Preoxygenation in healthy volunteers: a graph of oxygen "washin" using end-tidal oxygraphy
Abstract:
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.

Oxygen Delivering System II: Venturi Mask and Transtracheal Oxygen
Venturi Mask
The Venturi mask, named after the Venturi effect, is designed to deliver precise oxygen concentrations. It consists of a large tube with an oxygen inlet that narrows down, causing a pressure drop that pulls air in through adjustable side ports. The mask is a lightweight,...
