Quizplus · Accepted Answer

The correct size of an oropharyngeal airway can be estimated by measuring the distance from the corner of the mouth to the ear lobe. This is because the distance between these two points correlates with the distance from the front teeth to the angle of the jaw, which is the correct size of the oropharyngeal airway. Measuring the distance from the tip of the nose to the ear lobe or the width of the mouth is not accurate enough to determine the correct size. Measuring the distance from the angle of the jaw to the larynx is also not a reliable method as the angle of the jaw may vary depending on the position of the head.
