Structure and Function of the Tracheobronchial System
نویسنده
چکیده
The tracheobronchial tree delivers and distributes air within the lung. Normally it provides a low resistance to airflow. Airway smooth muscle, the mucociliary system, the bronchial circulation, and cough provide neurally mediated protection of the lung from environmental challenges. Disease involves an exaggerated response of these mechanisms so that the airways become obstructed, distribution of ventilation is abnormal, and hypoxemia develops.

متن کاملVerification of an Evolutionary-based Wavelet Neural Network Model for Nonlinear Function Approximation
Nonlinear function approximation is one of the most important tasks in system analysis and identification. Several models have been presented to achieve an accurate approximation on nonlinear mathematics functions. However, the majority of the models are specific to certain problems and systems. In this paper, an evolutionary-based wavelet neural network model is proposed for structure definiti...
متن کاملManagement of Laryngotracheal and Tracheobronchial Injuries
Laryngotracheal and tracheobronchial injuries are uncommon, and their successful diagnosis and management often require a high level of expertise. This paper aimed at retrospective analysis of a thoracic surgeon's experience in the diagnosis and management of traumatic injuries to the larynx, trachea and major bronchi. Forty one patients with major airway trauma were managed from March 1994 to ...

متن کاملINTRAMURAL TRACHEOBRONCHIAL REMNANTS: A MISDIAGNOSED CAUSE OF CONGENITAL ESOPHAGEAL STENOSIS
In cases of congenital esophageal stenosis due to tracheobronchial remnants, symptoms of partial esophageal obstruction appear at the time of weaning or during early childhood. In the absence of esophagitis, esophagram combined with cinefluoroscopy demonstrates fixed stenosis of distal esophagus and appears to be diagnostic. Dilatation of rigid stenosis is invariably unrewarding and surgic...
