Note: Use appropirate size for the OPA. OPAs that are too big will obstruct the larynx or may cause trauma. OPAs that are too small may push the tongue back and obstruct the airway.
Nasopharyngeal airway (NPA): used as an alternative to OPAs and can be used in conscious or semiconscious patients. NPAs are usually inserted when inserting OPAs is difficult or dangerous.
- Find the appropriate size NPA by checking the distance from the tip of the patient’s nose to the earlobe
- Lubricate the airway
- Put the airway through the nostril in a backwards direction toward the floor of the nasopharynx
Note: Use appropirate size for the NPA. Wrong size NPAs can go to the esophagus and cause gastric inflation. Be careful when inserting the airway as it can irritate the mucosa or lacerate the tissue.
Suctioning helps maintain a patient’s airway by removing secretions, blood or vomit.
- Soft flexible catheters are used for the oropharynx and nasopharynx
- Rigid catheters are used only for oropharynx
- For oropharyngeal suctioning: measure the catheter by using the tip of the nose to the earlobe. Insert the catheter into the oropharynx right beyond the tongue.
- For endotracheal tube suctioning: put the catheter into the ET tube making sure not to be beyond the ET tube. Suction should be no more than 10 seconds.
