The SAR-830 is a volume-cycled, positive-pressure ventilator. The standard model is suitable for use with rodents and similar size animals. A special version (Option 041) is set up particularly for mice and similar very small animals. Presentation To produce tidal volumes, a constant airflow is gated into the animal during inspiration. This FLOW RATE multiplied by the INSPIRATORY TIME gives the TIDAL VOLUME. RESPIRATORY RATE is set independently, and shown on a digital meter. This approach provides extraordinary flexibility — a wide range of volumes, breaths-per-minute, and I/E ratios are possible with no hardware changes, and using just three front-panel controls. The quiet internal solenoid valves and airpump (Model SAR-830/AP) are the only moving parts, which contribute to the long service life and excellent reliability of these units. Operating principle Setting up and operating the SAR-830 is easy: • First, select an appropriate respiratory rate for the animal, and dial it in using the rate meter. •Next, determine a tidal volume. • Finally, select a flow rate and inspiratory time to deliver that volume. Tidal volume vs. weight tables are provided to help in the selection of suitable parameters. Sighs can be produced manually at any time, and a HOLD switch temporarily suspends inspiration.
