Preoxygenation in children using expired oxygraphy.
We performed preoxygenation on 25 patients, aged 1-12 yr. End-tidal oxygen sampling was used to find the duration of preoxygenation required to reach an end-tidal oxygen fraction of 0.9. All children reached this end-point within 80 s, which was markedly more rapid than that observed in adult subjects. The clinical applications of this form of monitoring in children are discussed.
