Oropharyngeal Airway OPA

An oropharyngeal airway (oral airway, OPA) is an airway adjunct used to maintain or open the airway by stopping the tongue from covering the epiglottis. In this position, the tongue may prevent an individual from breathing.

Product Description

Mainly used for unconscious patients after coma, prevent the tongue from falling back, block the airway, and keep the airway unobstructed.

Choose the appropriate model according to the specific situation of the patient, and measure the length of the line connecting the corner of the patient's mouth to the mandibular angle behind the ear

The safer method is to choose a larger size oropharyngeal airway.


1. Direct placement: Using a tongue retractor or a tongue depressor as an auxiliary tool, the pharyngeal bend of the ventilation tube is sent to the upper pharynx along the tongue surface, and the base of the tongue is separated from the posterior wall of the oropharynx.

2. Reverse insertion method: insert the pharyngeal curved part of the oropharyngeal tube into the mouth to the palate, rotate it 180° when the inner orifice is close to the posterior wall of the oropharynx, and push it down to a suitable position when the patient inhales, fix it with tape after the ventilation is smooth.
