A lung model of carbon dioxide concentrations with mechanical or spontaneous ventilation.
Modifications of a commercially available mechanical lung model (Vent-Aid Training Test Lung, Michigan Instruments, Inc., Grand Rapids, MI) enabled the study of CO2 concentration, distribution, and washout curves. An additional modification allowed either simultaneous or separate study of spontaneous ventilation and work of breathing.
