MODEL SAR-830 - VOLUME-CYCLE VENTILATOR
Reliable, versatile rodent ventilator
Features
•  Dependable, all-electronic ventilator
•  Wide tidal volume and rate range
•  Mice to Guinea pig size
•  Expandable to larger animals
•  Economical multiple-animal setups
•  Safe with oxygen and anesthesia
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. 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/A) are the only moving parts, which contribute to the long service life and excellent reliability of these units.
Operation
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.
Expandability
All SAR-830 series ventilators are easily expandable to ventilate larger animals, or several small animals simultaneously. This is accomplished using external valve assemblies plugged into an expansion connector on the rear panel. Each valve assembly requires a metered flow source. The external valves operate synchronously with the internal valves, but tidal volumes are independently set by varying the flow rate to each valve assembly.
SAR-830 series ventilators are compatible with oxygen and anesthesia. A source of low-pressure air is required for operation, except for models with an “A” suffix, which have internal air pumps. Anesthesia systems and a full range of accessories are also available. All models feature switchable 120/240VAC operation.

MODEL SAR-830/P VOLUME-PRESSURE VENTILATOR
Versatile rodent ventilator with controlled airway pressure
Features
• Dependable, all-electronic ventilator
• Pressure or volume-cycled
• Analog airway pressure signal
• Wide tidal volume and rate range
• Mice to Guinea pig size
• Expandable to larger animals
• Safe with oxygen and anesthesia
Model SAR-830/P Small Animal Ventilator can operate as either a volume or pressure-cycled ventilator. It is suitable for use with laboratory animals in the mouse to Guinea pig range of body weights. 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.
Operation
VOLUME MODE operation is identical to that of the SAR-830 ventilator, but the SAR-830/P can also operate in PRESSURE mode. A built-in solid-state transducer monitors airway pressure. The operator simply dials in the desired end-inspiratory pressure. During inspiration, airflow is introduced into the lungs until this pressure is reached, at which point inspiration is terminated. This mode is especially useful for very small animals, where hyperinflation of the lungs can be a problem. An output voltage corresponding to airway pressure is provided for external monitoring or recording. PRESSURE or VOLUME mode is selected with a single switch.
The SAR-830/P requires a pressurized air or gas source for operation. This can be any suitable breathing gas within the required pressure range, or the output from an anesthesia machine. The ventilator is also available with an internal airpump (Model SAR-830/AP) for completely self-contained operation. All models are compatible with inhalation anesthetics and oxygen. Complete anesthesia setups are also available.
Expandable
These units can easily be expanded to ventilate larger animals, or multiple small animals simultaneously by adding external valve assemblies. A metered flow source is required for each external valve assembly. These valves are available for animals ranging from mice to large dogs in size. Please refer to the accessories list for details.

SAR-830 SERIES VENTILATOR ACCESSORIES
External Valve Assemblies
External valve assemblies are used to expand the volume range of SAR-830 series ventilators, or to add additional ventilator stations. The valve assembly connects to the ventilator through a supplied 12’ cable, and acts as a slave to the SAR-830. The CTP-VA-1 (shown at right) is equivalent to the standard SAR-830 internal valves, and is used to create one or more additional ventilator stations. To connect more than one valve assembly, an MVA-4 electrical adapter is required (see below). A controlled flow source is required for each external valve assembly. Tubing and connectors are supplied.

CTP-VA
Flowmeter/Regulators
A regulated flow source is required for each external valve assembly attached to an SAR-830. Rotameter-type flowmeters are available as single units or as four-flowmeter manifolds (seen at right). The flowmeter manifolds can be used to mix anesthetic gasses, or as independent flowmeters for multiple valve assemblies. Digital mass flowmeters are also available where the highest accuracy is required. A metering valve should be ordered with each digital mass flowmeter.

EFM-4
Adapters and Miscellaneous
The MVA-4 Multi-Valve Adapter (shown here) allows up to four external valve assemblies to be attached to one SAR-830 series ventilator, for a total of five ventilator stations. Up to four CTP-VA-1 valve assemblies can be powered by one SAR-830 ventilator; two CTP-VA-3’s, or one CTP-VA-4, due to power supply constraints. Other configurations of the SAR-830 and its associated valve assemblies are available on special order. Complete anesthesia setups, including Halothane or Isoflurane vaporizers, are also available.
