The correct size OPA is chosen by measuring from the first incisors to the angle of the jaw. The airway is then inserted into the person's mouth upside down. Once contact is made with the back of the throat, the airway is rotated 180 degrees, allowing for easy insertion, and assuring that the tongue is secured.

How do you fit an 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.
What are the sizes of airway?
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.
What is the correct size of oropharyngeal?
The tip of an appropriately sized OPA should just reach the angle of the patient's mandible (Fig. 6). An OPA that is too short is worse than one that is too long. An OPA that is too short will actually push the tongue back farther in the airway and make the obstruction complete.
What happens if an OPA is too big?
Too large an oral airway will either obstruct the glottis or may cause coughing, gagging, or laryngospasm in a patient who is not deeply anesthetized. Too small an oral airway will push the tongue posteriorly and make the airway obstruction worse.
Can a nurse insert an oral airway?
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).
What size ET tube?
The average size of the tube for an adult male is 8.0, and an adult female is 7.0, though this is somewhat an institution dependent practice. Pediatric tubes are sized using the equation: size = ((age/4) +4) for uncuffed ETTs, with cuffed tubes being one-half size smaller.
What is the typical size of a nasopharyngeal airway in adults?
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 are the indications for an oral airway?
As described, the main indication for use of an OPA is if a patient is at risk of airway obstruction due to relaxed upper airway muscles or blockage of the airway by the tongue.
What can happen if the oropharyngeal airway is too large pals?
Inserting an OPA Too large of an airway device can damage the throat. Too small of an airway device can press the tongue into the airway.
When inserting an oropharyngeal airway the crossed finger technique is used to?
Use the thumbs as a lever to lift the mandible upward. Opening the Mouth Using the Crossed-Finger Method If you need to open a patient's mouth—to suction the oropharynx, to perform a fin- ger sweep, or to insert an oral airway—the method most commonly used is the crossed-finger technique (Figure 9-7■).

What is the correct method of sizing an oropharyngeal airway for an adult?
Determine the appropriate size of the 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.
What is the first step in the use of an oropharyngeal airway?
Technique 1: First, open the mouth. Then, using a tongue depressor, push down on the tongue and, with the tip pointed caudally, insert the oropharyngeal airway directly into the mouth over the tongue.
When do you insert an oral 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 does an oral airway work?
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.
Where should the airway be placed in the mouth?
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).
How to open the upper airway?
Avoid moving the neck and use only the jaw-thrust maneuver or chin lift without head tilt to manually facilitate opening of the upper airway.
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.
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.
How to determine airway size?
To estimate an appropriate airway size, the distance between the maxillary incisors and the angle of the mandible has been recommended by the European Resuscitation Council guidelines.5In contrast, the American Heart Association guidelines recommend the use of the distance between the corner of the mouth and the angle of the mandible.6Despite these guidelines, no study has evaluated the utility of these external facial measurements for the selection of an appropriate airway size. The present study, using airway sizes based upon the two guidelines, aimed to determine which of the two guidelines resulted in an airway providing optimal ventilation parameters. Both mask and mechanical ventilations as well as the endoscopic view of the airway tip via a fibreoptic bronchoscope were used in the assessment.
What are the two external facial measurements that are recommended for estimating the size of the oropharyngeal air?
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.
Why is the upper airway important?
The risk of upper airway collapse increases in unconscious or anaesthetised patients, because a low central drive decreases the activity of the pharyngeal dilator muscles. 1,2 An oropharyngeal airway is helpful in relieving such upper airway obstruction as it moves the tongue and hypopharyngeal structures forward, improving airway patency. 3 Although the airway is simple to use, it is important to select an appropriate size. If the airway is too small, its distal end will be obstructed by the tongue, resulting in inadequate ventilation 4 and, if too big, there is a risk of traumatic injury to the surrounding laryngeal structures.
Which airway is more advantageous?
With regard to adequate ventilation in conjunction with an acceptable endoscopic view, an oropharyngeal airway whose size is based upon the distance from the maxillary incisors to the angle of the mandible is more advantageous than if based upon the distance from the corner of the mouth to the angle of the mandible.
Which airway passes beyond the epiglottis?
In the maxillary incisors to the angle of the mandible group, the tip of the airway passed beyond the tip of the epiglottis in 22% of patients, in contrast, none of the airways in the corner of the mouth to the angle of the mandible group passed beyond the tip of the epiglottis.
How to insert an OP airway?
An OP airway can be inserted into an adult casualty’s mouth using the rotation method: Tilt the casualty’s head back; open the casualty’s mouth with one hand using jaw support (or jaw thrust, if necessary) Hold the OP airway by the flange with the tip pointing upwards towards the roof of the casualty’s mouth.
Where should an OP airway be inserted?
The OP airway should be inserted into the unresponsive breathing casualty’s mouth either when they are on their back (pre ferred position) or on their side.
What is an OP airway?
Oropharyngeal (OP) airways are curved plastic devices that assist in the maintenance of an adequate airway in the unresponsive casualty. The OP airway by itself does not replace correct airway management practices and should only be considered as a tool to assist in the management of a casualty’s airway.
How long are OP airways?
OP airways come in a range of sizes allowing for insertion into different-sized casualties. The smallest OP airways are approximately 5 cm long and the larger OP airways are over 10 cm long. The bite block also assists with size recognition as there are different colours for different sizes.
Can you rotate an OP airway?
If inserting an OP airway into a child or infant, DO NOT rotate the device, but gently slide it straight in
Can an OP airway be inserted into an adult's mouth?
An OP airway can be inserted into an adult casualty’s mouth using the rotation method:
How Can You Naturally Increase Airway Size?

