Yes, it is possible to get too much oxygen from a concentrator or other oxygen delivery system. Geriatric nurse practitioner Christopher Norman shared his expertise regarding this important point of oxygen therapy:  “As I tell everyone, oxygen is a medication—it’s only available with a prescription, and there’s good reason for this. Just like any medication (over-the-counter or otherwise), too much can be harmful, too little is unlikely to be beneficial, and making adjustments with the amount is often best done with the help of someone knowledgeable (a health care provider, respiratory therapist, or other appropriate professional). Knowing how to properly use your supplemental oxygen equipment is crucial to successful use of this medication,” said Norman.
It’s a good idea to bring your new portable oxygen concentrator to your next doctor appointment to make sure the device is appropriate, working properly, and the settings are correct.
