How Many Hours Do I Need To Use My Oxygen?

Dear Dr. Mahler:

For the past 2 years, I have been using oxygen since being discharged from the hospital after a COPD flare-up. I was told to use the oxygen at a setting of 2 for 24/7. However, I find this requirement somewhat onersome.

I am 72 years old and use a nebulizer for my three different medications. I also go to a maintenance pulmonary rehab program at the local hospital here in Dayton.

My question is, How many hours do I really need to use the oxygen? When I take the oxygen off for 5 - 10 minutes, my sat stays around 87-88% and my breathing is fine. I an very conscientious about using oxygen at night when I sleep.

Thanks for your answer.

How Much Oxygen Should I Use?

Dear Dr. Mahler:

I am 71 years old and have severe COPD for several years, but am doing fine and have adjusted to my situation. I use oxygen 24/7 from a stationary concentrator at home and from a POC with activities and travel. I fly (at least before COVID-19) to visit my children/grandchildren in Wisconsin.

However, I am confused about my oxygen flow rate. My doctor told me that 2 liters/minute is what I need at rest, and my oxygen saturation level is usually 91-92%. However, I turn up the oxygen to 4 liters/min because I feel better when my saturation level is 94-95%.

My POC has pulse flow and I use the highest number – 5 – which maintains a saturation around 91% when I am active.

What are your thoughts on this?

Nebulizer Therapy For COPD – Can It Help Me Breathe Easier?

There are four major reasons why your health care professional might prescribe nebulizer therapy: 1) cognitive impairment - such as a memory problem (dementia) or confusion; 2) problems with use of hands - such as arthritis of the hands and wrists or tremor; 3) difficulty coordinating release of the medication from the device, not inhaling correctly, and not holding your breath long enough; and 4) a low inspiratory force required to break up and then inhale powder particles out of a dry powder inhaler.
