You are a medical student rotating on ICU, and on your first day, you witness a test. An intubated patient is put onto 100% oxygen for 10 minutes. An ABG and electrolytes are checked and normal. His vital signs, including temperature, are normal. He is then taken off the ventilator and observed for ten minutes. A repeat ABG is sent.

Challenge: What test did you just witness?
