@A MyCOPDTeam Member I usually do it 10 times.....slowly....as a general rule. But sometimes when I am in one end of the Casino and it is time to meet hubby way at the other end.....I walk real fast to meet up with him I do the exercises while walking, then I sit there and do the breathing exercises until I feel fine again, usually just a few will do.

There are breathing exercises that help to increase your oxygen levels. My O2 is usually about 92 to 94, but if I do the exercises it can go up to 95. What I do is breath in through my nose as deep as I can, then exhale through pursed up lips real slowly. (Pursed up lips means all tight like as if you were whistling)

If your O2 levels are chronically low, the answer to your question is yes, adding supplementary O2 is the only way to ensure that they stay at safe levels. However, you're nowhere near having a problem yet. In order to qualify for supplemental O2 in the US, you must have sat levels below 88 either at rest or with activity. While your O2 levels were up and down, it doesn't sound as though you ever went below 90, and that's still in the normal range.

You may have aggravated things with the dust. Watch yourself over the next day or two, and if things begin to go south and it's clear that you've got something respiratory, see your doc ASAP. The thing you DON'T want is to get really sick; that can do more damage to your lungs and you can't recover from that. Wear a mask the next time you try to do something like this. That will protect you from the dust.

From john I’m on 92 witch is good for me when I’m on oxygen at night I’m up to 97 keep saying this buy a small fan it will push the air down you will breath better good luck

Pursed lip breathing is one technique that works to help blow off the CO2 that you build up during exertion. My suggestion, and what I do, is do it all the time, but do it before you start something with great exertion. It does help to keep you O2 levels up or raise them if you need to, but it also increases the time before they start to drop with activity, so if you start using the technique at the beginning, it take a lot longer for you to become sob which you're doing the activity. Also remember than as long as your O2 levels are good during the activity, you can keep going no matter how sob you get and you won't do any harm. That part's really good for you as it helps make your lungs become more efficient.
