The flow sheet below, for a patient on pressure-controlled continuous mandatory ventilation (PC-CMV), demonstrates which of the following?
Time PIP (cm H2O) PEEP (cm H2O) Exhaled VT (mL)
0800 28 8 575
1000 28 8 558
1200 28 8 500
a. Lung compliance is increasing.
b. Dynamic compliance is decreasing.
c. Airway resistance is decreasing.
d. There is a leak in the ventilator circuit.
ANS: B
During pressure-controlled continuous mandatory ventilation (PC-CMV), a decrease in volume delivered is characteristic in a decreased dynamic compliance. If lung compliance increased or airway resistance decreased, the exhaled tidal volume would have increased. A leak in the venti-lator circuit would also drop the peak inspiratory pressure (PIP).
