You have just placed a chronic obstructive pulmonary disease (COPD) patient on intermittent mandatory ventilation at a rate of 8/min, a VT of 750 ml, and an FIO2 of 0.40. To ensure proper equilibration between the alveolar and arterial gas tensions, how long should you wait before drawing a sample for measurement of the ABG?

A) 5 minutes B) 10 minutes C) 15 minutes D) 30 minutes A) 5 minutes B) 10 minutes C) 15 minutes D) 30 minutes

When the patient stabilizes on mechanical ventilation with a PEEP of 12 cm H2O and the FIO2 has been reduced to 0.40, how should the PEEP level reduced?

A) in increments of 2 cm H2O every 6 hours B) in increments of 3 to 5 cm H2O every 2 hours C) in increments of 3 to 5 cm H2O every one hour D) in increments of 5 cm H2O every 2 hours A) in increments of 2 cm H2O every 6 hours B) in increments of 3 to 5 cm H2O every 2 hours C) in increments of 3 to 5 cm H2O every one hour D) in increments of 5 cm H2O every 2 hours
