapeutic Oxygen for Prethreshold Retinopathy of Prematurity), a randomized controlled clinical trial aiming to test the hypothesis that a carefully controlled increase in oxygen over conventional oxygen management would reduce the proportion of infants progressing from Prethreshold ROP to Threshold ROP.

Throughout the trial, investigators used the method of Benaron and Benitz for calculating effective FiO2 of infants on nasal cannula. For those who wish to use this calculation in their own research or clinical work, we present the Benaron-Benitz conversion, both as printable tables (suitable for bedside use or when no computer is available) and as a JavaScript computer application.

To help support further work in this important area, we have organized and documented a large portion of the STOP-ROP data in a user-friendly format, We offer it here to the research community.
