Data listed were obtained while an adult patient was receiving volume controlled ventilation with an FIO2 of 0.50. At 1300: Plateau pressure (cm H2O) – 30 PEEP – (cm H2O) – 0 PaO2 (torr) – 40 PvO2 (torr) – 28 B/P(mm Hg) – 140/90 At 1600: Plateau pressure – 35 PEEP – 6 PaO2 – 60 PvO2 – 39 B/P – 130/90 At 1700: Plateau pressure – 36 PEEP – 8 PaO2 – 65 PvO2 – 43 B/P – 130/95 At 1800: Plateau pressure – 40 PEEP – 10 PaO2 – 70 PvO2 – 45 B/P – 120/80 At 1900: Plateau pressure – 42 PEEP – 12 PaO2 – 75 PvO2 – 42 B/P – 100/80. Which of the levels of PEEP is best for this patient?
