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 edema
-airway inflammation disease
-CNS depression


List five possible signs or symptoms of respiratory failure

-inability to cough
-increased RR
-cardiac arrest


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

Unconscious patient


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

Frequent suctioning
Semi conscious patient


List four possible hazards of using Nasopharyngeal airway

Nasal trauma
Gastric inflation


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
Unconscious patient
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
-gastric rupture
-not securing a tight mask fit can lead to improper ventilation


How long you can use and esophageal obturator for?

1-2 hours


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
(10 steps)

-Assure patient ventilation with OPA
-check balloon
-assemble mask
-lube it
-lift chin and position head
-insert mask till you seal the face
-seal mask and ventilate
-look for chest rise
-inflate balloon
-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

Wrong size
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


What does z-79 indicate on the tube?

That it was made with material that has passed the tissue toxicity test
