Nasal flaring in young children; Seesaw breathing in infants (where the chest and abdomen "seesaw" up and down; this is a sign of severe respiratory distress in an infant) A child exhibiting decreased work of breathing may be bradypneic (breathing too slowly) or too weak to engage the muscles required for inhalation.
There are however certain infants with conditions such as choanal atresia in which deaths have resulted from nasal obstruction. [20] In these cases, there are cyclical periods of cyanosis. The infant initially attempts to breathe through the nose, and is unable to; hypercapnia occurs, and many babies instinctively begin to cry. While crying ...
Bronchoalveolar lavage (BAL), also known as bronchoalveolar washing, is a diagnostic method of the lower respiratory system in which a bronchoscope is passed through the mouth or nose into an appropriate airway in the lungs, with a measured amount of fluid introduced and then collected for examination.

Periodic breathing during sleep occurs typically in adult patients with congestive heart failure. Periodic breathing is also a normal variation of breathing found in premature and full term infants. It occurs when the infant has pauses in breathing for no more than 10 seconds at a time followed by a series of rapid, shallow breaths.
The medial nasal process (nasomedial) on the inner side of each nasal pit merge into the intermaxillary segment and form the upper lip, crest, and tip of the nose. [1] The medial nasal processes merge with the maxillary prominences. The lateral nasal process from each side merge to form the alae of the nose. [1]
Saddle nose is a condition associated with nasal trauma, congenital syphilis, relapsing polychondritis, granulomatosis with polyangiitis, cocaine abuse, and leprosy, among other conditions. [1] The most common cause is nasal trauma. It is characterized by a loss of height of the nose, because of the collapse of the nasal bridge. The depressed ...
The behavior of sniffing incorporates changes in air flow within the nose.This can involve changes in the depth of inhalation and the frequency of inhalations. Both of these entail modulations in the manner whereby air flows within the nasal cavity and through the nostrils.
