The SAR-830 series ventilators are our most popular small animal ventilators! Their 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. Model SAR-830/AP (shown above) has the additional feature of pressure-cycling, where the lungs are always inflated to a set pressure on each inspiration. All models are available with Isoflurane or Halothane anesthesia.
Choose your model: 
SAR-830/P -- Volume or pressure-cycled operation. Has built-in airway pressure bar-graph, and analog pressure output signal. Requires a pressurized source of air, oxygen, or anesthetic mixture to operate.
SAR-830/AP -- Volume or pressure-cycled operation, with internal air pump for self-contained operation. Has built-in airway pressure bar-graph, and analog pressure output signal.
