What fractional inspired oxygen (FIO2) setting should be set on the ventilator when the patient currently has a partial pressure of oxygen (PaO2) of 53 mm Hg while receiving 50% oxygen and the desired PaO2 is 90 mm Hg?

A 45-year-old, 73-inch-tall, 200 lb male patient is admitted to the emergency department with an exacerbation of myasthenia gravis. The respiratory therapist assesses the patient and finds the patient’s maximum inspiratory pressure is -15 cm H2O and his vital capacity is 1050 mL. It is decided that the patient requires ventilatory support. The most appropriate ventilator settings for this patient are which of the following?
