Santamedical Generation 2 Fingertip Pulse Oximeter Oximetry Blood Oxygen Saturation Monitor with Batteries and Lanyard

Saturation (the level of oxygen in the blood) is measured using a pulse oximeter.

Oxygen saturation: normal and pathological values

In this final part, we look at how to measure oxygen saturation before giving oxygen. Taking a baseline reading is essential, as levels can rise quickly once oxygen is administered. A small, simple tool — but a critical step in emergency care. Missed Part 1 or 2? Find them on our profile. Follow us for more training content. | Scuba Scape
