An adult patient develops severe hypoxemia from a pneumonia and goes into cardiac arrest. He is successfully resuscitated with the machine shown above. The following day, it is noted that a sat probe on his right forefinger and a sat probe on his ear reads 75% whereas a sat probe on the toe reads 98%. He does have a right femoral arterial cannula and an ABG drawn there reads a PaO2 of 150mmHg. However, when you do a fresh ABG stick from the right radial artery, the PaO2 is 40mmHg.
Challenge: What machine is he on?
