Oxygen Concentrators are medical devices that enhances the amount of oxygen level in the bloodstream of individuals who have low levels of O2 in the system. It draws from ambient air from its surroundings and deliver adjustable medical grade concentrated oxygen. The processed O2 delivered to the user is from 90-95% pure oxygen. They are electrically powered and plugged to the wall socket or battery operated for better portability and flexibility.
A portable oxygen concentrator receives air, purifies it, and then distributes the newly formed air. Before it goes into the concentrator, air is made up of 80 percent nitrogen and 20 percent oxygen. After the air goes through the oxygen concentrator, it comes out as 90 to 95 percent pure oxygen and 5 to 10 percent nitrogen. The nitrogen is separated to give the patient the highest dose of oxygen possible, as it is difficult to get that percentage of oxygen without the help of a medical device.
There are two types of oxygen concentrators – portable and stationary.
Portable oxygen concentrators are alternatives to compressed oxygen tanks. They are ideal for patients who wish to retain an active lifestyle and enjoy life on the go while requiring oxygen therapy. Portable concentrators run off of batteries that are rechargeable off of either AC or DC power. Furthermore, as long as the portable machine has a source of power (AC, DC, or battery) the unit will continue to produce medical grade oxygen.
Stationary concentrators deliver medical grade oxygen to patients who need it for extended use in the home. Also known as home concentrators, these devices are meant to be used by patients in their homes for day and night-time use while portables are great for when a patient is away from home.
Both portable and stationary devices operate in the same fashion. They both provide medical grade oxygen by taking in room air through an intake vent and then cleaning and separating the other gasses from the oxygen. The oxygen is then compressed and then delivered to the patient via a cannula or mask.
