An increase in airway resistance during pressure ventilation will result in which of the following?
a. Plateau pressure (PPlateau) will increase.
b. Volume curve will resemble an igloo.
c. Inspiration will end prior to flow tapering to zero.
d. Pressure curve will become concave on inspiration.
ANS: C
With increased airway resistance the flow-time scalar will show a curve that is flatter in appear-ance. Flow will not drop to zero by the time the set inspiratory time is reached. Consequently, the ventilator and lung pressures do not equilibrate and this can affect the overall volume delivered to the patient.
