An oropharyngeal airway (also known as an oral airway, OPA or Guedel pattern airway) is a medical device called an airway adjunct used in airway management to maintain or open a patient's airway. It does this by preventing the tongue from covering the epiglottis, which could prevent the person from breathing. When a person becomes unconscious ...
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.
At each division point or generation, one airway branches into two smaller airways. The human respiratory tree may consist on average of 23 generations, while the respiratory tree of the mouse has up to 13 generations. Proximal divisions (those closest to the top of the tree, such as the bronchi) mainly function to transmit air to the lower ...
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.
It lies inferior to the epiglottis and extends to the location where this common pathway diverges into the respiratory and digestive pathways. At that point, the laryngopharynx is continuous with the esophagus posteriorly. The esophagus conducts food and fluids to the stomach; air enters the larynx anteriorly.

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]
