The SAR-830/AP Pressure/Volume ventilator with built-in air pump, is our most popular small animal ventilator. The legendary reliability rests on simple principles of operation and robust construction. Tidal volumes are generated by gating a known airflow into the lungs for a set inspiratory time. Only three controls — respiratory rate, inspiratory time, and flow rate are necessary to produce tidal volumes and respiratory rates over a wide range.
