Along with your symptoms, your breathing can tell your healthcare team more about your chronic obstructive pulmonary disease (COPD). COPD refers to is a group of progressive lung diseases that make it harder for you to breathe. Show Lung sounds can give your doctor clues about the state of your airways and can help them determine whether your treatment is working. Keep reading to understand more about what your healthcare team is listening for when it comes to lung sounds. Wheezing is a high-pitched whistling sound. If a healthcare professional hears wheezes in only one area, it may be due to a blockage. With COPD, however, wheezes are more likely to be heard throughout your lungs and airways. The inflammation that comes with COPD can affect both your large and small airways by causing them to narrow. A wheezing sound is the vibration of air through these narrowed airways. This wheezing sound can sometimes be heard when you breathe in. In most cases, though, it’s louder when you’re breathing out. Crackles, previously called rales, refer to a noise that’s:
A healthcare professional can listen to this sound using a stethoscope, and it’s most likely to be heard when you breathe in. Crackling is the sound that’s made when small air bubbles pass through fluid. This can indicate a buildup of mucous or pus in your airways. Coughing will temporarily dislodge the fluid, and the crackles go away. There are three different types of crackles:
Stridor is similar to wheezing, but the sound is typically louder than a wheeze. It can be identified when you breathe in or out — or both — and can identify upper airway blockages or narrowing. If stridor is heard when you breathe in, it means there’s a narrowing or blockage above your voice box, called the larynx. If the sound is heard when you breathe out, it means there’s a narrowing in your trachea, or windpipe. The trachea is the tube that connects your throat to your lungs. A rhonchus is a continuous sound that may be heard in the lungs. It’s a lower-pitched sound than a wheeze. Through a stethoscope, it sounds similar to snoring. This can indicate a buildup of fluid in the larger airways. In COPD, rhonchi can mean an increase in fluids is being secreted by the airways. Hamman’s sign is a crackling or crunching sound that occurs at the same time as your heartbeat. It happens when air gets trapped in the space between your lungs, called the mediastinum. Air doesn’t typically leak into this area. If your doctor detects Hamman’s sign, it means there’s been damage to your lungs or windpipe, which is causing air to escape. A whooping sound can happen with coughing when a person is gasping for air. It’s the high-pitched sound of air rushing into your airways. This sound is often heard in pertussis, also known as whooping cough. Pertussis is caused by a bacteria. People with COPD are at greater risk of contracting pertussis. Pertussis can cause COPD symptoms to flare. Many people are successfully protected from pertussis with vaccination. Talk with your doctor to make sure your immunizations are up to date. Your lungs and lung cavity are covered by thin membranes called pleurae. Typically, they slide smoothly over each other to regulate breathing. A pleural friction rub is a quick, explosive sound. It can be heard when you breathe in or out. It’s a sign that something is interrupting the membranes. In COPD, this sound is often due to inflammation. A healthcare professional can hear lung sounds with a stethoscope. Some can be detected even without a stethoscope. To investigate further, your healthcare team might call for the following tests:
Treatments are available to manage the signs and symptoms of COPD. These include:
Listening to your lungs and airways can provide your doctor with a lot of information about what’s going on inside your body. Certain sounds can indicate narrowing in your airways or fluid buildup. Your healthcare team may require further testing to find out more. What lung sounds are heard with emphysema?Crackling. Crackling , otherwise known as rales, describes a sound in the lungs that resembles a crackling or clicking sound when a person breathes in. According to one 2021 study, crackling sounds are common in COPD. There are two distinct types of crackling sounds detectable in the lungs: coarse and fine.
What percussion sounds will you hear in patient with COPD in?The percussion sound is hyperresonant, if the sound is more hollow than normal. [75] The characteristic finding in COPD is a generalized and symmetrical hyperresonance note.
What are the expected assessment findings with emphysema?Findings on general physical examination can be cyanosis, tachypnea, use of accessory respiratory muscles, paradoxical indrawing of lower intercostal spaces is evident (known as the Hoover sign), elevated jugular venous pulse and peripheral edema.
What is the typical appearance of a patient with emphysema?When emphysema develops, the alveoli and lung tissue are destroyed. With this damage, the alveoli cannot support the bronchial tubes. The tubes collapse and cause an “obstruction” (a blockage), which traps air inside the lungs. Too much air trapped in the lungs can give some patients a barrel-chested appearance.
