What are Oxygen Concentrators?

Oxygen concentrators are generally used for oxygen supply in healthcare services, especially in areas where liquid or pressurized oxygen is either too dangerous or not feasible, such as at your home or in portable clinics.

How do they function?

Oxygen concentrators have a molecular sieve that adsorbs gasses and functions on the rule of rapid pressure swing adsorption of atmospheric nitrogen onto zeolite minerals and then removing the nitrogen. In this type of adsorption system there is a nitrogen scrubber that allows the other atmospheric gasses to pass through but stops oxygen. This technology is a reliable and an economically feasible technique for small and medium-scale oxygen generation.

There are two types of oxygen concentrators:

1. Continuous flow mode

Many oxygen concentrators deliver a continuous supply of oxygen to the patient whether the patient breathes or not. Hence they are an excellent option for those who use them at night. It has no mechanism to detect the patient’s breaths but gives a continuous flow of oxygen which is available whenever the patient requires.

2. Pulse flow mode

The other kind of oxygen concentrators deliver a pulse flow to calculate the amount of oxygen a person needs when he breathes. There is no continuous supply of oxygen and on the other hand it is given only when the person inhales. Since they do not detect breaths during sleep, continuous flow is used during the night.

This concentrator features Invacare Sensi-Puls Technology that customizes the size of each bolus of oxygen to meet patient demand. The patient whether sleeping, relaxing or exercising, sensi-pulse technology adapts to the patient;s oxygen needs. This technology provides constant minute-volume which means that regardless of a patient;s breath rate at any given setting the same amount of oxygen is provided per minute. As the breath rate decreases, the bolus size increases.
  • The Respironics SimplyGo Portable Oxygen Concentrator is designed to offer continuous flow and pulse-dose delivery. It provides increased trigger sensitivity and a softer pulse for exceptional comfort. It has more than twice the oxygen output of any POC weighing ten pounds or less. The battery is immediately accessible and can be easily changed by the patients. There are no awkward external battery belts or connectors that get in the way, or hard-to-maintain internal batteries.
