Model: SAR-830/AP    Cat.No.: 12-02100
Manufacturer: Cwe, Inc.

Rodent ventilator, volume/pressure-cycled, with* internal air pump.
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. See Specification. Download pdf Brochure.
* 3 other models are avilable:
SAR-830 (p/n 12-01000) - Rodent ventilator, volume-cycled, without air pump
SAR-830/A (p/n 12-01100) - Rodent ventilator, volume-cycled, with internal air pump
SAR-830/P (pn 12-02000) - Rodent ventilator, volume/pressure-cycled, without air pump
OPTION for all models: Anaesthesia system setup - comprising of a Flowmeter and a Vaporizer (Isoflurane or Halothane).

Model: MRI-1    Cat.No.: 12-07000
Manufacturer: Cwe, Inc.

A small animal ventilator designed for use in MRI and other high magnetic field environments.
It comprises a microprocessor-based control unit and a set of remote, pneumatically operated, non-magnetic valves. The MRI-1 can operate by itself or can be controlled and/or monitored by a computer. Download pdf Brochure.
The available Non-magnetic Valve sets are:
Model XS (p/n12-07100) - for mouse & rat (supplied standard with MRI-1)
Model S (p/n 12-07200) - for rabbit and large rodents
Model M (p/n 12-07300) - for cat to monkey
Model L (p/n 12-07400) - for dog to goat.

Model: SAR-1000    Cat.No.: 12-03000
Manufacturer: Cwe, Inc.

Small animal ventilator for mice, rats, and other small animals. New Model.
Digital control and advanced sensor technology. All settings such as respiratory rate, tidal volume, end-inspiratory pressure, I/E ratio, and more, are set directly from the front panel. All user-settings and computed measurements (such as Minute Ventilation) are clearly displayed on the backlit LCD panel. An LED pressure bargraph shows instantaneous airway pressure for easy monitoring of ventilator operation.

Model: MicroVent 1    Cat.No.: 000A3760
Manufacturer: Hallowell EMC

A dual mode ventilator: Intermittent Positive Pressure Ventilation (IPPV) and High Frequency Oscillatory Ventilation (HFOV).
There are just four parameters to control: Oxygen flow, Frequency (breaths per minute), Amplitude (tidal volume) and Mean Airway Pressure (Mean Paw).
In IPPV mode the frequency selectable ranges from 75 to 240 breaths per minute (BPM). The tidal volume (TV) deliverable is from zero to 10ml. This does not limit the usefulness of the MicroVent 1 to extremely small animals.
In the HFOV mode the frequency range to 750 to 2400 "breaths" or more accurately cycles per minute. The "tidal volume" during HFOV is generally an order of magnitude less than it would be during IPPV and is now used to set up an oscillation of the molecules of gas from the breathing system down to the alveoli. The entire breathing system has a volume of less than 1cc. Download pdf Brochure.

Model: Multiflow 2002+I:E    Cat.No.: 000A3471/42
Manufacturer: Hallowell EMC

Anesthesia Ventilators with Adjustable I:E Ratio - electronically controlled, time-cycled, volume constant, pressure limited.
Electronic control: Eliminates the substantial driving gas required to operate pneumatically controlled ventilators.
Time cycled: Insures consistent, repetitious, dependable breathing. The respiratory rate is adjustable from 6 - 40 breaths per minute (BPM).
Volume constant: Insures that each delivered breath will have essentially the same volume, independent of changes in patient compliance and airway resistance. The deliverable tidal volume (TV) range is from approximately 20cc to 3,000cc.
Pressure Limited: Provides for patient safety by limiting the maximum working pressure (MWPL) to an adjustable pressure range of 10 - 60 cm H2O.
Equipped with dual airway pressure alarms that monitor and sound when the peak inspiratory pressure (PIP) of any breath either exceeds the preset maximum working pressure limit (MWPL) or fails to reach 6 cm H2O as in the case of a disconnect. The Low Supply Gas Alarm, available as an option, would sound when the supply gas pressure falls below 35 psi, 2.4bar.
