Increased transairway pressure is associated with which two of the following changes?
1)Increased airway resistance
2)Decreased airway resistance
3)Increased static compliance
4)Decreased static compliance
A) 3 and 4
B) 1 and 3
C) 2 and 4
D) 1 and 2

Question

Quizplus · Accepted Answer

Transairway pressure is the pressure required to overcome airflow resistance and is calculated by subtracting the plateau pressure from the peak inspiratory pressure.An increase in the peak inspiratory pressure with a constant plateau pressure increases the transairway pressure.Another way to increase transairway pressure would be to decrease the plateau pressure (i.e.,improved static compliance)and keep a constant peak inspiratory pressure.
