This problem causes noisy or difficult breathing in the first 1 to 2 months after birth. This is called congenital tracheomalacia (it was present at birth). It is not very common. Babies born with tracheomalacia may have other health issues like a heart defect, reflux or developmental delay.
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 (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. Stridor is a physical sign which is caused by a narrowed or obstructed airway.
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]
Bronchomalacia means 'floppiness' of some part of the bronchi. Patients present with noisy breathing and/or wheezing. There is collapse of a main stem bronchus on exhalation. If the trachea is also involved the term tracheobronchomalacia (TBM) is used. If only the upper airway the trachea is involved it is called tracheomalacia (TM). There are ...
Catathrenia or nocturnal groaning is a sleep-related breathing disorder, consisting of end-inspiratory apnea (breath holding) and expiratory groaning during sleep.It describes a rare condition characterized by monotonous, irregular groans while sleeping. [1]
Laryngotracheal stenosis is an umbrella term for a wide and heterogeneous group of very rare conditions. The population incidence of adult post-intubation laryngotracheal stenosis which is the commonest benign sub-type of this condition is approximately 1 in 200,000 adults per year. [10] The main causes of adult laryngotracheal stenosis are:
Crackles are more common during the inspiratory than the expiratory phase of breathing, but they may be heard during the expiratory phase. Crackles are often described as fine, medium, and coarse. They can also be characterized as to their timing: fine crackles are usually late-inspiratory, whereas coarse crackles are early inspiratory.
