If you are a patient that regularly uses continuous flow settings, you may be experiencing some dry and painful side effects caused by supplemental oxygen being delivered through your nasal cavities day in and day out, which can greatly deplete moisture from your nose. For those of you who do experience nasal dryness, the humidifier kit is the answer to ending painful nasal irritation. The instant you install the humidifier kit on the iGo you will begin to feel its benefits—simply fill the humidifier bottle with water to the fill line and each dose of continuous flow oxygen will be moisturized before it enters your nose. The humidifier kit can only be used in congruence with continuous flow oxygen settings, as patients who experience nasal dryness are typically on a continuous flow setting. In 3 simple steps you can begin to feel relief: attach the elastic bottle strap to the iGo, plug the bottle into the unit with the included tubing, and fill the bottle with water up to the designated flow line. This kit helps reduce and even eliminate nasal dryness due to oxygen therapy. It weighs 1 pound.
