Ventilator settings and blood gas analysis results are: FIO2 0.70 Mandatory rate 14 VT 350 mL PEEP 5 cm H2O pH 7.35 PaCO2 35 mm Hg PaO2 40 mm Hg HCO3 - 19 mEq/L BE -6 mEq/L SO2 (calc) 74% A respiratory therapist should recommend A. changing to SIMV mode. increasing to 10 cm H2O PEEP. C. changing to 5 cm H2O CPAP. D. increasing to 400 mL VT. EXPLANATIONS (h) A. Changing to SIMV will not treat the hypoxemia. It may also cause a decrease in minute ventilation and adverse changes in the acid-base status. (c) B. The increase in PEEP will increase FRC, decrease the intrapulmonary shunt, and address the hypoxemia. (h) C. Changing to CPAP may decrease minute ventilation causing adverse changes in the acid-base status. (u) D. Increasing the tidal volume will further decrease the PaCO2. It will not significantly improve oxygenation. √ 2. When instructing a patient on the administration of umeclidinium/vilanterol (Anoro Ellipta), which of the following is most important to emphasize?
