Functional upper airway obstruction in the unconscious patient involves soft tissue collapse between
++
++
++
A. the tongue and the posterior pharynx
++
++
B. the epiglottis and the posterior pharynx
++
++
C. the soft palate and the posterior pharynx
++
++
D. the tongue and the palate
++
++
+
++
(E) All of the above. All of these obstructions may be relieved by a combination of placing an OPA and performing a jaw thrust.
++
++
++
The most effective means of relieving a non-pathologic upper airway obstruction in the unconscious patient is
++
++
++
A. placing the patient in sniffing position
++
++
B. placing a nasopharyngeal airway
++
++
C. simple extension of the neck
++
++
D. performing a jaw thrust
++
++
E. placing an extraglottic device
+
++
(D) Performance of a jaw thrust has been shown to be the single most effective means of relieving a non-pathologic obstruction in the unconscious patient.
++
++
++
Difficult mask-ventilation is associated with
++
++
++
++
++
++
++
C. difficult laryngoscopy
++
++
D. the presence of dentures
++
++
+
++
(E) Increasing age is a multifactorial risk factor likely representing a combination of decreased tissue elasticity, neck and jaw mobility, and lack of teeth. Difficult laryngoscopy is an important predictor for DMV.
