WEBPulse oximeters measure how much of the hemoglobin in blood is carrying oxygen (oxygen saturation). If you work in healthcare (or have been patient !) you are very likely to have come across pulse oximeters. You can find them in areas such as operating rooms, recovery, critical care, wards, and ambulances.
