The oropharyngeal airway was designed by Arthur Guedel. [2]Oropharyngeal airways come in a variety of sizes, from infant to adult, and are used commonly in pre-hospital emergency care and for short term airway management post anaesthetic or when manual methods are inadequate to maintain an open airway.
An oropharyngeal or nasopharyngeal airway is used during bag-valve-mask ventilation to prevent soft tissues from blocking the airway. An oropharyngeal airway may cause gagging and vomiting. Therefore, an oropharyngeal airway must be sized appropriately. An airway that is incorrectly sized can worsen the airway obstruction.
Airway obstruction is commonly caused by the tongue, the airways itself, foreign bodies or materials from the body itself, such as blood or vomit. [ 2 ] Contrary to advanced airway management , basic airway management technique do not rely on the use of invasive medical equipment and can be performed with less training.
A model of an oropharyngeal airway (OPA) preventing the tongue from obstructing the airway. An oropharyngeal airway (OPA) is a rigid tube that is inserted into the mouth through the oropharynx and placed above the tongue to move it away from the back of the throat. [2] [4] They are more commonly used than nasopharyngeal airways (NPAs). [4]
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.
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.

People with significant underlying disease or injury are at greater risk for developing respiratory complications following pulmonary aspiration, especially hospitalized patients, because of certain factors such as depressed level of consciousness and impaired airway defenses (gag reflex and respiratory tract antimicrobial defense system ...
