A client is mechanically ventilated due to acute respiratory distress syndrome (ARDS). The ventilator is set to continuous mandatory ventilation (CMV) mode, RR 35, PEEP 5 cmH 2 o, FiO2 0.75. An arterial blood gas is drawn by the nurse. The results are pH 7.32, PCO2 60mmHg, HCO 3 16 mEq/L (16 mmol/L) and PO2 45 mmHg.

Based on these findings what changes to the ventilator need to be made?

Reference Ranges:
pH: 7.35-7.45
pCO 2 : 35-45 mmHg
pO 2 : 80-100 mmHg
HCO 3 : 22-26 mEq/L (22-26 mmol/L)
