What's asthma feel like? Easy to demonstrate... First, focus a bit on your breathing. See how much you inhale and exhale just sitting at your keyboards. No, James, we ain't meditating; come back here.. Ok, take a deep breathe and let it out; you go back to the lung volumes you started at. Lots of room for big breaths. OK, asthma attack. Another big breath, but only let out this much, he said,holding his fingers that much apart. LOL. Let out just a bit; this is your new baseline. Breathe normal from here. Not much room to go up,and no room for a really big breath. (Like trying to talk without exhaling after taking a hit, haha) The biggest problem with asthma isn't getting the air in, it's getting it out. When you breathe, your tubes get mechanically stretched a bit just by expansion of the lung tissue. Opposite happens with exhaling; tubes get a bit smaller. If you exhale forcefully, they become even more pinched. OK, so with asthma, they become too narrow to get all the air out before you take your next breath. It's called air trapping.( Plus tubes get blocked mucus plugs). Oh, and wheezes; there are 2 reasons why people don't wheeze... 1) Their tubes are all open. That's good 2)They aren't moving enuf air to create a wheeze. That is not good. In fact, that is very bad; I think the docs use a big word for that; "ominous".
