A mechanical lung model was used to investigate the effect of varying carbon dioxide production and deadspace on the end-tidal carbon dioxide levels achieved during mechanical ventilation when using the Bain, Humphrey ADE, and circle systems. Both factors had significant influence on end-tidal cardon dioxide concentration and could result in values in excess of those considered acceptable in clinical practice. The implications of the results are discussed.

Two cases of air embolism in patients anaesthetized in the sitting position are described. The emboli, though producing no signs and therefore probably small, were readily detected by the fall in the end tidal CO2 fraction. Techniques for the detection of air emboli are briefly reviewed.
