EMT Module 3 Exam Questions and
Answers: Airway
What is the preferred initial method of ventilations for one person? - Answer-mouth to mask ventilation
with supplemental oxygen
What is the preferred initial method of ventilations for two people? - Answer-BVM with supplemental
oxygen
For the BVM, is one rescuer or two rescuer preferred and why? - Answer-Two rescuers because one
EMT can maintain a mask seal by securing the mask to the patient's face, while the other EMT squeezes
the bag
How do you know if ventilations are adequate? - Answer-If the patients chest rises and falls within each
ventilation
How does the nasal cannula work? - Answer-delivers oxygen through two small, tubelike prongs that fit
into the patient's nostril
How much oxygen does the nasal cannula deliver? - Answer-24 to 44% inspired oxygen when the
flowmeter is set at 1 to 6 L/min
For the nasal cannula, what flow rate should you not pass? - Answer-6 L/min
,When do you use the nasal cannula? - Answer-for a patient that does not accept a nonrebreathing mask
medical patients without respiratory compromise
stable cardiac patients without signs of MI
When do you use the partial rebreather? - Answer-for patients who show that they are suffering from
hyperventilation syndrome
how do you use the partial rebreather? - Answer-similar to a nonrebreathing mask, except there is no
one-way valve between the mask and reservoir
for the partial rebreather, what is a downside? - Answer-patients rebreathe a small amount of their
exhaled air.
this can also be a benefit if you want to increase the patient's partial pressure of carbon dioxide
how much oxygen is delivered by the partial rebreather? - Answer-about 80 to 90% of oxygen
when do you use the nonrebreather? - Answer-for patients who are breathing adequately but are
suspected of showing signs of hypoxia
how do you use the nonrebreather? - Answer-mask is a combination of a mask and a reservoir system
oxygen fills the reservoir bag and is attached by a one-way valve
, you must be sure that the reservoir bag is full before placing the mask on the patient. make sure the bag
stays inflated.
use a pediatric nonrebreathing mask for infants and children
why is it called a nonrebreather mask? - Answer-because the exhaled gas escapes through a flapper
valve port at the cheek areas of the mask. this prevents the patient from rebreathing exhaled gases
how much oxygen does a nonrebreathing mask deliver? - Answer-up to 95% oxygen at a flow rate of 15
L/min
how do you use a mouth to mask? - Answer-open airway with head tilt chin lift, insert an oral or nasal
airway if possible, connect the one-way valve to the face mask and place the mask on the patient's face.
blow through the one-way valve
blow slowly until you see adequate chest rise
when do you use the mouth to mask? - Answer-this is the best initial method of ventilations for one
rescuer
for the mouth to mask, how do you know if you are giving successful ventilations? - Answer-when you
see the patient's color improving, chest rise and fall, and do not meet resistance when ventilating
you should also feel air escape when the patient exhales
can you administer high-flow oxygen through the inlet valve of the mouth to mask? - Answer-yes
what is the BVM? - Answer-a bag valve mask
