This condition is most commonly seen in infants and young children. [2] The usual symptom is stridor when a person breathes out. This is usually known as a collapsed windpipe. The trachea normally opens slightly during breathing in and narrows slightly during breathing out. These processes are exaggerated in tracheomalacia, leading to airway ...
Stridor (from Latin 'creaking/grating noise') is an extra-thoracic high-pitched breath sound resulting from turbulent air flow in the larynx or lower in the bronchial tree. It is different from a stertor , which is a noise originating in the pharynx .
Respiratory sounds, also known as lung sounds or breath sounds, are the specific sounds generated by the movement of air through the respiratory system. [1] These may be easily audible or identified through auscultation of the respiratory system through the lung fields with a stethoscope as well as from the spectral characteristics of lung sounds.

Stridor is a high-pitched sound which occurs during breathing and is associated with obstruction at the level of the larynx. Difficulty swallowing and changes in voice are common symptoms. [ 3 ] If there is total obstruction, severe respiratory distress or cyanosis due to hypoxia (lack of oxygen in the blood) can occur.
Assess the patient to determine if other signs or symptoms of respiratory – retractions, wheezing, nasal flaring, grunting, etc. -- or cardiac – cyanosis, irritability, edema, etc. -- distress are present. If a child has any acute distress immediate medical intervention is needed. [18] Pediatric early warning score card
Productive vs. nonproductive cough You can further drill a cough down into a productive or nonproductive cough. “A productive cough is a cough that produces phlegm,” Dr. Youssef says.
Children often present with excessive drooling and stridor (high pitched breathing sounds). [3] Classic triad of choking symptoms in children is coughing, wheezing, and diminished breath sounds, however, a 10-year review showed that this grouping of symptoms was present together in only about 60% of patients. [14]
Stertor (from Latin stertere 'to snore') is a term first used in 1804 [2] to describe a noisy breathing sound, such as snoring. [3] [4] It is caused by partial obstruction of the upper airways, at the level of the nasopharynx or oropharynx. [1] It is distinguished from stridor by its pitch. [4]
