Oxygen Therapy

NRS maintains a complete inventory of Stationary and Portable Oxygen Systems, including Liquid Oxygen Systems, Oxygen Concentrators, Portable Oxygen Concentrators, Transfilling Concentrators, and High-Pressure Cylinders. Our in-house cylinder filling capabilities ensure quality oxygen products are always readily available. We have the oxygen therapy systems to fit any customer’s needs and help them maintain their quality of life.

Although not all systems will meet every customer's respiratory needs, we encourage you to call us today to see if you qualify and what your particular insurance will cover.

Oxygen Concentrators
Oxygen Concentrators are a convenient, dependable source of supplemental oxygen. The air we breathe is approximately 21% oxygen, 78% nitrogen and 1% other gasses. Oxygen Concentrators separate oxygen from nitrogen and other gases. The result is a constant supply of concentrated, high purity, supplemental oxygen that is delivered to the patient. Concentrators provide a source of oxygen to meet stationary oxygen requirements and require a continuous, reliable source of electricity for operation.

Portable Oxygen Concentrators
Portable Oxygen Concentrators, or POCs, are providing a convenient new way for oxygen users to stay mobile. These devices work the same as an oxygen concentrator, but on a much smaller level. For liter flows up to 3lpm, POCs use battery packs to provide hours of supplemental oxygen for people on the go. Most POCs are approved by the FAA for airline travel, so you can walk right on the plane. (Note: You will need to notify the airline about your oxygen and bring your prescription as well.)

Transfilling Oxygen Concentrators
In-home Transfilling Oxygen Concentrators give customers the power to maintain their own oxygen cylinders. Instead of being provided pre-filled oxygen cylinders delivered at regular intervals, customers can use this device to fill their own oxygen cylinders as often as they need. In a few short hours, customers can refill their oxygen cylinders and have their oxygen portability needs covered. Don't worry, the filling procedure is easy to learn and training will be provided upon setup.

Conserving Devices
An Oxygen Conserving Device regulates the flow of oxygen delivered by allowing oxygen to flow only during inspiration, as opposed to a continuous flow of oxygen, which is delivered from most oxygen devices.

Oxygen conserving devices can achieve 3:1 to 6:1 savings ratios. These devices need to be prescribed by a physician, as not all customers can tolerate them. Generally, oxygen saturation levels should be monitored to determine appropriate settings for a oxygen conserving device. The devices are available for high-pressure portable oxygen cylinders and liquid oxygen portable units.

Oxygen Cylinders
Portable high-pressure oxygen cylinders allow customers to leave their residence for a period of time, depending on the prescribed liter flow and size of the cylinder. Portable high-pressure oxygen cylinders must be returned to NRS to be refilled when empty. All portable oxygen systems need to be prescribed by your physician.

Depending on lifestyle needs and prescription, NRS provides four high-pressure cylinder types to meet the customer’s unique situation. The "E" cylinder, the largest portable, has a capacity of 670 liters of oxygen. The "D" Cylinder holds 410 liters. The "C" or M-9 cylinder, contains 240 liters, and the "B" or M-6 cylinder holds 160 liters. See our Cylinder Duration Chart for approximate durations for each size of cylinder and corresponding prescribed liter flow.

Liquid Oxygen
Liquid oxygen systems are designed to store and deliver oxygen to the customer at a physician’s prescribed rate. The system consists of a stationary tank and a small portable tank. The stationary tank supplies the customer with a source of oxygen while in their residence, and the portable unit, which is filled from the stationary tank, provides a portable source of oxygen to meet mobility needs. The stationary unit will be refilled by a NRS representative on a regularly scheduled basis. Liquid oxygen systems allow the user to be highly mobile.
