, Which of the following statements regarding oxygenation and ventilation is correct?
A. In carbon monoxide (CO) poisoning, ventilation is impaired because CO binds to oxygen very
quickly.

adequate oxygenation.
C. Oxygenation without adequate ventilation can occur in climbers who quickly ascend to an
altitude of lower atmospheric pressure.
D. Oxygenation is the movement of air into and out of the lungs, whereas ventilation is the
exchange of gases. - Answers -B. In mines or confined places, where oxygen levels are low,
ventilation may continue despite adequate oxygenation
Which of the following statements regarding positive-pressure ventilation is correct?
A. With positive-pressure ventilation, more volume is required to have the same effects as
normal breathing.
B. Unlike negative-pressure ventilation, positive-pressure ventilation does not affect the
esophageal opening pressure.
C. To prevent hypotension, the EMT should increase the rate and force of positive-pressure
ventilation.
D. Positive-pressure ventilation allows blood to naturally be pulled back to the heart from the
body. - Answers -A. With positive-pressure ventilation, more volume is required to have the
same effects as normal breathing
