“…Depending on the level of inspiration, the posterior wall of the trachea becomes flat, convex or slightly concave. [ 13 14 ] The posterior wall of the trachea either flattens or bows slightly forward during expiration. In normal subjects, there is up to 35% reduction in antero-posteior tracheal lumen in forced expiration, whereas the transverse diameter decreases only by 13%.…”

Anatomy and physiology of respiratory system relevant to anaesthesia

Clinical application of anatomical and physiological knowledge of respiratory system improves patient's safety during anaesthesia. It also optimises patient's ventilatory condition and airway patency. Such knowledge has influence on airway management, lung isolation during anaesthesia, management of cases with respiratory disorders, respiratory endoluminal procedures and optimising ventilator strategies in the perioperative period. Understanding of ventilation, perfusion and their relation with each other is important for understanding respiratory physiology. Ventilation to perfusion ratio alters with anaesthesia, body position and with one-lung anaesthesia. Hypoxic pulmonary vasoconstriction, an important safety mechanism, is inhibited by majority of the anaesthetic drugs. Ventilation perfusion mismatch leads to reduced arterial oxygen concentration mainly because of early closure of airway, thus leading to decreased ventilation and atelectasis during anaesthesia. Various anaesthetic drugs alter neuronal control of the breathing and bronchomotor tone.

“…The posterior wall appears thinner and gives a variable contour to the shape of the trachea due to lack of cartilage. It may appear flat, convex or slightly concave depending on the level of inspiration [1,3,4] . The posterior wall of the trachea either flattens or bows slightly forward during expiration.…”

Recent state-of-the-art computed tomography and improved three-dimensional (3-D) postprocessing techniques have revolutionized the capability of visualizing airway pathology, offering physicians an advanced view of pathology and allowing for appropriate management planning. This article is a comprehensive review of trachea and main bronchi imaging, with emphasis on the dynamic airway anatomy, and a discussion of a wide variety of diseases including, but not limited to, congenital large airway abnormalities, tracheobronchial stenoses, benign and malignant neoplasms and tracheobronchomalacia. The importance of multiplanar reconstruction, 3-D reconstruction and incorporation of dynamic imaging for non-invasive evaluation of the large airways is stressed.

“…The bronchi pass in front of the descending aorta, and their positions in relation to the pulmonary vessels are variable based on the laterality. 3 The pulmonary trunk arises from the right ventricle of the heart and initially progresses anteriorly and then posterolaterally on the left side of the ascending aorta. At the level of the aortic arch, the pulmonary trunk bifurcates into the right and left pulmonary arteries.…”

The thoracic cavity contains vital cardiovascular and pulmonary structures. Few congenital anatomical variations in the bronchial tree and pulmonary vasculature have been reported. Understanding such variants is crucial during surgical procedures that involve the thorax. During routine dissection of an 89-year-old male cadaver as part of a first-year anatomy course, an anomaly of the bronchial tree was discovered. The left lung hilum was notable for the pulmonary artery being posterior to the mainstem bronchus. The case report describes normal lung development and anatomy and the significance of this novel variation in which has not been previously described in the literature.
