Short Inspiratory Times Effects
Pretest
Which of the following is a result of very short inspiratory times?
A.Gas trapping
B.Inadequate tidal volume delivery
C.Decreased PaCO2
D.Increased mean airway pressure
E.None of the above
Post Test
Which of the following is a result of very short inspiratory times?
A.Gas trapping
B.Inadequate tidal volume delivery
C.Decreased PaCO2
D.Increased mean airway pressure
E.None of the above
Answer: B
Very short inspiratory times do not allow for adequate tidal volume delivery. With shortened inspiratory times, the mean airway pressure is lower; gas trapping does not occur in this setting as it does with prolonged inspiratory times; and, with inadequate tidal volume breathing, carbon dioxide actually may rise.
