Direct vision laryngoscopes – Student Zone

Direct vision laryngoscopes

Laryngoscopes are used to aid tracheal intubation and the placement of endotracheal tubes. They allow visualisation of the larynx and are used not only in operating theatres but ITU and A&E. They can also be used to visualise the larynx for suctioning, removal of a foreign body and placing nasogastric tubes and throat packs.
This module covers conventional or direct laryngoscopes. Video laryngoscopes and fibreoptic intubation are covered in different modules.


Anaesthetic machines back to front – Student Zone

Anaesthetic machines back to front

The most important piece of equipment that the anaesthetist uses is the anaesthesia machine. The basic function of an anaesthesia machine is to prepare a gas mixture of precisely known, but variable composition. The gas mixture can then be delivered to a breathing system. The anaesthesic machine itself has evolved from a simple pneumatic device to a complex array of mechanical, electrical and computer–controlled components. This module breaks down the essential features of the anaesthetic machine into its parts, explaining their purpose as it goes.


Endotracheal tubes – Student Zone

Endotracheal tubes

An endotracheal tube (ETT) is inserted into the trachea for the primary purpose of establishing and maintaining a definitive patent airway and to ensure the adequate exchange of oxygen and carbon dioxide. It is the gold standard for securing an airway, allowing positive-pressure ventilation while preventing contamination of the lungs from the contents of the pharynx and stomach.
