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.
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.

Cheyne–Stokes respiration is a breathing pattern consisting of alternating periods of rapid and slow breathing, which may result from a brain stem injury. [12] Cheyne-Stokes respiration may be observed in newborn babies, but this is occasionally physiological (normal). Chest retractions may be observed in patients with asthma.
Transient tachypnea of the newborn is a respiratory problem that can be seen in the newborn shortly after delivery. It is caused by retained fetal lung fluid due to impaired clearance mechanisms. [1] It is the most common cause of respiratory distress in term neonates.
Manifestations: Breathing patterns are often irregular and shallow. The infants respiration rate should be between 30 and 60 breaths per minute with preference for nasal breathing. Ribs expands horizontally. Breath sounds should be clear and equal in both lungs. Abdominal breathing is normal. Acrocyanosis is a normal finding. [1]

For example, high blood glucose levels, called hyperglycemia, can boost the number of breathing movements. Conversely, hypoglycemia can reduce the number of fetal breathing movements. Tobacco use is also known to lower fetal breathing rates. Fetal breathing may help tone the muscles in preparation for breathing movements once the fetus is born.
“These baby common snappers were recently spotted entering the world,” reads the caption from the U.S. Fish and Wildlife service. “Snapping turtles are typically born between August and October.
