A Patient Is Receiving Mechanical Ventilation with a Fractional Inspired

question 52

Multiple Choice

A patient is receiving mechanical ventilation with a fractional inspired oxygen (F_IO₂) of 0.85 and a positive-end-expiratory pressure (PEEP) of 5 cm H₂O.His arterial partial pressure of oxygen (P_aO₂) is 68 mm Hg,arterial oxygen saturation (S_aO₂) is 88%,and partial pressure of end-tidal carbon dioxide (PetCO₂) is 32 mm Hg.Over the next few minutes his PEEP is titrated resulting in the following data: $A patient is receiving mechanical ventilation with a fractional inspired oxygen (FIO2) of 0.85 and a positive-end-expiratory pressure (PEEP) of 5 cm H2O.His arterial partial pressure of oxygen (PaO2) is 68 mm Hg,arterial oxygen saturation (SaO2) is 88%,and partial pressure of end-tidal carbon dioxide (PetCO2) is 32 mm Hg.Over the next few minutes his PEEP is titrated resulting in the following data: At 0740 the single breath carbon dioxide curve (SBCO2) curve shifted to the right.What action should the respiratory therapist take at this time? A) Increase the FIO2 to 0.90. B) Reduce the set tidal volume. C) Continue to increase the PEEP. D) Reduce the PEEP to 12 cm H2O.$ At 0740 the single breath carbon dioxide curve (SBCO₂) curve shifted to the right.What action should the respiratory therapist take at this time?
