How do I purchase an oxygen concentrator?

Your respiratory therapy begins at your physician's office, where your doctor will test your blood oxygen levels and identify the right therapy for your respiratory condition. Your doctor will prescribe a certain duration and medical oxygen flow rate for your therapy. 

This prescription should be followed closely to ensure the best possible therapy outcome. Your doctor will also advise you what type of oxygen therapy equipment your therapy requires.

When you have a script from your doctor, you can contact BOC Homecare on 1800 050 999 or homecare.au@boc.com to open an account and purchase or rent the prescribed oxygen concentrator.

For more information on opening an account with BOC Homecare, please see the Account opening page. 

How can I purchase other respiratory therapy products?

To buy respiratory therapy products that don't require a script from a doctor, such as nebulisers and humidifiers, call BOC Homecare on 1800 050 999 or email us at homecare.au@boc.com.

What are portable and transportable oxygen concentrators?

Portable oxygen concentrators (POC's) and transportable oxygen concentrators (TOC's) are portable or transportable devices used to provide medical oxygen therapy to patients at substantially higher oxygen concentrations than the levels of ambient air.

They are very similar to stationary home oxygen concentrators but smaller in size and more mobile. Both POC and TOC devices make it easier for patients to travel freely; they are small enough to fit in a car and many concentrators are now approved by airlines.

How do they work?

Portable oxygen concentrators (POC's) and transportable oxygen concentrators (TOC's) operate on the same principle as stationary concentrators, operating through a series of cycles. Normal air contains 21 percent oxygen combined with nitrogen and a mixture of other gases. A miniaturised air compressor inside the machine will pressurise this air through a system of chemical filters known as a molecular sieve. This filter is made up of silicate granules called Zeolite which sieves the nitrogen out of the air, concentrating the oxygen.

Part of the oxygen produced is delivered to the patient; part is fed back into the sieves to clear them of the accumulated nitrogen, preparing them for the next cycle. Through this process, the system is capable of producing medical grade oxygen of up to 90 percent consistently.

The latest models can be powered from mains electricity supply, 12v DC (car/boat etc.), and battery packs making the patient free from relying on using cylinders and other current solutions that put a restriction on time, weight and size.

Most of the current POC or TOC systems provide oxygen on a pulse (on-demand) delivery in order to maximise the purity of the oxygen. 

The system supplies a high concentration of oxygen and is used with a nasal cannula to channel oxygen from the concentrator to the patient.

What is the difference between a portable oxygen concentrator (POC) and a transportable oxygen concentrator (TOC)?

A truly portable device is defined as

  • A device that can be easily carried or moved and weighs less than 2.5 kg.

  • The ‘power’ is self contained (internal battery) and can provide medical oxygen at least 3 hours of continuous use.

A transportable device is defined as

  • A device that weighs over 2.5 kg and is not light weight enough to be easily carried while mobilizing, especially by a person dependent on medical oxygen.

  • A device that requires a trolley to transport extra batteries and is cumbersome on stairs and uneven surfaces.


Portable oxygen concentrator safety

Why is a specific prescription for POC or TOC required?

The prescriptions for continuous flow devices or OCD devices are not equivalent to settings on POC’s or TOC’s because no one model operates the same. All have different delivery methods, which impacts the volume of medical oxygen provided to the patient. A setting of “2” on a device may not equal 2 litres per minute as it does on a stationary concentrator or from a medical oxygen cylinder.

You should be tested with the device that you are intended to use. This is because the volume per breath determines the fraction of inspired medical oxygen (Fi02) the patient is receiving, and each patient breathes at different volumes.

The settings on each POC are reference points only and should not be considered the same Fi02 as continuous flow or OCDs at the same settings. There is no equivalency—the same setting does not deliver the same volume of medical oxygen between different POC or TOC models.

Therefore, regardless of the POC device used, oxygen saturation should be checked to ensure that patients are properly oxygenated with the device. To ensure your safety is not compromised, the POC or TOC prescriptions should be validated by your clinician. 

Your clinician should look at the following things:

  • Using the specific model of portable or transportable oxygen concentrator that you intend to purchase or rent.

  • At rest, during exercise and at night since respiratory rate varies the oxygen output on most models.

  • To rule out Sleep Apnoea since these devices use pulse dose technology and not all have a continuous flow setting option. Many patients wish to use POC/TOC or pulse doses 24/7 and many of them are not sensitive enough to trigger during sleep and most have a very long extended alarm setting (30 minutes +) if no oxygen is provided.

After the verification process, a new prescription stating the following should be provided to BOC Homecare to proceed to rental or purchase for the device that is intended to be used:

  • Flow rate specific to use pulse dose technology at rest

  • Flow rate specific to use pulse dose technology on exertion

  • Flow rate specific to use pulse dose technology nocturnally (at sleep)
