Preoxygenation in healthy volunteers: a graph of oxygen "washin" using end-tidal oxygraphy.
End-tidal oxygen fractions (FE'O2) have been measured in 40 healthy volunteers breathing 100% oxygen. On the assumption that FE'O2 is a good measure of alveolar oxygen, we have drawn a graph of oxygen washin vs time. Clinical applications are discussed.
