For those of you who are unaware of what an oxygen conserving device is, it is simply an oxygen tank regulator that will only allow oxygen to be dispensed when a patient is breathing. Because it only dispenses oxygen when you breathe, it increases the life of your oxygen tank by 300%. They are made to only give a dose of air to the patient when they are triggered by the patient’s breath. Standard oxygen regulators continuously dispense oxygen out of the tank which usually empties it in 1-2 hours, as opposed to oxygen conserving regulators which will make the same oxygen tank last 6-8 hours.

A pneumatic oxygen conserver does not use batteries but instead it has a small piston in the device that senses back pressure that is created when you exhale. When you inhale the backpressure is released allowing the piston to move and the oxygen stored in the oxygen conserver to be pumped to the user’s nose through a nasal cannula.

An electronic oxygen conserver regulator is similar to a pneumatic conserver, but the electronic mechanism inside regulates the burst of oxygen in a more precise dose and it runs off of batteries.

The advantage of using a conserving device is threefold. The conserving device allows the patient to only use oxygen from the tank when they are breathing. It will extend the life of the tank 3-5 times the life of a tank versus using a standard regulator and they are virtually maintenance free.

One of the most reliable and affordable oxygen conserving devices on the market today is made by Devilbiss, known as the Devilbiss PD1000 conserving device and is a battery operated conserver which is very sensitive to the patients breaths and also comes with a 3 year warranty. The Devilbiss conserving device fits most all oxygen tanks including the M6, M9, C, D and E tanks and is very lightweight.
