Abstract Background Wheezes and crackles are well-known signs of lung diseases, but can also be heard in apparently healthy adults. Results Twenty-eight percent of individuals had wheezes or crackles. Conclusions Nearly over a quarter of adults present adventitious lung sounds on auscultation. Background Two hundred years after its invention, the relevance of the stethoscope in modern medical practice has become a topic of debate [ 1 , 2 ].

Questionnaires and examinations In the first visit, the participants filled a questionnaire that included questions on medical conditions such as arterial hypertension, heart failure, atrial fibrillation, COPD, asthma, among others.

One type of sound that can indicate a problem is called bibasilar crackles. The sounds of the lungs can provide clues that help a doctor to diagnose an underlying condition. In this article, learn about the conditions that cause bibasilar crackles. We also describe how a doctor diagnoses and treats them. Bibasilar crackles are abnormal sounds from the base of the lungs. They indicate that something is interfering with airflow.

Two issues often cause bibasilar crackles. One is the accumulation of mucus or fluid in the lungs. Another is a failure of parts of the lungs to inflate properly. The crackles sound like brief popping when a person breathes. Some people describe the sound as similar to wood burning in a fireplace. For example, fine crackles are often soft and high-pitched. Coarse crackles are usually louder and low-pitched, with a wet or bubbling sound.

Bibasilar crackles may occur with additional symptoms, depending on the underlying cause. Possible accompanying symptoms include:. Many conditions can cause bibasilar crackles, and they are usually based in the heart or lungs. Below are some potential causes of bibasilar crackles. Pneumonia is an infection in the lungs, which can result from a virus, bacteria, or fungus. The infection can cause shortness of breath, fatigue, and coughing, as well as bibasilar crackles.

In some cases, pneumonia can be life-threatening. According to the United States Centers for Disease Control and Prevention , pneumonia is the leading infectious cause of death in children under age 5 worldwide. Heart failure occurs when the heart is too weak to pump blood efficiently to the rest of the body.

If the heart is not working correctly, the blood does not exit the lungs as quickly as it should. This can cause fluid to build up, and it can pool in the lungs. Heart failure can affect both children and adults.

Heart failure affects approximately 5. Beyond bibasilar crackles, symptoms may include swelling in the abdomen, coughing, and shortness of breath. Have you ever wondered what your doctor is listening for when he puts a stethoscope against your back and tells you to breathe?

These sounds indicate something serious is happening in your lungs. Bibasilar crackles are a bubbling or crackling sound originating from the base of the lungs. They may occur when the lungs inflate or deflate.

Excess fluid in the airways causes these sounds. Depending on the cause, bibasilar crackles may occur with other symptoms. These symptoms can include:.

Pneumonia is an infection in your lungs. It may be in one or both lungs. The infection causes air sacs in your lungs to become pus-filled and inflamed. This causes a cough, difficulty breathing, and crackles. Pneumonia may be mild or life-threatening. Bronchitis occurs when your bronchial tubes become inflamed.

These tubes carry air to your lungs. The symptoms may include bibasilar crackles, a severe cough which brings up mucus, and wheezing. Viruses, such as the cold or flu, or lung irritants usually cause acute bronchitis. Smoking is the main cause of chronic bronchitis.

Pulmonary edema may cause crackling sounds in your lungs. People with congestive heart failure CHF often have pulmonary edema. CHF occurs when the heart cannot pump blood effectively. This results in a backup of blood, which increases blood pressure and causes fluid to collect in the air sacs in the lungs.

The interstitium is the tissue and space that surrounds the air sacs of the lung. Any lung disease that impacts this area is known as interstitial lung disease.

It may be caused by:. Although not as common, bibasilar crackles may also be present if you have chronic obstructive pulmonary disease COPD or asthma. A study showed that lung crackles may be related to age in some asymptomatic cardiovascular patients.

Although more research is needed, the study found that after the age of 45, the occurrence of crackles tripled every 10 years. Your doctor uses a stethoscope listens to you breathe and to listen for bibasilar crackles. Crackles make a similar sound to rubbing your hair between your fingers, near your ear.
