A reduction in compliance during pressure ventilation will cause which of the following?
a. Delivered tidal volume will decrease.
b. Volume curve will end under the zero line.
c. Inspiration will end prior to flow tapering to zero.
d. Pressure curve will become concave on inspiration.
ANS: A
When compliance is reduced during pressure ventilation the volume delivered will be reduced proportionally. The volume curve ending under the zero line is indicative of active exhalation. Inspiration ending prior to the flow tapering to zero is consistent with an increase in airway re-sistance. The pressure curve becoming concave on inspiration is consistent with inadequate flow.
