Which mode of ventilation is shown in the pressure-time scalar in the figure?
a. Pressure-controlled continuous mandatory ventilation (PC-CMV)
b. Volume-controlled continuous mandatory ventilation (VC-CMV)
c. Pressure-controlled intermittent mandato-ry ventilation (PC-IMV)
d. Volume-controlled intermittent mandatory ventilation (VC-IMV)
ANS: B
The pressure-time scalar shows all mandatory breaths, two time triggered and one pressure trig-gered. This means there is a combination of mandatory and assisted breaths. The scalar shows a peak inspiratory pressure that is not held. This means that the mode being shown is vol-ume-controlled continuous mandatory ventilation (VC-CMV).

A 59-kg IBW female patient is being mechanically ventilated in the CMV mode, f = 12/min, VT = 400 mL, PEEP = 5 cm H2O, FIO2 = 0.5. The ABG results on these settings show a respiratory acidosis and severe hypoxemia
The respiratory therapist increases the set VT and increases the PEEP to 12 cm H2O. The resulting ABGs show improved oxygenation, but the patient still has a respiratory acidosis. The respiratory acidosis may be due to which of the following? a. Tissue hypoxia b. Increased dead space c. Increased cardiac output d. Continued hypoventilation
