A pulse oximeter probe applied to a person's finger. A pulse oximeter is a medical device that indirectly monitors the oxygen saturation of a patient's blood (as opposed to measuring oxygen saturation directly through a blood sample) and changes in blood volume in the skin, producing a photoplethysmogram that may be further processed into other measurements.

Example pulse oximeter Pulse oximetry is a method used to estimate the percentage of oxygen bound to hemoglobin in the blood. [ 10 ] This approximation to SaO 2 is designated SpO 2 (peripheral oxygen saturation).
Dissolved oxygen levels required by various species in the Chesapeake Bay (US). In aquatic environments, oxygen saturation is a ratio of the concentration of "dissolved oxygen" (DO, O 2), to the maximum amount of oxygen that will dissolve in that water body, at the temperature and pressure which constitute stable equilibrium conditions.
During the treatment target SpO2 values are in the range of 75% - 89%. ... to calculate HTi based on readings from a USB connected Pulse Oximeter. References
Finger tip carboxyhemoglobin saturation monitor.. A CO-oximeter is a device that measures the oxygen carrying state of hemoglobin in a blood specimen, including oxygen-carrying hemoglobin (O2Hb), non-oxygen-carrying but normal hemoglobin (HHb) (formerly, but incorrectly, referred to as 'reduced' hemoglobin), as well as the dyshemoglobins such as carboxyhemoglobin (COHb) and methemoglobin (MetHb).
He led the team of pulse oximeter engineers which later developed the Ohmeda Biox 3700 [3] which was widely used in the anesthesia market in the mid-1980s. The first commercially available oximeters were produced by Hewlett-Packard, and were large, cumbersome, and expensive. These devices were of limited value because they were largely focused ...
