A tracheostomy tube may be single or dual lumen, and also cuffed or uncuffed. A dual lumen tracheostomy tube consists of an outer cannula or main shaft, an inner cannula, and an obturator. The obturator is used when inserting the tracheostomy tube to guide the placement of the outer cannula and is removed once the outer cannula is in place.
A tracheotome is a medical instrument used to perform an incision in the trachea with a cutting blade operated by a powered cannula. It is often called a tracheostomy tube because once it enters the stoma in the trachea, a breathing tube is connected to a ventilator and oxygen is provided to the lungs.
Tracheostomy — When patients require mechanical ventilation for several weeks, a tracheostomy may provide the most suitable access to the trachea. A tracheostomy is a surgically created passage into the trachea. Tracheostomy tubes are well tolerated and often do not necessitate any use of sedative drugs.
In a nasotracheal procedure, an endotracheal tube is passed through the nose and vocal apparatus into the trachea. Other methods of intubation involve surgery and include the cricothyrotomy (used almost exclusively in emergency circumstances) and the tracheotomy, used primarily in situations where a prolonged need for airway support is anticipated.
Early tracheostomy devices are illustrated in Habicot's Question Chirurgicale [21] and Julius Casserius' posthumous Tabulae anatomicae in 1627. [23] Thomas Fienus (1567–1631), Professor of Medicine at the University of Louvain, was the first to use the word "tracheotomy" in 1649, but this term was not commonly used until a century later. [24]
Cricothyrotomy is used as emergency surgical access due to being fast and simple. Another surgical airway method is called tracheostomy. Tracheostomy is done in the operating room by a surgeon. This is the preferred method for patients requiring long-term ventilation. Tracheostomy uses skin puncture and dilators to insert the tracheostomy tube ...

In an emergency, or when tracheal intubation is deemed impossible, a tracheotomy is often performed to insert a tube for ventilation, usually when needed for particular types of surgery to be carried out so that the airway can be kept open. The provision of the opening via a tracheotomy is called a tracheostomy. [19]
