EMT Airway Exam Study Guide Exam
Questions with Complete Solutions
How do we measure for placement of OPA? - Answer-The OPA is sized by measuring
from the center of the mouth to the angle of the jaw, or from the corner of the mouth to
the earlobe. The mouth is opened using the "crossed or scissors" finger technique.
OPA - Answer-oropharyngeal airway (oral airway)
Preferred suction catheter for suctioning of the oropharynx - Answer-Tips with curved
contour allow for a easy, rapid placement in the oropharnyx
Oropharynx - Answer-posterior to oral cavity
aspiration - Answer-the introduction of vomitus or other foreign material into the lungs
What is the proper sequence for suctioning of a patients airway? - Answer-1. Turn of the
assembled unit and make sure it is at 300mm Hg. 2.Measure the catheter 3. Turn the

catheter to the premeasured depth and apply suction in a circular motion as you
withdraw the cathetar. No more than 15 seconds in an adult.
Diffusion - Answer-Site of oxygen and carbon dioxide exchange
Inhalation - Answer-Active process in which the diaphragm and intercostal muscles
contract
intercostal muscles - Answer-muscles between the ribs
Exhalation - Answer-Passive process in which the diaphragm and intercostal muscles
relax
phrenic nerve - Answer-innervates the diaphragm, allowing it to contract
Child breathing rate - Answer-15-30 breaths/min
Infant breathing rate - Answer-25-40 breaths/min
tidal volume - Answer-Adequate depth
What is the most common obstruction? - Answer-Tongue
What hash technique do you use for snoring respiration? - Answer-Jaw technique
