Oxygen concentrator is a device that provides oxygen therapy to patients at substantially higher concentrations than that of ambient air and keeps the level of oxygen in their blood stable. It is a medical equipment which compresses the air around the patient to deliver it to him/her in a purer form. The supply of oxygen is continuous and unlike an oxygen tank, can never run out as long as the battery is powered or the compressor plugged into an electrical outlet. We have a wide range of top grade oxygen concentrators from experienced manufacturers. These devices, also referred to as oxygen generators or oxygen machines, provide a continuous stream of oxygen-enriched air and offer a cost-effective and most preferred at-home or on-the-go treatment.

How does an oxygen concentrator work?

An oxygen concentrator takes in the regular air in the room and compresses it using filters and sieve beds to filter out the other gases present, including nitrogen. Concentrated and medical grade oxygen is delivered to the user via a mask or nasal cannula. An oxygen concentrator delivers oxygen either as a continuous flow or in pulse doses. Pulse dose involves delivery of oxygen in doses or bursts, every time you inhale. It is based on the breathing rate and the amount of oxygen taken in. This ensures delivery of an appropriate amount of oxygen based on different activity periods –sleep, rest or daily tasks. If delivery is required constantly and at all times then a continuous flow system is necessary. For more sophisticated and efficient solution, pulse dose works better. The Invacare Platinum machine provides continuous flow up to 10 liters per minute. The oxygen machine from DeVilbiss is versatile in nature and delivers oxygen in continuous flow at 3 liters per minute as well as in pulse flow from 1-6 in Pulse Dose mode.  

The selection of an oxygen concentrator will depend on your lifestyle as well – active or at home. Additional considerations include weight, size, power options and battery life. If you are looking for a quieter oxygen machine then the size will be bigger. Smaller the size, the noisier it is.

Benefits of Portable Oxygen Concentrators

  • Portable oxygen concentrators use battery packs and allows the oxygen user to stay mobile. It is small in size and lightweight and so can be carried around easily. 

  • Since the portable oxygen concentrator runs on a battery, a fully-charged battery will keep the machine operable outdoors unlike a stationary unit. 

  • Apart from portability, an extra benefit is that this type also runs on AC and DC current. It can be plugged into an electrical outlet if at home and if in the car, it can be charged through a DC power cord thus preserving the battery for outdoor use. 

  • Multiple power options of AC and DC current and rechargeable battery make it a convenient machine to have at home and outdoors. 

  • Portable variety includes pulse dose oxygen concentrators which are smaller in size. Some portable oxygen machines provide continuous flow of oxygen but these are larger in size and have built-on wheels.  

  • The portable variety has more options in terms of usage – portable which is suitable for travel, portable type with continuous flow, portable type with high flow settings and oxygen machines less than 5 pounds. 

  • The portable/travel oxygen concentrator system from Inogen can be carried along on wheels or in a backpack on a plane, boat, car or train because of its small size. It is energy efficient and easy to use and has low power usage. 

  • The Respironics portable oxygen concentrator has high flow settings. Its oxygen concentration (at 5lpm) is 93% (+/- 3%). The Inogen One G3 system is portable and less than 5 pounds. It provides the same quality and efficiency on-the-go as well as at home.

Benefits of Stationary Oxygen Concentrators

Stationary oxygen concentrator systems provide a continuous flow of oxygen. It can be used 24x7 because to start functioning, it just needs to be plugged into a wall socket. The outflow of oxygen is higher (liter-per-minute) than the portable variety type and it can be wheeled around the house.
