What is the inspiratory time-to-expiratory time ratio given the following data: frequency of 12 breaths/min; inspiratory time of 0.90 second?
A) 1:0.22
B) 1:2
C) 1:4.6
D) 1:6.4

Question

Inspiratory time-to-expiratory time ratio = Inspiratory time/Expiratory time and Expiratory time = Total cycle time - Inspiratory time.Inspiratory time-to-expiratory time ratio = Inspiratory time/Total cycle time - Inspiratory time.Total cycle time = 60 ÷ 12 = 5 s.Inspiratory time-to-expiratory time ratio = 0.9/5 - 0.9 = 0.9/4.1.Reduce the inspiratory time-to-expiratory time ratio to its simplest form; divide the numerator and the denominator by inspiratory time.0.9 ÷ 0.9/4.1 ÷ 0.9 = 1:4.56,or 1:4.6.
