Abstract Development and testing of theoretical models of ventilation in the workplace. The models were: single compartment, multicompartment and transition time models. Equations describing the circulation of gases were derived for the models, and the results compared with experimental data concerning the dilution and ventilation of nitrous oxide in the air of several locations. The models gave similar results, confirmed by the data.
