A 68-year-old, 5-foot, 10-inch male patient with acute-on-chronic respiratory failure due to COPD has been placed on NIV with these settings: IPAP = 8 cm H2O, EPAP = 4 cm H2O, FIO2 = 0.28. The patient’s measured exhaled volume is 350 mL with a spontaneous respiratory rate of 24 breaths/min. The resulting arterial blood gas values are: pH = 7.27, PaCO2 = 77 mm Hg, PaO2 = 64 mm Hg, SaO2 = 88%, HCO3- = 36 mEq/L. What action should the respiratory therapist take at this time?
