Stridor is caused by something blocking the larynx, such as a person choking on an object. Air is moving roughly over a partially obstructed upper airway. When listening with a stethoscope, if the sound is louder over the throat, it is stridor, not wheezing. Stridor is a high-pitched musical sound heard on inspiration, which resembles wheezing. This is often heard in pneumonia, chronic bronchitis, or cystic fibrosis. Rhonchi occur in the bronchi as air moves through tracheal-bronchial passages coated with mucus or respiratory secretions. Rhonchi sounds have a continuous snoring, gurgling, or rattle-like quality. Listen to the following wheezing lung sounds:Ī wheeze may also be lower-pitched, having a snoring or moaning quality in which they are referred to as rhonchi. The classic wheeze refers to the high-pitched whistle-like sound heard during exhalation as air moves through a narrow or obstructed airway. Wheezing sounds may occur during inhalation or exhalation and are continuous with a musical quality. Wheezing is caused by the narrowing of the airways and is associated with asthma, bronchitis, pneumonia, COPD, smoking, heart failure, inhaling a foreign object into the lungs, or an allergic reaction. Types of abnormal breath sounds include wheezing, rhonchi (which sound like low-pitched wheezing), stridor, crackles (also known as rales, and these may be further classified as fine or coarse), and pleural friction rub. The lung sounds are classified according to the sounds involved during inhalation and exhalation phases of the breath cycle, taking note of the pitch and intensity. These are easily identified by auscultation, or listening to the lungs fields with the stethoscope. Tuberculosis A chronic bacterial disease, caused by Mycobacterium tuberculosis, that usually affects the lungs but can also affect other organs such as the brain and kidneys it is spread by cough and can lie dormant in a person's lungs for decades and then reactivate.Hi, and welcome to this video on lung sounds! Lung sounds, or breath sounds, refer to the sounds heard when air moves through the respiratory system. Influenza type A Virus that has crossed the animal/human barrier and has infected humans, recently reaching a pandemic level with the H1N1 strain. Pertussis An airborne bacterial infection that affects mostly children younger than 6 years, in which the patient is feverish and exhibits a "whoop" sound on inspiration after a coughing attack highly contagious through droplet infection. factors that predispose a patient to pneumonia: -nursing home facility -recent hospitalization -chronic disease processes -immune system compromise -history of COPD Treatment includes airway support and providing supplemental oxygen. Pneumonia is often a secondary infection and begins after an upper respiratory tract infection such as a cold or sore throat. Pneumonia An infectious disease of the lung that damages lung tissue its cause can be bacterial, viral, or fungal. Bronchiolitis Inflammation of the bronchioles that usually occurs in children younger than 2 years and is often caused by the respiratory syncytial virus (RSV). respiratory syncytial virus A virus that causes an infection of the lungs and breathing passages can lead to other serious illnesses that affect the lungs or heart, such as bronchiolitis and pneumonia highly contagious and spread through droplets. Caused most often by bacterial infection. Responds well to humidified oxygen Epiglottitis A disease in which the epiglottis becomes inflamed and enlarged and may cause an upper airway obstruction. Croup An inflammatory disease of the upper respiratory system that may cause a partial airway obstruction and is characterized by a barking cough usually seen in children.
