Abstract
Several modifications of the Bain system for nitrous oxide analgesia or general anesthesia were tested for rebreathing and retention of CO 2. The classic Bain circuit causes the most rebreathing as measured by the fractional concentration of CO 2 in a sample of inspired gas (Fi CO 2 ), but stimulation of the respiratory system seems to allow near normal end tidal CO 2 and arterial CO 2 tensions. The most predictable systems that have the least amount of rebreathing are those that have the least dead space.
