PO

Short for Pulse Oximeter.

A PO is a device used to monitor the oxygen in a patient's blood. It shines light through a patient's finger, toe, nose, earlobe, or the patient's forhead, and another sensor on the other side of the light wave measures how the light is being absorbed.

1. He's on a PO machine, and they are going to have to put hom on the ventilator, because his oxygen is 85 so he is having another set of desat episodes.
