This unit draws in room air and filters out all the other components. It then produces concentrated oxygen to replace the function of an oxygen cylinder.
What’s good about it
The main advantage is that your practice can do without the oxygen cylinders. This removes the associated dangers that comes with the constant moving, connecting and refilling of those cylinders. The unit is simply plugged into a power point and generates oxygen immediately. A patient can be connected directly to the concentrator to receive that oxygen.
The unit produces oxygen at a rate of eight to 10 LPM but needs to be primed a couple of minutes before use. By the time the patient is prepped it’s good to go. It can be attached to an anaesthetic machine to regulate the rate and flow of oxygen that the patient receives.
Using this concentrator works out much cheaper than oxygen cylinders that constantly need to be refilled. It also eliminates the possibility of running out of oxygen at the practice.
We’ve had the unit for 18 months now and it has worked faultlessly during that time. It requires zero maintenance. You don’t even have to check the seals or anything like that. It’s a fabulous machine once it’s set up.
What’s not so good
The unit is quite loud when it’s running. Its other drawback is that you can’t use it to run an oxygen flush through the anaesthetic circuit.
