The right main bronchus is wider, shorter, and more vertical than the left main bronchus, [3] its mean length is 1.09 cm. [4] It enters the root of the right lung at approximately the fifth thoracic vertebra. The right main bronchus subdivides into three secondary bronchi (also known as lobar bronchi), which deliver oxygen to the three lobes of ...
In blunt chest trauma, TBI occurs within 2.5 cm of the carina 40–80% of the time. [2] The injury is more common in the right main bronchus than the left, possibly because the former is near vertebrae, which may injure it. [2] Also, the aorta and other tissues in the mid chest that surround the left main bronchus may protect it. [22]

The carina occurs at the lower end of the trachea - usually at the level of the 4th to 5th thoracic vertebra. [3] [4] This is in line with the sternal angle, but the carina may raise or descend up to two vertebrae higher or lower with breathing. The carina lies to the left of the midline, and runs antero-posteriorly (front to back). [citation ...
The right lung has three lobes – upper, middle, and lower (or superior, middle, and inferior), and the left lung has two – upper and lower (or superior and inferior), plus a small tongue-shaped portion of the upper lobe known as the lingula. Each lobe is further divided up into segments called bronchopulmonary segments. Each lung has a ...
The right paratracheal stripe is also important to assess, as it can reflect a process in the posterior mediastinum, in particular the spine or paraspinal soft tissues; normally it should measure 3 mm or less. The left paratracheal stripe is more variable and only seen in 25% of normal patients on posteroanterior views.
The double bronchial wall sign is best visualized on CT, which provides high-resolution images of the mediastinal structures. The double bronchial wall sign is commonly seen in the central bronchi, particularly in the trachea or mainstem bronchi, where air is more likely to outline the structures.
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. [2]
