NATROX® O₂ Patient Help Center

The Oxygen Generator (OG) is a battery-operated device that continuously delivers oxygen directly to the wound bed to stimulate healing. It comes with two (2) rechargeable batteries and a charging kit.

The Oxygen Delivery System (ODS) is a sterile, single-use, wound interface shaped like a wheel attached to a tube. The ODS is placed between the wound and a secondary dressing as it delivers oxygen to the wound.

Oxygen is distributed from all areas of the “wheel” to evenly cover the wound bed. The openings in the wheel design allow wound exudate to flow freely into the secondary dressing.

The canula is the small, thin tube that connects the OG (the main part of the device) to the ODS.

Exudate is a medical term for the fluid that comes out of a wound.

There is no ‘on/off’ switch to worry about. Slide a fully charged battery into place until it clicks. The green light on the OG will begin to flash indicating it’s on.

See tips: How to know it’s working

To remove the battery, hold the device firmly. Place your thumb on the battery and slide upwards until it is disconnected.

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.

Your NATROX® O₂ kit has a charging unit that plugs into a normal socket. Insert the charger into the small, circular hole on the NATROX O₂ battery. The charging port is seen after you slide the battery out of the device.

PRO TIP: A yellow light flashes on the battery while it’s charging. The light stays solid after the battery is fully charged.

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.

Oxygen enhances 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.

The frequency of dressing changes may vary throughout the course of treatment. The ODS will need to be replaced with each dressing change, which should take place at least once every 7 days.

Your clinical team will adjust your dressing change schedule to suit your individual needs over the course of your treatment.

NATROX^® O₂ should not cause any pain or discomfort. In fact, many patients report reduced pain using NATROX O₂ therapy. If you experience an increase in pain, it is important to inform your clinical team.

Adjust the tubing so it is comfortable. Make sure the tube is not pulling too tight, as you do not want it to disconnect. 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.

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:

NATROX^® O₂ therapy works best if you keep it on 24 hours a day, 7 days a week (24/7). For this reason, it 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 lets you know it’s working.

First, check with your clinical team to make sure your dressing is waterproof*
Showering is possible as long as you disconnect the device beforehand.

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.

There are no known (contraindicated medications) currently associated with NATROX^® O₂. However, if you have any concerns, speak to your clinical team.

Yes, although choosing to travel during treatment should be done so in discussion with the healthcare professional responsible for the care of your wound.

NATROX® O2 is easy to use. Many patients can even apply it themselves from the comfort of home. However, treatment must always be under the supervision of a doctor. Changing the dressings yourself is something to discuss with your healthcare team.

If the small, green light on the OG is flashing, the device is working.

If the light stops flashing:

• Check the battery to make sure it hasn’t become dislodged.
• Swap the batteries. A fully charged battery should last at least 24 hours.

If the light still doesn’t flash, contact your clinical team.

If there is no flashing green light on the NATROX^® OG, make sure your battery is charged. If you confirm the battery is fully charged (indicated by a solid yellow light), contact your clinical team and they will advise you further.

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 into the device, then resume your normal usage of NATROX® O₂.

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.
