NATROX® O2 is a small, battery-operated, wearable medical device designed to promote healing by continuously delivering a flow of highly concentrated topical oxygen directly to chronic or hard-to-heal wounds.

NATROX® Wound Care

NATROX® Wound Care began with a commitment to improve quality of life with topical oxygen therapy. Today, the company's product portfolio includes multiple solutions supporting chronic wound management.
Fax:(828) 484-6151 Website:

• Continuous therapy: topical oxygen delivered directly to the wound bed 24/7
• Can be used across all clinical and home care settings
• Lightweight, silent, and small enough to be carried in a pocket
• Comfortable: Propriety "wheel" design is made from soft, pliable material that molds around wounds
• Easy to use and compatible with most semi-occlusive secondary dressings
• Adjunct to standard of care- can be used with complementary products (compression therapy, total contact casting, etc.)


The NATROX® O2 system is a low-dose tissue oxygenation system intended to provide topical oxygen to aid in the healing of chronic wounds such as: skin ulcerations due to diabetes, venous stasis, post-surgical infections and gangrenous lesions; decubitus ulcers (bedsores); amputations/infected stumps; skin grafts; burns and frostbite.


The NATROX® O2 system is contraindicated for the following: ulcers due to thrombophlebitis; ulcers due to Reynaud's disease; wounds completely covered with eschar; wounds with fistulae or deep sinus tracts where the end cannot be probed; wounds covered with petroleum-based dressings; inadequate perfusion to support healing; ulcers resulting from infections, such as tuberculosis, syphilis, deep fungal infections; bites or third-degree burns.

Warnings and Precautions

Always refer to the IFU for the most up-to-date information.
Disconnect the NATROX® O2 OG device during a shower or bath. The NATROX® O2 ODS and dressing remain on the patient but will need to be kept dry. The OG and ODS can be safely reconnected afterwards.
The OG should not be sterilized, autoclaved or flushed with water or any other fluid.
Do not use if packaging has been previously opened or is damaged.

Adverse Effects/Reactions

Some patients may experience increases in exudate which can be a normal response to the use of topical oxygen.

Storage Requirements

The NATROX® O2 system should be kept dry and stored between 5°C and 35°C (41°F and 95°F). Sterile items should not be opened until ready to use.

Mode of Use/Application

Gather all supplies including the NATROX® O2 Oxygen Generator (OG), NATROX® Oxygen Delivery System (ODS) and a primary or secondary dressing that will absorb wound fluid, surgical tape, gloves, and wound cleaning supplies. If appropriate, cleanse the wound before applying the ODS. Remove the sterile ODS from its packaging. Position the ODS centrally to the wound, shiny beige side up and remember to consider the position of the tubing for optimum patient comfort. Insert the battery in the OG, check the green light is flashing, and attach the ODS tube via the twist-and-lock system (do not overtighten). ODS should be replaced at each dressing change and at least once a week.

Removal & Change Frequency

The NATROX® O2 batteries should be changed/charged every 24 hours. One is in use while the other is charging.
The ODS should be replaced with each dressing change, and at least once a week.

Additional Recommended Dressings

Any appropriate semi-occlusive dressing can be used over the ODS, as long as it completely covers the wound to seal in the oxygen. If the wound is highly exuding, an additional absorbent dressing can be used between the ODS and the secondary dressing.
