The insertion of a tracheal tube can cause an infection in the trachea which then colonises and spreads to the bronchi. If there is further spread and development into the lungs this will give rise to ventilator-associated pneumonia. Antibiotics are recommended to prevent this development but only as a short term measure as antibiotic ...
The trachea is the largest tube in the respiratory tract and consists of tracheal rings of hyaline cartilage. It branches off into two bronchial tubes, a left and a right main bronchus . The bronchi branch off into smaller sections inside the lungs, called bronchioles .
The lower respiratory tract consists of the trachea (windpipe), bronchial tubes, bronchioles, and the lungs. [6] Lower respiratory tract infections (LRIs) are generally more severe than upper respiratory infections. LRIs are the leading cause of death among all infectious diseases. [7] The two most common LRIs are bronchitis and pneumonia. [8]
The trachea (pl.: tracheae or tracheas), also known as the windpipe, is a cartilaginous tube that connects the larynx to the bronchi of the lungs, allowing the passage of air, and so is present in almost all animals lungs. The trachea extends from the larynx and branches into the two primary bronchi.
[3] [15] The trachea and bronchi have plexuses of lymph capillaries in their mucosa and submucosa. The smaller bronchi have a single layer of lymph capillaries, and they are absent in the alveoli. [16] The lungs are supplied with the largest lymphatic drainage system of any other organ in the body. [17]
This, he explains, impairs the immune system and can lead to a bacterial "superinfection." Dr. Melamed says that coughing, fever, chills and muscle aches are all common symptoms of pneumonia.
Pneumonia may develop complications such as a lung abscess, a round cavity in the lung caused by the infection, or may spread to the pleural cavity. [ citation needed ] Poor oral care may be a contributing factor to lower respiratory disease, as bacteria from gum disease may travel through airways and into the lungs.
The respiratory system (also respiratory apparatus, ventilatory system) is a biological system consisting of specific organs and structures used for gas exchange in animals and plants. The anatomy and physiology that make this happen varies greatly, depending on the size of the organism, the environment in which it lives and its evolutionary ...
