초록

Bymixer devices and methods for sampling or obtaining data from mixed respiratory gases in a ventilation circuit. Respiratory gasses from a plurality of consecutive breaths become mixed within a mixing chamber of the bymixer and samples or data are obtained from such mixed respiratory gasses. Optionally, the volume of the mixing chamber and/or the resistance to flow into or through the mixing chamber may be selectable or adjustable.
