A bronchopulmonary segment is a portion of lung supplied by a specific segmental bronchus and its vessels. [ 1 ] [ 2 ] These arteries branch from the pulmonary and bronchial arteries , and run together through the center of the segment.
The lobar bronchi branch into tertiary bronchi also known as segmental bronchi and these supply air to the further divisions of the lobes known as bronchopulmonary segments. Each bronchopulmonary segment has its own (segmental) bronchus and arterial supply. [8] Segments for the left and right lung are shown in the table. [5]
Postural drainage is used to treat any condition that causes the build-up of secretions in bronchopulmonary segments. These include: bronchiectasis [2] [3] lung abscesses [2] [3] cystic fibrosis [3] atelectasis [3] chronic obstructive pulmonary disease (COPD) [3] pneumonia [3] postoperative lung damage (after some thoracic surgery) [3] COVID-19 [4]
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 ...
These lymph nodes form four main groups including paratracheal, tracheobronchial, bronchopulmonary and pulmonary nodes. Paratracheal nodes are located on either side of the trachea. Tracheobronchial nodes can be divided into three nodes including left and right superior tracheobronchial nodes, and the inferior trachiobronchial node. The two ...
Segmentectomies are the surgical removal of bronchopulmonary segments and often involve the removal of two adjacent segments. The pulmonary arterial branches to the segments are first identified then divided. Next, stapling is used to divide the segmental bronchi and separate the segments from the lung. [13]
A bronchus (/ ˈ b r ɒ ŋ k ə s / BRONG-kəs; pl.: bronchi, / ˈ b r ɒ ŋ k aɪ / BRONG-ky) is a passage or airway in the lower respiratory tract that conducts air into the lungs.The first or primary bronchi to branch from the trachea at the carina are the right main bronchus and the left main bronchus.
Medical diagnosis of pulmonary hypoplasia in utero may use imaging, usually ultrasound or MRI. [12] [13] The extent of hypoplasia is a very important prognostic factor. [14]One study of 147 fetuses (49 normal, 98 with abnormalities) found that a simple measurement, the ratio of chest length to trunk length, was a useful predictor of postnatal respiratory distress.
