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.
