Fluid in the lungs: Doctors listen for absent or decreased breath sounds to determine if you have fluid blocking your breathing, which can be caused by pneumonia, heart failure, and pleural effusion. Rhonchi, a snoring-like sound: This sound occurs when air is blocked or inhibited through your large airways.
The stethoscope is used as first line diagnostic tool in assessment of patients with pulmonary symptoms.
Doctors can hear the tell-tale sounds of a leaky valve and pinpoint which valve is leaking and the amount of blood leaking. Arrhythmias. Physicians can hear if the patient has a normal heart rhythm or if the patient has an abnormal rhythm, called an arrhythmia, like atrial fibrillation.
For example, stethoscopes are especially good at hearing a heart murmur, a sign of a possibly abnormal heart valve. When listening to the lungs with a stethoscope, a doctor can diagnose diseases such as pneumonia, asthma, collapsed lungs or congestive heart failure. A stethoscope also is used to take blood pressure.
Lung auscultation
Your healthcare provider will first place a stethoscope on your chest. They'll move the stethoscope to different auscultation points on your chest. They'll start at the top of your lungs and move downward. They'll compare the sounds of each lung.

A heart murmur is a whooshing or swishing sound heard through a stethoscope when blood flows abnormally over your heart valves. Heart murmurs are common and don't necessarily indicate a health problem, especially in children.
Your GP should be able to diagnose you based on your symptoms and by listening to your chest using a stethoscope (a medical instrument used to listen to the heart and lungs). In some cases, further tests – such as a chest X-ray, breathing tests and testing phlegm or blood samples – may be needed.
The smart stethoscope accurately screened for heart failure 9 out of 10 times. Its sensitivity and specificity were similar to previous studies using a standard ECG machine. The researchers say this could allow primary care clinicians to detect heart failure earlier.
We use our stethoscope to listen to your lungs in different places on your chest and back, checking for things like infection or fluid in the lungs, or wheezing, which is caused by an abnormal tightness the tubes that bring air into the lungs (called bronchi).
Your doctor will also instruct you to take deep breaths while they listen. Deep breaths use the entire lung and thus provide more information if something's going on deep inside. They're looking for abnormal sounds, which can point to a potential health problem.
Your doctor can tell that you have pneumonia and not just a cold by listening with a stethoscope for crackle sounds in your chest. You may need a chest x-ray or blood tests to know for sure that you have pneumonia. If bacteria caused your pneumonia, your doctor can give you antibiotics, drugs that kill bacteria.
What is spirometry? A spirometry test measures how healthy your lungs are and can be used to help diagnose and monitor lung conditions. During the test, you will breathe out as much air as you can, as hard as you can, into a device called a spirometer.
With their stethoscope pressed against your chest, your healthcare provider will tap on your chest and listen for a hollow sound. If they hear a hollow sound, that means your lungs are trapping air. They'll then order tests to confirm emphysema.
Physical exam. Your doctor will listen to your lungs with a stethoscope. If you have pneumonia, your lungs may make crackling, bubbling, and rumbling sounds when you inhale.
Your doctor can diagnose bronchitis by assessing your symptoms as well as listening to your chest with a stethoscope for the rattling sound in your lungs which accompanies bronchitis.
Rhonchi. Rhonchi sounds have a continuous snoring, gurgling, or rattle-like quality. Rhonchi occur in the bronchi as air moves through tracheal-bronchial passages coated with mucus or respiratory secretions. This is often heard in pneumonia, chronic bronchitis, or cystic fibrosis.
Normal lung or vesicular breath sound: A doctor can hear this sound over most of the chest with a stethoscope, a device for listening to a person's internal body sounds. Vesicular breath sounds occur when air flows into and out of the lungs during breathing. The sound is soft, low pitched, and rustling in quality.
A heart murmur is a blowing, whooshing, or rasping sound heard during a heartbeat. The sound is caused by turbulent (rough) blood flow through the heart valves or near the heart.
Crackles. These may be either coarse or fine. They are discontinuous, interrupted explosive sounds. Coarse crackles or crepitations are associated with bronchiectasis or resolving pneumonia, whereas fine crackles can be heard with either pulmonary oedema or interstitial fibrosis.
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. Coarse crackles are more typical of COPD and present as prolonged, low pitched sounds. Fine crackles are more high pitched.
Bibasilar crackles can result from a severe lung problem. Prompt diagnosis and treatment may help to prevent long-term complications. Anyone who experiences bibasilar crackles and shortness of breath, chest pain, or blood-tinged mucus should seek immediate medical attention.
