Sorry I missed the O2 part of your question. Since I don't think it's possible to lower the diaphragm, the answer to your original question is no, you can't reduce the need for O2. However,some people who have had successful LVRS surgery or successful placement of the valves or vents have reduced their need for O2 significantly, so that is definitely a possibility.

I don't believe the diaphragm can be lowered because then it couldn't do the job it was intended to do. Take a look at where it's located and you'll see that if it were moved, it couldn't do the job of breathing because it would be too far removed from the lungs. If you qualify, it is possible to remove the upper lobes of the lungs. Then the lower lobes automatically raise, making the diaphragm freer. That surgery is called Lung Volume Reduction Surgery. Having the valves or vents inserted can cause areas of the upper lobes to reduce in size, thus allowing the lungs to move upward in the lung cavity and reduce he pressure on the diaphragm.

A trilogy machine is a non-invasive ventilation machine much like a bi-pap. The Trilogy can be calibrated to the patient much more closely than a bi-pap. It's designed to help maintain breathing during sleep and helps reduce the build-up of CO2.

Thanks for that info @A MyCOPDTeam Member,although not my question your answer covers things i had wondered about,thank you again...x

morning @clusdiaSchuster sorry iv never heard of such surgery. The only type of surgery iv heard of is valves inserted (lung reduction) and transplantation...hope this helps..x

hi @A MyCOPDTeam Member i believe its a machine similar to NIV (non invasive life support) that people sleep with to help blow out carbon dioxide from the body. hope this helps...x
