![]() In addition, normal BRONCHIAL sounds should ONLY be heard over the trachea and the bronchi.ĪBNORMAL BREATH SOUNDS, also known are ADVENTITIOUS and include the undesirable variations: CRACKLES WHEEZING STRIDOR SILENT CHEST PLEURAL FRICTION RUBĬRACKLES: (they sound like rice krispies) also known as RALES can indicate fluid or secretions (mucus) Often a clinician will say the patient sounds “wet”. The movement of the air should be low pitched quiet breathing, without any high pitched sounds or crackling. This should include all lung fields including the periphery or the lung borders. ![]() NORMAL BREATH SOUNDS, also known as VESICULAR, should be equal or BILATERAL over both lung fields. And that hard breathing through a narrow passageway is what creates the sound we know as wheezing.So what is the therapist hearing? First, let’s define the basics of Normal vs. 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. 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.
