Types and causes of abnormal respiratory sounds

There are four main types of abnormal respiratory sounds:

1) Rales: are a soft rattle in the lungs that can be heard when someone takes a breath (inhales). A lesion is thought to occur when air enters previously closed air gaps. To further define the various qualities of rales, the term moist, dry, fine, or coarse is appropriate.

2) Rhonchi: Snoring-like sounds arise when the airways are obstructed, or airflow becomes turbulent.

3) Stridor: Breathing causes a wheeze-like sound because of a blockage in the windpipe (trachea) or in the posterior part of the throat, which constitutes the upper respiratory tract.

4) Wheeze: Intense high-pitched noises as a result of constricted airways, especially in the exhalation phase of respiration. It occurs due to constriction in the lower respiratory tract and is usually a sign of chronic bronchitis.

Many conditions can cause abnormal sounds to occur. They may occur in certain cases which are as follows:

1) Pneumonia

2) Chronic obstructive pulmonary disease (COPD)

3) Heart failure

4) Emphysema

5) Asthma

6) Infection in the lungs airways (upper respiratory infection/lower respiratory infection/ bronchitis)

Infections can occur in individuals allergic to pollen, dust mites, pets, mold spores, particles of cockroach waste. It usually causes the common cold.

Diagnosis and treatment of abnormal respiratory sounds
Health care specialists will review a patient’s past medical history to discover the root cause of irregular breath sounds. This includes all of the following: present or former medical issues and all prescription drugs.

Several tests are used to figure out what is creating the strange sound. They are as follows:

Computed tomography (CT) scan and chest X-ray (CXR).

Blood testing.

Pulmonary function test (PFT): Another test commonly done is a PFT, which measures the volume of inhaled and exhaled air as well as the functionality of the lungs.

The culturing of sputum: A sputum culture is a test to look for bacteria or fungi in the mucus of the lungs. For this test, the doctor will have you cough into a container. Afterward, the material is sent to a lab for further testing.

An extensive list of treatment options for aberrant breath sounds can be found, depending on the diagnosis. The symptoms are taken into consideration together with the source and level of the problem when it comes to therapy recommendations. Drugs are commonly used to combat infections or to alleviate breathing problems.

Inhaler for asthmatic patients
However, fluid can accumulate in the lungs or block the airways, and in these circumstances, hospitalization may be required. Doctors give breathing treatments to open the airways during asthma, COPD, or bronchitis. Some patients with asthma may be prescribed a drug that they need to use every day. Ailments related to asthma such as bronchitis, phlegm, and chest congestion can be prevented and/or decreased with regular use of this ingredient. The below picture shows the use of a respiratory inhaler.

Inhalers for treating asthma are the best way to administer asthma medicine into the lungs. The inhaler for asthma patients is available in two types. They are as follows:

1) Metered-dose inhaler: This type uses a small aerosol canister that pushes out a short burst of the medicine by the mouthpiece made up of plastic.

2) Dry powder inhaler: This type sprays the medicine when the patient takes a deep breath.