Does Airway Size Cause Sinus or Nasal Cavity Issues?
John: Okay. Can you have issues with your airway size related to your sinuses and nasal cavity as well?
Which incisors are more acceptable for OPA?
These results indicate that to obtain adequate ventilation in conjunction with an acceptable endoscopic view, the maxillary incisors to the angle of the mandible measurement for an OPA is more acceptable.
What to do if resistance is felt during insertion of a nasopharyngeal air?
If resistance is felt during insertion of a nasopharyngeal airway, stop and try the other naris.
Why do we need nasopharyngeal airways?
Nasopharyngeal airways are also used to keep the airway open and can be used with patients who are conscious or semi-conscious. For example, semi-conscious patients may need an NPA because they are at risk for airway obstruction but cannot have an OPA placed due to an intact gag reflex. Polyvinyl chloride nasopharyngeal airway tubes (NPATs) are readily available and are commonly used by anesthesia providers for patients either during induction or in the immediate postoperative period to help prevent obstruction of the airway. 8 NPAs may also work well for patients who are clenching their jaw, which makes inserting an oral airway difficult, and for those who are semi-conscious and need frequent nasal-tracheal suctioning.
What happens if an OPA is too small?
Although airways are simple to use, it is important to select an appropriate size. If the airway is too small, its distal end will be obstructed by the tongue, resulting in inadequate ventilation. 3 Radiographic assessment of the position of OPAs also demonstrated that the distal end of the airway may lodge in the vallecula or can be obstructed by the epiglottis. 5 If the OPA is too large, there is a risk of traumatic injury to the surrounding laryngeal structures 3, and possibly laryngospasm. 5
How to avoid trauma to the tongue?
Avoid forcing an oropharyngeal airway, which can lead to trauma to the lips and tongue. Use caution when twisting the oropharyngeal 180 degrees to avoid trauma along the hard palate. Use a water-soluble lubricant when inserting a nasopharyngeal airway.
How to determine OPA?
There are two common facial measurements recommended for determining the proper sized OPA: the distances between the maxillary incisors to the angle of the mandible, and the distance from the corner of the mouth to the angle of the mandible.
How to use OPA?
As you are inserting the device and it approaches the posterior pharynx, rotate the device 180 degrees into the correct position. Another option is to use a tongue blade to gently depress the tongue caudally, and then place the OPA with the curved portion facing the tongue from the beginning.
