Oxymizer ® Disposable Oxygen Conserver


The Chad Oxymizer ® Disposable Oxygen Conserver offered by Drive Medical facilitates the delivery of continuous high-flow oxygen therapy. The Oxymizer can be used with compressed gas cylinders, concentrators, and liquid oxygen. The Oxymizer increases the proportion of oxygen flow during early inspiration while achieving saturation levels and providing a reduction in total oxygen delivered. This unique technology provides an up to 4:1 savings ratio; combating the waste and expense associated with continuous flow oxygen. This device is beneficial to patients who either have high liter flow settings or cannot currently tolerate standard conserving devices. The Oxymizer provides a comfortable alternative to an oxygen mask allowing patients to eat, drink, and talk comfortably. The Oxymizer is available in a mustache style or concealable pendant style.. Consult your physician for a flow rate to use with the Oxymizer. The Oxymizer should be replaced once every three weeks or as necessary.

Customer Questions and Answers

I am on 6 LPM continuous oxygen right now. I am wondering if I can use my oxymizer with my porrtable oxygen concentrator which is NOT continuous but supplies oxygen by demand. The highest setting my portable concentrator offers is 5 LPM.

Reviews from users of your Oxymizers say the are stiff & uncomfortable. Why would they need to be stiffer than regular, soft comfortable cannulas we use daily? you are not trying to develop a more comfortable delivery system, why not?

Asked by: Denise NewFibrosis
I agree many users find the Oxymizer stiff and uncomfortable. Creating a softer cannula portion would make it more comfortable. Also, many patients have trouble with the size of the nasal prongs irritating the nares. Any possibility of making slightly smaller prongs?

Customer Reviews

Oxymizer® Disposable Oxygen Conserver is rated 2.8 out of 5 by 4.
Rated 4 out of 5 by from Pendant Nasal O2 Cannula I suffer from severe Pulmonary Fibrosis & require supplemental O2 X 24HRS/day. As a result of my illness, I required 10L/minute at rest & 15L/minute during activity via a standard nasal cannula. Yes, there are minor design problems with the nasal portion. However, I have found that using humidified oxygen, Arm & Hammer "Simply Saline Nasal Mist" and "Ayr Saline Nasal Gel" make the cannula far more tolerable. Furthermore, my oximetry confirms that I am able to tolerate a lower oxygen flow. The lower your oxygen, the lower the probability of developing "Oxygen Toxicity" (Google it).

Rated 1 out of 5 by from Good Idea, Poor Priduct I am in Ichsner Hospital being evaluated for lung transplant, and was put on the Optomizer in hopes of conserving oxygen and better delivery during exercise. At first glance, this is a very good idea, but in practice I found the hard cannula to be very uncomfortable, causing nasal irritation and painful sores inside my right nostril. No reason this oxygen conserver could not have been made softer like the canulas I normally wear. Good idea; Final product not so god.

Rated 4 out of 5 by from Oxymizer Pendant I found the hard Oxymizer Pendant cannula to be very uncomfortable, causing nasal irritation inside my nostrils. No reason this oxygen cannula could not be made softer like the soft cannulas I normally wear. Please discuss this with the people who manufacture it. Maybe the whole thing could be made softer? Thanks.

Rated 2 out of 5 by from Highly Effective But Uncomfortable and Cumbersome As a constant flow oxygen patient, I find the Oxymizer extremely helpful in lowering the LPM that I require during routine exercise and activities. The drawback is the HARD plastic tubing and cannula which is very inflexible. In cold weather it's virtually impossible to use. Even the nostril portion is a very hard plastic. I would give 5 stars and highly recommend this product if there were not so many design flaws.
