A respiratory rate of 40 breaths/min is required to ventilate an infant with an MVP-10. The in-spiratory and expiratory time settings that would provide 40 breaths/min are which of the fol-lowing? Inspiratory Time Expiratory Time
 
  a. 0.25 s 0.9 s c. 0.75 s 2 s
  b. 0.5 s 1 s d. 0.95 s 1.75 s

Question 2

During transport, an infant who is using a Bio-Med MVP-10 unit in the intermittent mandatory ventilation mode with 60 fractional inspired oxygen requires 3 L/min of oxygen and 2 L/min of air
 
  to maintain the fractional inspired oxygen and desired peak pressure. An E cylinder with 2200 pounds per square inch gauge of oxygen would last _____ minutes.
  a. 88.8 c. 207.3
  b. 155.5 d. 314.3

Answer to Question 1

ANS: B
The total cycle time for 40 breaths/min is 60  40 = 1.5 s. Inspiratory time plus expiratory time must equal 1.5 s. The only combination that adds up to 1.5 s is inspiratory time = 0.5 s and expir-atory time = 1 s.

Answer to Question 2

ANS: A
Pressure of gas supply = tank pressure  conversion factor = 2200 pounds per square inch gauge  0.28 = 622 L. 622 L  (3 L/min for the oxygen + 4 L/min for the fluidic logic) = 622  7 = 88.8 minutes.

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.

Before a vaccine is licensed in the USA, the Food and Drug Administration (FDA) reviews it for safety and effectiveness. The CDC then reviews all studies again, as well as the American Academy of Pediatrics and the American Academy of Family Physicians. Every lot of vaccine is tested before administration to the public, and the FDA regularly inspects vaccine manufacturers' facilities.
