Learning the lingo
Understand each part of the device and what it does.
What is the OG?
The Oxygen Generator (OG) is a battery-operated device that delivers continuous pure humidified oxygen directly to the wound to help wound healing. It comes with two (2) rechargeable batteries and a charging kit.
What is the ODS?
The Oxygen Delivery System (ODS) is a sterile, single-use, wound interface shaped like a wheel. The ODS lays between the wound and the dressing and delivers oxygen to the wound.
Oxygen is distributed from all areas of the “wheel” to evenly cover the wound bed. The holes in the wheel design allow wound exudate to flow freely into the dressing.
What is the canula?
What is exudate?
Exudate is a medical term for the fluid that comes out of a wound.
How to use the device, change the batteries, and disconnect components.
Turning it on
There is no ‘on/off’ switch to worry about. After you click in a fully charged battery, the device starts producing oxygen.
See tips: How to know it’s working
Changing the battery
To remove the battery, hold the device firmly. Place your thumb on the battery and slide upwards until it is disconnected.
Watch video: How to change the battery
PRO TIPS: Always keep one battery charging while the second battery is in use. We recommend having a set time each day or night to swap the battery, so you develop a pattern of charging and using.
Charging the battery
Your NATROX® kit has a charging unit that plugs into a normal socket. Insert the charger into the small, circular hole on the NATROX® battery. The charging port is seen after you slide the battery out of the device.
Watch video: How to charge the battery
PRO TIP: A yellow light flashes on the battery while it’s charging. The light stays solid after the battery is fully charged.
What to Expect
What typically happens during treatment with NATROX® O₂.
What to expect with NATROX® O₂ therapy
Average treatment time is 8 – 12 weeks; however, healing depends on many factors related to you as a patient. Variables include the type of wound and its condition.
Your clinical team will typically keep you informed of the healing progress they see when changing the dressing. They ultimately decide how long your treatment should last.
PRO TIP: NATROX® O2 works best by keeping it on 24 hours a day, 7 days a week (24/7). If you get restless at night, place the device where you are least likely to sleep on top of it.
Why has my wound fluid increased?
Oxygen increases wound healing. As part of this process, some people experience an increase in wound fluid. If you feel a build-up of fluid under your dressing or your dressing starts to leak, it is important to let your clinical team know.
Frequency of dressing changes
The dressing is usually changed at least once a week. This varies from patient to patient because dressing changes depend on the size and type of wound, as well as how long it has been treated.
Your clinical team will adjust your dressing change schedule to suit your individual needs over the course of your treatment.
Will it cause any pain or discomfort?
NATROX® O2 should not cause any pain or discomfort. Some patients report reduced pain using NATROX® therapy. If you experience any increase in pain, it is important to inform your clinical team.
Hints & Tips
Tips and tricks on daily use of the system.
The ABC’s of NATROX® O₂
Wearing it comfortably
Adjust the tubing so it is comfortable. Make sure the tube is not pulling too tight, as you do not want to disconnect it. Many patients place the device in their pocket. It can also be strapped to one’s leg and discreetly worn under pants or a skirt.
IMPORTANT: When positioning the tube, avoid sitting, standing, or resting on it during the day. For example, try not to place the tube behind your thigh. Also, it’s best to avoid placing the tube where it may create discomfort or prolonged pressure on the skin.
How to position the device correctly
If the tubing is bent, it can become kinked and restrict the flow of oxygen. For this reason, it’s advised to position the device so that the canula (e.g. tubing) is not bent in a pocket, as illustrated here:
When to use it
NATROX® therapy works best if you keep it on 24 hours a day, 7 days a week (24/7). For this reason, the device is designed to be very small and light. Plus, the system operates silently so you can get a good night’s sleep. A small, flashing green light stays on so that you know it’s working.
Showering with it
First check with your clinical team to make sure your dressing is waterproof*
Showering is possible if you disconnect the device beforehand.
Keeping you and your device safe during treatment.
Are there any side effects?
There are no known side effects or risks currently associated with NATROX® O2. However, if you experience any issues, it is important to inform your clinical team.
Are there any medications I should avoid?
There are no known (contraindicated medications) currently associated with NATROX® O2. However, if you have any concerns, speak to your clinical team.
Can I wear it during air travel?
Yes, although choosing to travel during treatment should be done so in discussion with the healthcare professional responsible for the care of your wound.
Download an Air Travel Information document which you can share with Airport Security, if required.
Can I manage dressing changes myself?
The system is so easy to use, patients can even apply it themselves from the comfort of home. However, the use of NATROX® O2 must always be under the supervision of a doctor, and changing the dressings yourself is something to discuss with your healthcare team.

What to do if the device doesn’t appear to be working.
How to know the device is working
If the small, green light on the OG is flashing, oxygen is flowing.
If the light stops flashing, then:
- Check the battery hasn’t become dislodged.
- Swap the batteries. A fully charged battery should last at least 24 hours.
If the light doesn’t start to flash again, contact your clinical team.
In case there is no green flashing light…
If there is no flashing green light on the NATROX® device, check that your battery is charged. If you confirm the battery is fully charged, contact your clinical team and they will advise you further.
Forgot to charge your battery?
No need to panic. Simply put the battery on charge as soon as you notice. If the battery you’re currently using stops working before the second one is fully charged, simply return to standard of care.
Once the battery is fully charged, insert it battery into the device, then resume your normal usage of NATROX® O2.
What to do if the tubing gets damaged…
No need to panic. Simply contact your clinical team who can help you get a replacement. In the meantime, return to standard of care. After replacing the tube, resume your normal usage of NATROX® O2.
