The complex of these measures includes clearing the airways, maintaining free access of the oxygen mixture using special devices, and providing respiratory support measures.
A medical air duct is a hollow tube of a curved configuration made of a polymer material. It has a special shape that ensures easy passage of the air mixture into the patient’s respiratory canals, preventing tongue retraction and the occurrence of asphyxia during surgical operations under general anesthesia. In addition, it is used during artificial respiration procedures.
Depending on the material of manufacture and design, air ducts are divided into three classes:
Tracheotomy tubes belong to the category of reusable medical instruments. They are made of stainless medical steel and can be disinfected and sterilized. The tube is inserted into the incision in the wall of the trachea, providing a flow of fresh air into the patient's lungs. At the end of the tube there is a special connector with which it is connected to a ventilator. A special cuff and valve may be placed on the end of the tube, which allows the patient to talk;
An endotracheal tube or endotracheal tube is a flexible tubular medical device that is used for tracheal intubation, insertion of a bronchoscope, catheters, supply of respiratory mixture, and administration of inhalation anesthetics. It is flexible, has a small diameter and may have a protective cuff at the end. Endotracheal tubes are used in anesthesiology, in intensive care and resuscitation departments.
