Background: Two external facial measurements have been recommended as reference criteria for estimating appropriate oropharyngeal airway sizes: the distances between the maxillary incisors to the angle of the mandible, and that from the corner of the mouth to the angle of the mandible.
How do you measure oropharyngeal airway size?
Choose the correct size by measuring the oropharyngeal airway against a patient’s face. When the tip is placed at the angle of the jaw the flange should align with the centre of the top teeth (i.e. measure ‘hard to hard’).
What is an oropharyngeal airway insertion guide?
This oropharyngeal airway insertion guide provides a step-by-step approach to inserting an oropharyngeal airway (also called a Guedel airway) in an OSCE setting. Insertion of an oropharyngeal airway may be assessed in an OSCE as an individual skill, in combination with other airway management skills or as part of an ABCDE assessment.
How do you position an oropharyngeal airway in a stretcher?
Positioning for Oropharyngeal Airway The sniffing position—only in the absence of cervical spine injury: Position the patient supine on the stretcher. Align the upper airway for optimal air passage by placing the patient into a proper sniffing position.
How do you use an airway tip correctly?
Size: Use one that matches the distance between the corner of the patient’s mouth and angle of their jaw Insert into the mouth upside down (reduces risk of pushing tongue back) Once tip is around hard-soft palate junction, rotate 180˚ and advance the rest of the way If the patient gags it is unlikely they will tolerate this airway.
How do you measure and insert an oropharyngeal oral airway?
Open mouth using crossed- finger technique or tongue-jaw lift. Insert airway halfway, with curved end facing roof of mouth; then rotate airway 180° into position. Determine unresponsiveness, then measure distance of insertion (earlobe to corner of mouth). Select correct size of airway.
How do you measure and insert OPA?

It around and then locate it into the airway nicely into the oropharynx.
When measuring for an oropharyngeal airway it should extend?
An appropriately sized oropharyngeal airway device should extend from the corner of the mouth to the angle of the mandible (Fig. 16-9,B). When placed appropriately, its distal end snugly curves around the base of the tongue, without the proximal end protruding out of the mouth.

What are the 2 types of oropharyngeal airways?
There are two types of airway adjuncts. One is an oropharyngeal airway, and the other is a nasopharyngeal airway.
What are the sizes of OPA?
Adult sizes are the #8 (8 cm), #9 (9 cm), #10 (10 cm), and #11 (11 cm), designated according to the height measured horizontally from the flanges to the distal end of the airway. There may be variations in both shape and length between different OPA manufacturers.
What is the technique to select the best sized oropharyngeal airway quizlet?
What is the best technique to select the best sized oropharyngeal airway? Place the flange even with the mouth, measure along the jaw, correct airway will measure from the corner of the mouth to the end of the jaw.
What is the correct positioning for an oropharyngeal airway?
Hold the airway beside the patient's cheek with the flange at the corner of the mouth. The tip of an appropriately sized airway should just reach the angle of the mandibular ramus. Next, begin inserting the airway into the mouth with the tip pointed to the roof of the mouth (ie, concave up).
Do you tape oropharyngeal airway?
On arousal, the casualty will gag on the airway and may vomit, if it is not removed. Never tape the oral airway in place, as it should be quickly removed if the casualty wakes up. Never insert an oral airway on a conscious patient for training purposes, as it can provoke gagging, vomiting and possible aspiration.
How many NPA sizes are there?
When placing an NPA, the healthcare provider should be knowledgeable regarding the sizing of the NPA. Adult sizes range from 6 to 9 cm. Sizes 6 to 7 cm should be considered in the small adult, 7 to 8 cm in the medium size adult, and 8 to 9 cm in the large adult.
What can happen if the oropharyngeal airway is too large?
If the oropharyngeal airway is too large, it may obstruct the larynx, make a tight mask fit difficult, and traumatize laryngeal structures. If the oropharyngeal airway is too small or is inserted improperly, it pushes the tongue posteriorly, obstructing the airway.
How wide should an airway be?
Most airways are eight nautical miles (14 kilometers) wide, and the airway flight levels keep aircraft separated by at least 500 vertical feet from aircraft on the flight level above and below when operating under VFR.
Do you insert OPA for seizure?
1 Do not attempt to insert an OPA (oropharyngeal airway) during a seizure. Note: Most postictal patients do not need an OPA. If an OPA is used, be prepared to remove it as consciousness returns. Consider a nasopharyngeal (trumpet) airway.
When inserting an OPA the crossed finger technique is used to?
To insert an oropharyngeal airway using the cross-finger technique to open the patients mouth. One method of insertion is to turn the airway 180 degrees from its resting position as it is passed over the tongue to avoid pushing the tongue back into the pharynx.
Why do we insert OPA?
Use an oropharyngeal airway only if the patient is unconscious or minimally responsive because it may stimulate gagging, which poses a risk of aspiration. Nasopharyngeal airways are preferred for obtunded patients with intact gag reflexes.
Can an RN insert an OPA?
2.1 The Registered Nurse (RN), Registered Psychiatric Nurse (RPN), Licensed Practical Nurse (LPN), Graduate Nurse (GN), Graduate Psychiatric Nurse (GPN), Graduate Licensed Practical Nurse (GLPN) will insert, maintain, suction and remove an oropharyngeal airway (OPA).
Why do you need an oropharyngeal airway?
Use an oropharyngeal airway only if the patient is unconscious or minimally responsive because it may stimulate gagging, which poses a risk of aspiration. Nasopharyngeal airways are preferred for obtunded patients with intact gag reflexes.
How to sniff a patient?
To achieve the sniffing position, folded towels or other materials may need to be placed under the head, ne ck, or shoulders, so that the neck is flexed on the body and the head is extended on the neck. In obese patients, many folded towels or a commercial ramp device may be needed to sufficiently elevate the shoulders and neck. In children, padding is usually needed behind the shoulders to accommodate the enlarged occiput.
What is the goal of tongue relaxation?
The goal of all of these methods is to relieve upper airway obstruction caused by a relaxed tongue lying on the posterior pharyngeal wall.
Which airway is used concurrently with a nasopharyngeal airway?
An oropharyngeal airway used concurrently with a nasopharyngeal airway may improve oxygenation and ventilation.
What is the name of the apparatus used to remove easily accessible foreign bodies?
Various sizes of oropharyngeal airways. Suctioning apparatus and Yankauer catheter; Magill forceps (if needed to remove easily accessible foreign bodies), to clear the pharynx as needed. Nasogastric tube, to relieve gastric insufflation as needed.
Which notch is best for opening the upper airway?
Aligning the external auditory canal with the sternal notch may help open the upper airway and establishes the best position to view the airway if endotracheal intubation becomes necessary.
