Answer to Question 1

ANS: B
Commonly used output control valves include the pneumatic diaphragm, electromagnetic pop-pet/plunger valve, and the proportional valve. Descriptions of these devices can be found in res-piratory care equipment textbooks.

Answer to Question 2

ANS: D
To understand mechanical ventilators, we must first understand their four basic functions:
 Input power
 Power transmission and conversion
 Control system
 Output (pressure, volume, and flow waveforms)

Did you know?

As many as 28% of hospitalized patients requiring mechanical ventilators to help them breathe (for more than 48 hours) will develop ventilator-associated pneumonia. Current therapy involves intravenous antibiotics, but new antibiotics that can be inhaled (and more directly treat the infection) are being developed.

Did you know?

As the western states of America were settled, pioneers often had to drink rancid water from ponds and other sources. This often resulted in chronic diarrhea, causing many cases of dehydration and death that could have been avoided if clean water had been available.

Did you know?

Although the Roman numeral for the number 4 has always been taught to have been "IV," according to historians, the ancient Romans probably used "IIII" most of the time. This is partially backed up by the fact that early grandfather clocks displayed IIII for the number 4 instead of IV. Early clockmakers apparently thought that the IIII balanced out the VIII (used for the number 8) on the clock face and that it just looked better.
