![]() Sometimes, wheezing can be loud enough to hear without a stethoscope. Wheezing: Wheezing noises are high-pitched and continuous and may sound like a breathy whistle.Crackling breath sounds may sound wet or dry, and doctors might describe them as either fine or coarse. Crackles: Also called rales, crackles tend to sound like discontinuous clicking, rattling, or bubbling when the person inhales.There are several distinct types of abnormal breath sounds, including: Infections and other conditions that cause inflammation or fluid buildup in the lungs commonly cause unusual breath sounds. These sounds are more apparent with a stethoscope, but some are loud enough to hear with the ears.Ībnormal breathing may be a sign of an underlying issue or medical condition. However, abnormal breaths may sound strained, and odd noises may come from the lungs when the person inhales or exhales. The normal sounds that people make when they breathe should hardly be noticeable. These coarse crackles are caused by the movement of boluses of gas through an intermittently occluded airway.Breath sounds, also called lung sounds, are the noises that the structures in the lungs make when a person breathes in and out. Geeky bit: coarse crackles are caused by gas moving through an intermittently obstructed airway ![]() Your patient may have a degree of mucus plugging, if they cough, the crackle might disappear, so don’t be alarmed by this in your exam (or in hospital) if you get different findings to other people. These have a “ popping” quality and should be heard over the whole chest. You might be able to hear coarse crackles at the beginning of inspiration (most of the time you can also hear this during expiration). When you listen to the chest breath sounds can be diminished and expiration is prolonged. Please remember COPD is NOT a cause of clubbing! In COPD patients you will see on observation: ‘barrel shaped chest’, shortness of breath, pursed lips breathing, inhalers on the side table and coughing Use all the clues in the room to help you. If I can give one piece of advice it’s this. I know this tutorial is about auscultation sounds, but we might as well throw in some Respiratory OSCEs tips whilst you’re here. We are going to assume that you know how to do a respiratory examination and we’ll just focus on the exciting bits.Ĭhronic obstructive pulmonary disease (COPD) In reality there are only a number of stations that can come up in your OSCEs and we are going to cover them all. We are going to run through everything you need to know to snatch top marks in your respiratory examination stations by focusing on auscultation sounds. And then blurt out something that sounds kind of right?Įxamination stations are a gift as you can practice exactly what you are going to get in the exam! As they stand trying to figure out the difference between fine inspiratory crackles, wheeze, coarse crackles, reduced air entry. Coarse crackles = low pitched, high amplitude, long durationĪ phase that drives fear into most medical students hearts.Discontinuous Fine crackles = fine, high pitched, low aptitude, short duration.
