    30% lung capacity, as you may have guessed, is not great. It means your lungs are functioning only a third as well as a healthy person's. If this was determined by a Pulmonary Function Test (PFT), you can find some more details about what the PFT results mean in this article.


    If you're wondering how long someone can survive with such a lung capacity, the answer is we're just not sure. Having such low reserves means it might be very difficult for you to weather any respiratory infections. A bad cold might progress to pneumonia and do you in. On the other hand, it might not. You can compare some of your symptoms about the end stages of COPD in this article—you may or may not be as bad off as you think.


    And if you stay otherwise healthy, you might go on for some time. The body has a remarkable ability to adapt. Sure, you might not be able to do as much or to do it without considerable effort anyway, but if you are on continuous supplemental oxygen (as I'm sure you are), it can help keep your lungs going and improve the quality of your life considerably.


    Ultimately, you'll want to talk with your doctor about your personal health situation. That's where you'll be able to get the most clarity, as he/she knows you and your health history.

      I'm actually NOT on continuous O2. Shud I be? My pulmonologist did say that I MAY be able to recover 5% if I stop smoking. I plan to do just that. I've been a smoker since age 16 or b4... Maybe closer to 15. I have tried to quit b4, but it didn't take. I guess I have no choice now because I actually WANT to live now. (I didn't when I began smoking. I just got hooked instead) Just how long might I be able to go on. I was just diagnosed with both asthma and emphysema. Sux, yes. But, I knew about the risks even a decade ago but it didn't seem too important to me at the time. I see things differently now that I've remarried 4 years ago. I wish it hasn't taken so long to feel worthy of life. But, no time to grieve over past and all that now. Ought I to ask about O2? I see my doc again in 3 months. I'm also an A. S. sufferer and am on Duexis 800/26.6 (800mg ibuprofen with 26.6mg famotidine to coat my stomach) as an anti-inflammatory, and morphine sulfate-one 30mg tablet up to 4x/day, and 100mg Lyrica one every 12 hours, and Trazodone 100mg to take at night to help me sleep. I can't fall asleep any more. So I asked my doc for something. That's what he gave me. I still find myself up some nights well past when I ought to have been asleep. READ MORE

    Hi Kathy,


    Just to let you know, I am at 26% and have been under 30% for over 5 years.  I still work full time, although I am getting ready to retire soon.  I lead a full life with work, friends, and community interests. 


    We are all very different, so your progression with COPD may be very different than mine.  Just do what you can to improve your odds i.e., don't smoke, push a little each day with the exercise, and take all your meds as prescribed. 


    Good luck!

      What kind of work do you do? I'm at 38% and scared. I have BOS, not COPD. It may stabilize, but I can't immagine having a semi-normal life....

      I want to be alble to:

      1. Climb stairs (4 flights)

      2. Walk 1-2hrs +

      3. Not need oxygen 


      The docs don't answer my questions at all, so I have no clue.

       Hi just saw this web page. Could see people like me here (well better than me actually). I am a 55 year old male. Have had ASthma all my life. Make a long story short for the last 4 years have been told I have like 20% ling capacity.

       Since I have had ASthma all my life didn't pay too much attention to it.

       Till recently have been told that is not good.

        I see some people on here are living with 26% Lung capacity.

        I wonder if anyone could talk with me.

        My eMail is

       Keep up the good work Kathy..


        THanks for your time

    Hey, I have less than that and it's been over 10 years.  I,ve been on oxygen the whole time, stopped smoking immediately after first the hospitalization, and don't work. When I first became really disabled just walking to the bathroom was almost impossible. I built up my strength by walking on the treadmill and doing things around the house despite all the offers of help.  There were 2 years recently that I didn't walk and was on Prednisone for 10 months.  I lost a good amount of my stamina.  My strength is back up from walking every morning for at least 15 min and have reached 40+ minutes quite a few times.  I do drink wine at night and I only go to the Dr. once maybe twice a year. Yes, our bodies are all different. I think I've had my best times when there is some progress in my daily life.  In the beginning, doing the dishes or cooking anything was a miracle to me.  Now, I actually laugh a lot. Changing the  sheets is still a breathless chore but that's when husbands earn their keep!

      So good to read your reply. I just posted at 18% and still work also.  Have

      supplemental oxygen and do my housework, slowly, and still do much of the

      activities I have always done, with the exception of walking fast,tugging and

      pulling very much. I find it helpful to go to a store that offers carts for shopping.

      These are a lifesaver.  Also, treadmill and upper body exercises are good, too.

      Thanks, Joann Shaffer

    Generally speaking younger people can adapt better to a lower lung capacity than older people. The cause of the deficiency & rate of decline are very important. My decline from 70% to 40% in 1 year due to an auto-immune disease was punctuated with a dbl lung transplant. Hopefully ur looking into having an evaluation by a transplant center pulmonologist soon. Lung transplants are last resort, but you have to be healthy enough to pass at least 23 medical tests prior to getting on the list. READ MORE

    I'm at 30%, & have found the best for me is lots of exercise. I swim,run & cycle, exercising every day. I completed an Ironman event in may this year, 3.8k swim, 180k bike ride & 42.2 k run, the more I do the better I feel !
