Pharyngeal Airways | Types: Oropharyngeal and Nasopharyngeal |
Pharyngeal Airways Indications | Used To Protect the Airway |
Oropharyngeal | * Unconscious Patient * Support Base Of Tongue * Bite Block (With ET tube or seizure) * Facilitate oral suctioning |
Nasopharyngeal | * Conscious patient * Support base of tongue * Facilitate deep tracheal suctioning * Use to decrease trauma during nasotracheal suctioning |
Complications of Pharyngeal Airways | * This airway should be left unsecured * Gagging- remove airway suction give oxygen * Vomiting * Laryngospasm * Airway obstruction- remove, replace may be too small |
Complications of Nasopharyngeal Airways | * Trauma to mucosal (most common) - use a water-soluble water based lubricant. * Epistaxis (nasal bleeding) - change every 24 hrs * Increased airway resistance- use largest size |
Equipment Oropharyngeal Airways Size Determination | length should be equal to distance from angle of jaw to the tip of chin to past corner of the mouth. |
Equipment Nasopharyngeal Airways Size Determination | Outside diameter of airway should be equal to inside diameter of patient external nares. Length of airway is from tip of earlobe to center of nostrils. |
Airway Insertion Technique Oral | insert opposite its anatomic shape(upside down) to the back of the throat and then rotate into its correct position |
Airway Insertion Technique Nasal | inserted the way its anatomically shaped with water soluble lubricant |
