Compute the inspiratory time necessary to ensure 100% of the volume is delivered to an intubat-ed patient with a Cs = 60 mL/cm H2O and the Raw = 6 cm H2O/(L/sec)

a. 0.36 second
b. 0.5 second
c. 1.4 second
d. 1.8 second

ANS: D
Time constant (TC) = C (L/cm H2O) ? R (cm H2O/(L/sec)). 100% of the volume will be delivered in 5 time constants. Therefore, multiply 5 times the time constant.
