What is an Oxygen Concentrator?
An oxygen concentrator or otherwise referred to as oxygen machines, O2 concentrators or oxygen generators.
An Oxygen Concentrator is a medical device that concentrates oxygen from the air and stores it in a cylinder, which is later administered to the individual who requires it, by means of a mask or pipe to the nasal passage.
What does an Oxygen Concentrator do?
Oxygen Concentrators, regardless of the name, provide an affordable way for oxygen therapy patients to supplement their oxygen needs without the need of bulky, heavy oxygen tanks. Unlike tanks, oxygen concentrators do not run out of oxygen. A personal oxygen concentrator pulls-in regular room air, filters out some of the other gases present and delivers concentrated, medical-grade oxygen.
Who are these individuals?
Oxygen concentrators are used by people who have a medical condition that results in low levels of oxygen in the blood. It is known as Hypoxemia. A person with hypoxemia experiences shortness of breath.
How does an Oxygen Concentrator function?
Oxygen concentrators are man-made trees. Oxygen concentrators give you purified and concentrated oxygen. An oxygen concentrator takes in air and purifies it for use by people requiring medical oxygen due to low oxygen levels in their blood.
They achieve this by a technique called pressure swing adsorption. In layman terms, what it actually does is,
- it takes in the atmospheric air and pressurizes the air against an adsorbent bed.
- Nitrogen is retained in the bed and only oxygen with purity up to 93% (+/- 3%) is taken out from the other side of the bed which is then passed through HEPA filters.
- HEPA filters can be thought of as a very strict watchman that doesn’t let 99.97% of particles up to the size of 0.3 µm to pass through. You shouldn’t expect anything less because you deserve only the purest.
An oxygen concentrator takes in air and purifies it for use by people requiring medical oxygen due to low oxygen levels in their blood.
It works by:
- Taking in air from its surroundings
- Compressing air, while the cooling mechanism keeps the concentrator from overheating
- Removing nitrogen from the air via filter and sieve beds
- Adjusting delivery settings with an electronic interface
- Delivering the purified oxygen via a nasal cannula or mask
