Oxygen regulators can have either a CGA 870 yoke style fitting ( for E or D size cylinders ) or a CGA 540 nut/nipple style fitting (for K, M, or H size cylinders) as inlets. They can be configured in a 50 PSI preset pressure mode, an adjustable pressure mode (most commonly 0-100 PSI) or in a custom configuration utilizing, adjustable pressure and flow rate options.

Most respiratory and anesthesia equipment is calibrated at 50 PSI pressure. Therefore, when supplying the gas necessary for powering these products, a 50 PSI preset regulator is a good option to use. The pressure is fixed; it cannot be adjusted (preventing incorrect operation of the device it is being used with) . The regulator can come with a standard gas specific DISS 1240 outlet, an adjustable Thorpe tube flowmeter, a medical quick connect coupler, or a combination of these options. Configuring the regulator would allow it to be used in a variety of applications.

In a lab or a biomed department, an adjustable PSI regulator is often the item of choice. Pressures other than the 50 PSI standard are used in testing equipment for proper functionality. Common configurations are 0-100 PSI and 0-30 PSI (for use with Pulmonary Function equipment).

On occasion, unusual situations calls for a configuration that is difficult to understand or find – thus the need for specialty oxygen regulators.

CO2 regulators are available in either CGA320 style (for H cylinder) or CGA940 style (for D or E cylinder) . Depending on the application or procedure, a number of options are available.WT Farley offers CO2 regulators that are preset at 50 PSI or adjustable from 0-100 PSI (with standard DISS 1080 outlet adapter), as well as adjustable liter flow models (0-12 LPM) . These can be used in Biomed, Respiratory Therapy, Operating Room, or Clinical Laboratory settings. Other custom options are available; let us know how we can help meet your clinical situation.

Another related item that W.T Farley offers is the CO2 Insufflation yoke and manifold that is used in the O.R. setting. These accessories will interface with Insufflators and are available in a number of custom configurations as well as standard ones. The CO2 Insufflation yoke with cylinder pressure/contents gauge (MF-SP16INSUF) offers a visual indicator of cylinder contents while in use (reducing the chance of having an empty cylinder in the middle of a procedure). Our MB-SPCO2INSUF is a unique device manifolding two cylinders together; when one cylinder is empty, simply shut it off and turn the full one on. The empty one can then be replaced at the end of the procedure. This not only insures a sufficient supply of gas to complete the procedure, but it also eliminates CO2 waste as well. Important note: a partial cylinder will not have to be discarded because it does not have sufficient gas to complete a procedure. Carbon oxide regulators can be purchased by WT Farley.

Nitrogen is a gas that is used mainly in the Operating Room as a means of supplying power to pneumatic tools used there (saws, drills, etc). The range of pressure required is routinely 0-200 PSI adjustable pressure; however, other configurations are available and can be utilized. The regulator inlet for “H” or “K” size cylinders is CGA 580 and CGA 960 for the “E” size cylinders. The outlet is normally a Shrader style female quick connect coupler, or a DISS 1120 Male standard threaded fitting. An extension hose would then be utilized to interface between the regulator outlet and the tool.
A unique option is the dual outlet adjustable Nitrogen regulator that allows 2 devices to be attached and adjusted independently from 1 single cylinder. This is available in only the CGA 580 style inlet. It can also come equipped with either the Shrader style couplers or DISS 1120 Male fittings as outlets.

In-line style Nitrogen regulators utilize wall outlet gas when powering O.R. tools. Standard pressure range is also 0-200 PSI, with other options available, and can be configured with DISS 1120 or Shrader style inlets and outlets. It is also available in a dual outlet configuration where 2 tools can be independently operated at different PSI if necessary.

On occasion, a need will arise for sub-ambient gas in the hospital. This is air comprised of less than 20.9% Oxygen. Since air is essentially 20.9% Oxygen and balance Nitrogen, this can be accomplished by adding Nitrogen to Medical Air, and utilizing an Oxygen Monitor to see exactly what the percentage of Oxygen is in the mixture. Regulators with back pressure compensated Thorpe tubes are available in both CGA 960 and CGA 580 configurations to allow Nitrogen to be dispensed in flow rates that are accurately calibrated for Nitrogen. They can also come with an optional 50 PSI DISS 1120 check valve outlet for attachment to a ventilator or blender.

Many hospitals are currently using Heliox as an alternative to air/oxygen mixtures when treating patients with severe airway obstructions. Heliox is simply a combination of helium and oxygen provided at 80% helium/20% oxygen as well as 70% helium/30% oxygen mixtures. This combination is less dense than air (and lighter than pure oxygen) which in turn provides improved gas exchange, lowered resistance when breathing, and a reduction in the amount of work required to maintain a normal level of breathing. Heliox therapy is used for a variety of conditions such as asthma, tumors in airways, anaphylaxis, chronic obstructive pulmonary disease (COPD), and other breathing-related illnesses.

Heliox regulators have standard CGA fittings assigned – CGA 280 for the H or K style cylinders, and CGA 890 for the E size cylinders. Many ventilators currently are equipped with a gas-specific inlet for use with Heliox mixtures. This is assigned as DISS 1180, and cannot interface with the standard Air, Oxygen, and Helium DISS fittings.

W.T Farley provides a number of Heliox regulators to assist in providing this modality – Regulators with 0-16 LPM flow meters that can also come with an optional DISS male 50 PSI auxiliary valve for attachment to a ventilator, 50 PSI preset, and 0-100 PSI adjustable style regulators in both the CGA 280 and CGA 890 configurations. All of these will come with the correct CGA and DISS fittings that are specific for Heliox–no adapting or modification will be necessary. We also provide high pressure hose that will interface between the regulator and the ventilator in any length that you require.
