The CWE's AVS-1 Advanced Ventilator System is a multifunctional microprocessor-powered animal ventilator.  It carries out neural ventilation control, pressure cycling, and volume cycling. Pressure-demand triggering, continuous CO2 ventilation, and options for external ventilator function control are further features. With the correct external valve assembly plugged in, the AVS-1 can ventilate animals up to the size of cats.

Flow-time ventilators produce inspiratory volumes by continuously supplying the animal with air for a predetermined duration. Because inspiratory time (TI), airflow, and respiratory rate (RR) may all be controlled independently, this method allows for a considerable deal of flexibility in respiratory timing. Apart from constant volume ventilation, there are several other ways that inspiration can end, such as end-inspiratory pressure.

The AVS-1's controls are systematically grouped into functional categories. Start Inspiration and Stop Inspiration are the two main groupings. For instance, an external logic signal, the initiation of Phrenic nerve activity, an animal's inspiratory effort (demand), or a clock can all initiate inspiration. A collection of related functions put an end to inspiration. It is possible to combine both modes; for example, you could use neural triggering to start inspiration and pressure to end it.
