What’s a pulse oximeter?
This tool that’s common place in hospitals and clinical settings is still a bit mystifying to most of us. So, what is it? Well, aside from the finger clippie thing (that’s a technical term) they put on you at the hospital – it’s an electronic device that measures the oxygen saturation levels in your blood cells. It performs this task quickly and without using needles or taking a blood sample, allowing for oxygen levels to be monitored in real-time.
Fun fact – pulse oximeters are usually attached to your fingers, but can also be attached to the forehead, foot, ears, toes, or even your nose. Let that be a reminder to be kind to your medical staff.
