Wheezing sound in lungs4/11/2024 ![]() ![]() Now if you happen to walk into a cloud of something that's toxic, your body is going to respond instantly to try to protect you. And those bronchioles are where the wheezing happens. It's almost like a tree's branches branching out. And from there they break into a whole bunch of little, smaller bronchioles. When you breathe in, the air comes through your nose or mouth, through the big windpipe and breaks into 2 big bronchi, one into each lung. Well to understand that, first let's all take a deep breath together (inhales). Alan Greene and I want to talk with you for a moment about how to tell the difference, what causes wheezing anyway, and when is it healthy and when is it not. Wheezing can be a normal healthy response to an unhealthy environment. And that hard breathing through a narrow passageway is what creates the sound we know as wheezing. You have to work to breathe, especially to breath out. The problem with that is when your bronchioles are constricted and swollen and has mucus in them, that narrow little opening is hard to breathe through. When they're hyper-alert and they respond to something that's not truly dangerous. Asthma happens when your airways are hyper-responsive. ![]() And if it's still there, still irritating, mucus will begin to be secreted to be able again to capture and protect you from those toxins. Inflammatory stuff to help protect you from those toxins. If that toxic cloud is still there, to protect your delicate tissues deep in your lungs, swelling of the lining will happen. The first thing that will happen is the muscles around the bronchioles will tighten, will constrict down almost like a boa constrictor, and you get the tight airways. ![]() Other tests can be used to assess the state of your lungs and to try to determine what the underlying cause of your bronchiectasis may be.Wheezing can be a normal healthy response to an unhealthy environment. If the scan shows that a section of airways is actually getting wider, this usually confirms bronchiectasis. In a healthy pair of lungs, the bronchi should become narrower the further they spread into your lungs, in the same way a tree branch separates into narrower branches and twigs. This produces a very detailed picture of the inside of your body, and the airways inside your lungs (the bronchi) should show up very clearly. ![]() Further testing HRCT scanĬurrently, the most effective test available to diagnose bronchiectasis is called a high-resolution CT (HRCT) scan.Ī HRCT scan involves taking several X-rays of your chest at slightly different angles. A computer is then used to put all the images together. If the GP suspects you could have bronchiectasis, you'll be referred to a doctor who specialises in treating lung conditions (a respiratory consultant) for further testing. If the GP thinks you may have a lung infection, they may take a sample of your phlegm so it can be checked for bacteria. You'll also probably have a chest X-ray to rule out other, more serious, causes of your symptoms, such as lung cancer. The lungs of people with bronchiectasis often make a distinctive crackling noise as a person breathes in and out. They may also listen to your lungs with a stethoscope as you breathe in and out. The GP will ask you about your symptoms, such as how often you cough, whether you bring up any phlegm (sputum), and whether you smoke. You should see a GP for advice if you develop a persistent cough so they can look for a possible cause. ![]()
