ABG results are as follows:
pH 7.28
PaCO2 74 torr HCO3 20 mEq/L PaO2 315 torr
Which of the following would you recommend?
A. Apply BiPAP with: IPAP 20 cm H2O, EPAP 5 cm H2O, FiO2 30%
B. Intubate and apply: SIMV, tidal volume 600 mL, rate 6/min, FiO2 40%
C. Intubate and apply: A/C ventilation, tidal volume 450 mL, rate 12/min, FiO2 50%
D. Apply CPAP at 10 cm H2O and an FiO2 of 100% -
