The Combitube—also known as the esophageal tracheal airway or esophageal tracheal double-lumen airway—is a blind insertion airway device (BIAD) used in the pre-hospital and emergency setting. [1] It is designed to provide an airway to facilitate the mechanical ventilation of a patient in respiratory distress .
Airway management can be classified into closed or open techniques depending on the system of ventilation used. Tracheal intubation is a typical example of a closed technique as ventilation occurs using a closed circuit. Several open techniques exist, such as spontaneous ventilation, apnoeic ventilation or jet ventilation.
While Mallampati classes I and II are associated with relatively easy intubation, classes III and IV are associated with increased difficulty. A systematic review of 42 studies, with 34,513 participants, found that the modified Mallampati score is a good predictor of difficult direct laryngoscopy and intubation, but poor at predicting difficult ...
An oropharyngeal airway is acceptable, however nasopharyngeal airways should be avoided in trauma, particularly if a basilar skull fracture is suspected. [42] Endotracheal intubation carries with it many risks, particularly when paralytics are used, as maintenance of the airway becomes a challenge if intubation fails.
Tracheal intubation, often simply referred to as intubation, is the placement of a flexible plastic or rubber endotracheal tube (ETT) into the trachea to maintain an open airway, allow for effective ventilation, protect the airway from aspiration (when a cuffed ETT is used), and to serve as a conduit through which to administer inhaled anesthetics.
Oropharyngeal airways are one of several different blind insertion airway devices. A blind insertion airway device (BIAD or blind insertion device) is a medical device used for airway management that ensures an open pathway between a patient's lungs and the outside world, as well as reducing the risk of aspiration, which can be placed without visualization of the glottis.

The Simplified Airway Risk Index (SARI), or El-Ganzouri Risk Index (EGRI), is a multivariate risk score thought to estimate the risk of difficult tracheal intubation. The SARI score ranges from 0 to 12 points, where a higher number of points indicates a more difficult airway. A SARI score of 4 or above is thought to indicate a difficult ...
The process of forcing air into and out of the lungs is known as ventilation. The process by which oxygen is taken in by the bloodstream is called oxygenation. Lung compliance is the capacity of the lungs to contract and expand. The obstruction of airflow via the respiratory tract is known as airway resistance.
