Flashcards in Airway Final Deck (92)
Under what circumstances will some form of airway control always be required?
Situation where the patient cannot adequately Ventilate themselves.
-airway obstruction from tongue
List for possible causes of respiratory failure
-tongue blocking airway
-airway inflammation disease
List five possible signs or symptoms of respiratory failure
-inability to cough
What is the most common cause of airway obstruction?
Tongue blocking the airway
Name an indication for the use of oral pharyngeal airway or OPA
List for possible complications for using an OPA
5 are listed
-Does not protect from vomit
-Too long an OPA can occlude the trachea by hitting the larynx
-too short an airway can push the tongue back
-soft palate injury
How does the oropharyngeal airway help maintain the airway?
-By lifting the tongue and putting it out of the way
-air is also fed through the berman channels or Gudel hole
What are the two types of oropharyngeal airways?
As well as their differences
Guedel - center hole
Berman - side channels
How do you measure if oropharyngeal airway has proper fit?
Measure from mouth to jawline
What are the five steps to insert an oropharyngeal airway?
-use head neck chin lift to move tongue forward
-insert OPA in reverse
-feed into mouth till resistance is met
-then rotate it 180 degrees and advance till its sitting above the teeth
List 2 indications for the use of nasopharyngeal airways
Semi conscious patient
List four possible hazards of using Nasopharyngeal airway
How do you measure proper size for nasopharyngeal airway?
Measure from the nose to the tragus
What is the major function of an esophageal obturator airway?
Tube with cuff plugs that esophagus and prevent aspiration into the airways.
But still has a ventilation holes on the tube
What are three indications for the application of an esophageal obturator airway
Possibility of aspiration
Short-term ventilation while making plans for intubation
What are five contraindications for the use of an esophageal obturator airway?
-Patients were less than 5 feet tall
-Conscious or semi conscious patients
-Upper airway trauma
-Known esophageal damage
What are three possible complications that may result from inappropriate use of the esophageal obturator airway?
-intubation of the trachea
-not securing a tight mask fit can lead to improper ventilation
How long you can use and esophageal obturator for?
Describe the difference between the esophageal obturator and the esophageal gastric tube airway
-The esophageal gastric tube airway has a port for you to suction gastric contents
What are the steps to correctly insert and esophageal obturator airway
-Assure patient ventilation with OPA
-lift chin and position head
-insert mask till you seal the face
-seal mask and ventilate
-look for chest rise
-auscultation and evaluate respirations
Where should a properly inserted tip of an esophageal obturator be positioned?
In the esophagus
What is the advantage of a Combitube over and esophageal obturator?
Insertion of the tube in either the trachea or the esophagus will allow you to ventilate the patient
What is the greatest complication in using a Combitube?
Not identifying where you inserted the tube and what adapter you should be ventilating with.
What special skills and abilities are required to perform airway control?
Knowledge of respiratory anatomy
When inserting a Combitube how would you know that you inserted a tube into the esophagus or the trachea?
Ventilating from the blue or the first port causes a chest rise and breath sounds indicates you inserted the tube into the esophagus.
- if not ventilate on the second port and recheck for breath sounds because it looks like you into intubated the trachea
When properly position where is a laryngeal mask airway located?
In the hypopharynx right over the trachea
List three possible complications associated with the placement and use of the laryngeal mask
It can fold on to itself and occlude airway
What is the maximum amount of airway pressure that you can use with and laryngeal mask airway?
What are the benefits of using an LMA over other forms of airway control
Less irritating to the airway
Easier to install compared to endotracheal tube
